Radeon vii overclockers: Radeon VII Overclocking for Dummies? : Amd

Radeon VII Undervolt/Overclock & Improved cooling guide. : Amd

Coming from a Vega 64 blower card to a Radeon VII I thought the tweaking process would be similar, but it isn’t as simple as the original vega cards were. With a Vega 64, the card came power and thermally limited with almost no overclocking headroom which made undervolting the best option for 99% of people who just wanted to game without serious software modifications and cooling solutions. With the Radeon VII there are a few perfectly viable options and ways you can go to improve the card depending on what you want and how comfortable you are with modifications. I’ve detailed these options below.

Tips and Warnings:

  • Be sure to save profiles with proper file names while tweaking your card. This will help you continue where you left off after a crash. Anything not saved as a profile will be dumped in the event of a crash and you will have to start from scratch.

  • Be careful and take your time when modifying your cooler if you go that route. It is not anyone’s fault but yours if you break your card modifying it.

  • Lets face it, you bought a $700 enthusiast grade video card and want to mess around with it. You can afford $30 for the paid version of 3d mark to make this process easier. Heaven does not push the card hard enough.

  • These cards are binned from the factory and the stock voltage of the card can give you a sign about how good your silicon is. My stock voltage was 1130mv, I’ve seen cards with only 1019mv as a stock voltage which is lower than my max undervolt. This thread is a great resource to see what you could expect for the potential of your card, average overclocks/undervolts, temperatures with various mods, fan speeds, etc.

Automatic undervolt with no other tweaking — Easiest and most simple way to reduce temps without losing any performance.

Manual undervolt/memory overclock — More complicated but you have more control over your card compared to the automatic undervolt.

  • This option yields about the same result as the automatic undervolt but with more freedoms such as: Changing the fan curve, overclocking memory, and lowering clock speeds below stock to reduce temperature and voltages. Using 3d mark you are going to want to setup a custom run looping one graphics test in windowed mode. Once you have that going you are going to want to get into Wattman and while running the graphics test and slowly lower the voltage on the frequency/voltage graph. If you notice any artifacts like flashing lights that aren’t supposed to be there or flashes of black screens, you’ve gone too far — add voltage or decrease clock speeds. Memory overclocking is not as important as it is with almost any other card but it is still worthwhile imo. Just slowly add frequency until you have problems then back it off 50mhz or so and leave it there.

Manual undervolt/memory overclock with cooler mods — Drastically reduce your temperatures and/or fan speeds compared to the other options.

  • If tjunction temperatures or fan speed/noise are still undesirable after an undervolt. Modifications to the cooler may be necessary. The most effective cooler mod would be the Mod done By u/CarbonFireOC — Radeon VII, how to drop 40C on your stock cooler temps. There is another mod called the washer mod but I do not personally recommend it for long term use as the extra mounting pressure on the package is concerning for the longevity of the card IMO. After lapping the cooler as per the above post, the washer mod made no difference in temps for me anyways. After you have the cooler mod done, expect lower temperatures and/or lower fan speeds compared to the manual undervolt without the cooler mod.

Manual core/memory overclock with cooler mods — With cooler mods and an overclock expect roughly stock fan speeds/temps but with much more performance.

  • Using the same cooler mod as shown above, you now have thermal headroom so you can push the card further than stock with acceptable noise levels and temperatures. This is a lot more exciting than overclocking Vega 10 because a daily overclock is actually viable on this card with reasonable power draw. Same drill with running 3d mark as the undervolt but instead you are going to set the power limit to +20% and slowly start increasing the frequency and voltages while 3d mark is running. Again, you are going to want to look out for any artifacts like flashing lights as when these show up the card is about to crash and is unstable. Be sure that your temps and fan speeds are manageable to you and stop adding voltage when you feel like it’s not worth the temps and noise. Personally I found this point to be around 1150mv for me. After you have found a stable core overclock bring your memory up, Just slowly add frequency until you have problems then back it off 50mhz or so and leave it there.

Final Notes:

After you’ve found settings you are happy with the settings you found and are stable in 3d mark be sure to test the card out in a few games and other applications until you are sure it is 100% stable. 3D Mark will get you close, but games can push cards differently than just a stress test and cause instability.

Test Methodology

Testing methodology has completely changed from our last GPU reviews, which were probably for the GTX 1070 Ti series cards. Most notably, we have overhauled the host test bench and had updated with new games. Our games selection is a careful one: Time is finite, and having analyzed our previous testing methodologies, we identified shortcomings where we were ultimately wasting time by testing too many games that didn’t provide meaningfully different data from our other tested titles. In order to better optimize our time available and test “smarter” (rather than “more,” which was one of our previous goals), we have selected games based upon the following criteria:

  • Game Engine: Most games run on the same group of popular engines. By choosing one game from each major engine (e.g. Unreal Engine), we can ensure that we are representing a wide sweep of games that just use the built-in engine-level optimizations
  • API: We have chosen a select group of DirectX 11 and DirectX 12 API integrations, as these are the most prevalent at this time. We will include more Vulkan API testing as more games ship with Vulkan
  • Popularity: Is it something people actually play?
  • Longevity: Regardless of popularity, how long can we reasonably expect that a game will go without updates? Updating games can hurt comparative data from past tests, which impacts our ability to cross-compare new data and old, as old data may no longer be comparable post-patch

Game graphics settings are defined in their respective charts.

We are also testing most games at all three popular resolutions – at least, we are for the high-end. This includes 4K, 1440p, and 1080p, which allows us to determine GPU scalability across multiple monitor types. More importantly, this allows us to start pinpointing the reason for performance uplift, rather than just saying there is performance uplift. If we know that performance boosts harder at 4K than 1080p, we might be able to call this indicative of a ROPs advantage, for instance. Understanding why performance behaves the way it does is critical for future expansion of our own knowledge, and thus prepares our content for smarter analysis in the future.

For the test bench proper, we are now using the following components:

Power Consumption

We’ll get to gaming benchmarks posthaste, but power consumption is too fun to put off any longer. Let’s start with plotting total system power consumption of the Radeon VII stock card, unmodified in any way. For our Ashes of the Singularity 4K benchmark, total system power consumption of the stock card is at about 420-430W peak, with the average closer to 390W to 400W. Remember, that’s total system power consumption, but we control the system carefully to ensure only the GPU causes power fluctuations.

Next is to plot the water cooling mod, but still with stock settings. This line would potentially reveal any power drop from reducing power leakage, something we’ve seen in previous liquid cooling mods. In this instance, unfortunately, there’s no meaningful change in power consumption. We don’t get the drop we sometimes get from power leakage reduction. Our next line plot is the overclocked water cooled card, which doesn’t use any powerplay table mods and only overclocks using the normal WattMan procedure. Our settings were technically 2030MHz core and 1200MHz memory, but the actual operating frequency is much lower than this due to misreporting by WattMan. Realistically, we’re more in the highly variable range of 1950MHz to 2000MHz. The result of this configuration is a total system power consumption peaking at 520W and averaging at about 455 to 460W.

The last line is the most impressive: For this one, we’re running a 100% power target and pushing card draw toward the 500W marker. Total system power consumption maxes-out at about 620W, an increase of around 200W over the stock Radeon VII test we first plotted. Performance doesn’t scale linearly with this, naturally, but that doesn’t matter for what we’re doing today. We’re just trying to see how far we can reasonably get Radeon VII, and it starts with this 620W peak total system consumption.

TimeSpy Extreme

We’ll start with TimeSpy Extreme, just because it’s a synthetic workload that heavily loads the GPU and memory independently, so we can get a fuller understanding of the maximum theoretical performance difference. These differences don’t necessarily scale to actual gameplay, but they are typically good indicators just of whether the overclock is even working; remember, with Vega, the biggest challenge is that WattMan might look like it’s accepting frequency overclocks, but the actual stability is worse and performance can decay as a result.

With TimeSpy Extreme, we placed a baseline score of 4278 points under complete auto, full stock cooler conditions. Our overclocking tests with the first driver revision also failed, often causing performance regressions even with small overclocks – you can see that in some of our results that place in the 1800 to 1900 territory; not that these have been resolved with the newest driver, which is why we’re revisiting today.

For the first overclock attempt with the new drivers, we scored 4562 points by operating with a 200MHz offset on our liquid cooled mod, using just a 120% power target and 1.125 GPU voltage. With the clocks set to a 220MHz offset and 1.162V, still using a 1000MHz stock memory frequency and 120% power target, we scored 4617 points. This is an increase over stock of about 8%, which gives you an idea for the upper limits of our liquid cooled Radeon VII before using powerplay table registry mods.

The final result was 4897 points, sparing everyone the slow increases in between, where we set the frequency to a 250MHz offset, voltage to 1. 237V – which is over the stock spec and uses powerplay mods – and power target to 100% offset, or 200% total power. The memory was 1200MHz. This result is 15% over the stock performance.

Moving to another TimeSpy chart, we can look at the individualized GT1 and GT2 scores, which helps us better visualize the specific areas of performance uplift. GT2 traditionally gets the biggest gains from memory overclocking, whereas GT1 gains from core overclocks as it better supports the specific workload.

The final overclock allowed for GT scores of 25.85 for GT2 and 35.38 for GT1, measured in FPS, and showing individual gains of 13.5% over the stock 31.18FPS for GT1 and 15.2% for GT2. Although the delta isn’t massive, it is common that we see AMD’s GT2 performance drag more of the weight as memory frequencies increase. AMD needs that memory bandwidth on its higher end GPUs.

Apex Legends

Before plotting thermals and talking about our overclock stepping and challenges in overclocking, it’d be good to get some gaming results presented for those most curious about performance gains and linearity of the overclock.

First up is Apex Legends, which has already demonstrated an uncommon performance advantage for Radeon VII versus the RTX 2080 competitor. We’re starting here because it’s sort of a best-case scenario for Radeon VII, so keep in mind that these won’t extrapolate to all other games.

At 4K and with all settings configured to high, using our river village benchmark with relatively high GPU load, the stock Radeon VII card placed at 56FPS AVG with lows at 43FPS and 44FPS. Performance was overall good, functionally tying with the GTX 1080 Ti; there was no meaningful difference between the 1080 Ti and the Radeon VII cards. The RTX 2080 Trio stretched its compute-targeted legs with a 65FPS AVG, leading stock Radeon VII by about 16%.

With a base overclock and a water cooling mod, noting again that the “2030MHz” you see here is just the setting, not the operating frequency, we see a framerate of 62FPS AVG. That’s an uplift of 10.5% over stock Radeon VII performance, and encroaches on stock RTX 2080 territory. Granted, you could overclock the 2080 as well and power would be lower, but this is closing-in in an impressive way.

The Radeon VII powerplay tables mod puts it at 65FPS AVG, giving us a disappointing improvement over the overclocked average performance of 4.2%. In plain terms, in more straight-forward and non-stat-mathy terms, that’s just 2-3FPS – it’s an invisible improvement, in other words, although an improvement nonetheless. The end result is that we tie with the RTX 2080 Trio, which isn’t a bad result, just not as big of an improvement as we’d expect for the power increase.

Let’s show a frametime performance plot to better illustrate the frame-to-frame interval differences. In this test, lower frametimes are better, but more consistent are better than lower. Testing is repeated in the same area and test variance is under 1FPS AVG per run, so this is very consistent and accurate as a test pattern.

The Radeon VII stock card ends up averaging closer to 19-20ms per frame, with the frame-to-frame interval deviation never greater than +/-2ms, on average. This is excellent consistency despite slower-than-60FPS framerate. The power mod and liquid cooling get our frametimes down to about 14-17ms on average, depending. Frame-to-frame interval variance does not meaningfully widen, so our overclock is considered stable for this testing.

At 1440p for Apex Legends, the Radeon VII stock card ran a baseline framerate of 106FPS AVG, which was significantly outdone by the overclocked variant’s 120FPS AVG. Just like last time, we see about a 13% increase in performance over baseline with the water-cooled OC test, and also like last time, we see very little difference with the powerplay mod. Unfortunately, with this test, the difference was within test variance. There was zero benefit from increased power consumption to the core. We believe this to be a limitation of core frequency, as opposed to the 4K results where we are more memory bandwidth limited as a result of the higher resolution. The differences don’t come out as strongly with a more core-limited scenario; at least, that’s our hypothesis for this one. TimeSpy Extreme’s earlier GT2 results reinforce this belief.

The end result is that the Radeon VII overclock ends up leading the RTX 2080 by about 14%, and is nearly tying the RTX 2080 Ti. Again, you cannot extrapolate this across all games. Unfortunately, some people will see this and tell everyone that Radeon VII is almost as good as the stock 2080 Ti, but that is true only in this instance. We just want to make sure everyone keeps their expectations within check of reality.

Sniper 4

Sniper Elite 4 with High settings and Dx12 gave us stock Radeon VII performance of about 85FPS AVG, with lows well-spaced behind. This positions Radeon VII as about tied with the RTX 2080 FE and just behind the GTX 1080 Ti. Overclocking and water cooling gave a significant uplift to 97FPS AVG, or 14.4% increased in performance, allowing the Radeon VII to outpace the stock 1080 Ti and 2080 FE, though overclocked results obviously reshuffle things again. The powermod only gives us another couple percent increase in performance, disappointingly, so the real story is in the uplift from cooling and a more basic overclock. Either way, the power mod does start to approach 2080 Ti stock performance, but doesn’t quite make it there and is still led by the stock 2080 Ti by about 9%.


We looked at more compute-intensive games with Apex, although using Dx11, and Sniper, using Dx12, so now it’s time to balance with a more traditionally developed game. GTA V at 4K and very high/ultra settings positions the Radeon VII at 51FPS AVG, with lows at 41 and 39FPS. This ranked it as just ahead of the 2070, only about 7%, while still being $200 more expensive than our tested 2070. The water cooling mod and an overclock improved Radeon VII performance to 56FPS AVG, an increase of about 9%, allowing it to get closer to the 61FPS of the stock RTX 2080 on our charts. Overclocking the 2080 didn’t get it much in this game, either, and only created a few percent gap versus the stock 2080.

The powerplay tables mod allowed Radeon VII to get to 57FPS AVG, showing an improvement consistent with the previous results at about 2-3% uplift. The net change is 11% versus the stock Radeon VII, with performance just under the RTX 2080 FE when the VII is pushed to our powerplay mod limits. It’s a very far distance from the stock 2080 Ti, which leads the Radeon VII powerplay mod by 55%. That’s a pretty hard counter to our previous two charts.

At 1440p, GTA V shows the stock Radeon VII at 99FPS AVG, leading the GTX 1080 FTW by about 6.6%. The overclocked and water-cooled Radeon VII places at 107.6FPS AVG, improving over stock performance by 9% again, with the powerplay mod showing similarly poor gains as seen in the Apex Legends 1440p benchmark. We think that most of the performance gains may be, once again, more resultant of the memory increase than the flimsy and unpredictable core increases.

F1 2018

For F1 2018 at 4K, the Radeon VII card performs at 73FPS AVG when stock versus the 2080’s 81FPS AVG, although we previously illustrated that the Radeon VII does seem to post stronger frametime performance in this particular title. Overclocking and water cooling the Radeon VII gets it up to 79.6FPS AVG, posting an increase of 9% again, with the powerplay mod putting it to 84FPS AVG and improving an additional 5% over the previous overclock. The net gain versus stock is 14.5%, landing it close to an overclocked 1080 Ti, but not quite passing it in average framerate – although the low frametime performance is superior, as we discussed in our previous review.

Far Cry 5

Far Cry 5 is the last one. At 4K, the Radeon VII stock card ran at 60FPS AVG, with the water-cooled overclock at 67.5FPS AVG, which is functionally tied with the 2080 Ti tested back on 417.35. We have not looked back at Far Cry 5 on the 2080 Ti since 417.35, but so far, the two are about equal with the overclock and water cooling on Radeon VII. Adding the power mod only gives us a couple percentage points of improvement, hitting 69FPS AVG and improving 15% over baseline stock, and adding water and an overclock to the 2080 Ti gets it to 82FPS AVG, leading the more power hungry Radeon VII by 18. 6%. This is without any BIOS flashes.


In our original baseline thermal testing, ignoring VRM thermals for a moment, we placed the full stock Radeon VII and its Hitachi graphite pad at a junction temperature of 108 degrees Celsius under load. As a reminder, junction temperature is the hottest of the 64 thermal sensors across the package, whereas GPU temperature is the edge temperature – literally the temperature at a cooler edge of the GPU – and is less useful. Radeon VII clocks based on junction, and its TjMax is 110 when stock. GPU edge temperature was about 80 degrees when stock.

Our water cooled mod under the same stock clock and voltage conditions ran a junction temperature approximately 39 degrees cooler than the stock temperatures, at about 68 to 70 degrees Celsius junction. The GPU edge temperature ended up about 40 degrees below stock as well, unsurprisingly, at about 40 degrees Celsius. Note that ambient temperature was controlled at 22 degrees Celsius for both tests and was logged every second with a thermocouple reader.


Moving on to frequency over time for this same test case, we see that, critically, performance is actually up versus the stock air-cooled card, and this is without any overclock settings applied. That means that boosting is utilizing the extra thermal headroom, which may also explain why we didn’t see reduced power consumption from leakage earlier – if it’s boosting clocks and voltages to meet the thermal headroom until hitting a power target, power consumption would remain the same. Our average frequency for the water cooled mod is about 1720 to 1750MHz, with some spikes to 1800MHz. The stock card averages closer to 1650MHz, allowing us a 70MHz to 100MHz average increase just from liquid cooling. That’s a very good result and is essentially a pre-overclock. Still, the water mod is more variable in frequency likely due to power limits, but it averages a higher result.

VRM Thermals

Finally, the newest GPU-Z rendition has given us software monitoring of the sensors inside of the power componentry on Radeon VII. Buildzoid’s video on our channel talks about these parts in more depth, but we can show the thermals of our mod here. Just to prove that you don’t need a baseplate on the VRM, and we validated this with hardware K-type thermocouples, the hottest component was a GPU VRM MOSFET, which plotted at about 50 degrees Celsius. That’s not over ambient or anything, that’s just straight 50C in a 22C ambient environment, so our delta is about 30 degrees. That’s damn good, particularly considering we have no baseplate and just positioned a Noctua fan to blow over the VRMs. We could even run this passively without the Noctua fan, although that wouldn’t be advisable for actual overclocking. Either way, Radeon VII’s VRM is efficient enough that it doesn’t run too hot. The GPU memory temperature plotted at about 47-48 degrees Celsius. We’ll just complicate the chart and throw the rest of the measurements up there. The memory VRM and SOC VRM temperatures ended up in the range of 35 to 44 degrees Celsius, ensuring that this card ran well within spec and better than stock even without a direct contact heatsink on the VRMs.

Conclusion: Radeon VII Water Cooling & Overclocking

Overclocking Radeon VII actually works now, sort of, and is far better than the initial driver release. Driver revision 19.2.3 (used for this testing) is far more usable for overclocking, although liquid cooling was ultimately required to enable us to uplift our frequencies to the levels we hit. It wouldn’t have been possible with the stock cooler, especially once we started applying powerplay registry mods to increase power to the card to ~500W. Our first liquid cooling solution, the Alphacool GPX block, was unfortunately uneven in its coldplate smoothness, and so we switched it to a modified Asetek mounting bracket and Thermaltake Floe 360 CLC, using some random fans (2x Gentle Typhoon and 1x Corsair Maglev) for cooling. This significantly lowered thermals from stock, as illustrated in our above charts, and allowed overclocking to much higher levels. Even stock performance improved, a result of more thermal headroom for boosting and reduced power leakage, freeing-up power for actually boosting the core. Note that we also tried pushing voltage up toward 1.3V, but did not see further scaling with the current mods installed.

We didn’t plot a thermal chart for the final overclock and powerplay mod, but junction temperature ended up pegged at 99 degrees Celsius. This is still below stock TjMax of 110 degrees, and well under the overclocking TjMax of 120 degrees. There’s a bit more room, but ultimately, we’d need to chill the radiator to leverage cold scale and further increase our clocks. Alternatively, some more experience (on our end) working with the overclocking software could help, as it does seem to still possess some strange bugs. One is that voltage won’t update without frequency also first updating, at which point that frequency can then be reverted. As we learn to deal with these particular quirks more competently, we can probably drive the clocks higher. The power offset mods also seem to stop working at some point. We can get the card to pull down more power, validated with clamps and software, but it seems to hit a fall-off point where power ceases its increase, despite further registry modifications to the power target limits. We’ll have to dig into this more later.

Finally, we did do some basic undervolting, but stopped at around ~0.94v. We’ll need to do more validation on this later as well.

As for whether we’d recommend going this route, the answer is mixed: We would recommend liquid cooling (particularly if you can get a cleaner solution than ours) and would recommend more powerful coolers, as there is some cold scale uplift even if only on the order of a ~20-degree reduction from stock. The VRMs ran perfectly fine without direct contact heatsinks, but a case with higher ambient, like 40 degrees, would make it worthwhile to add a fan directly over the FETs. This is negated if using a fuller coverage block or a proper “hybrid” approach, of course, but our fan+CLC approach worked very well for open air use. We wouldn’t recommend powerplay mods for anything beyond enthusiast tweaking or some overclocking fun, as we are uncertain of the long-term effects of such high power throughput. It’s possible that the core burns out sooner, so we’d advise caution for 24/7 use if intending to use some of these mods.

For now, though, we’re preparing to leave for Taiwan and China, and so any further tuning on Radeon VII must wait until we return.

The Wall: Stable overclocking of AMD Radeon VII with water block and chiller | igorsLAB

If you have always wanted to know what goes with a Radeon VII and the current drivers STABIL, if you overclock at maximum, this article with many details and the appropriate video is directly recommended…

First of all, I have to give all lovers of the well-groomed sensation a little damper – there is a lot going on and the air up is also plentiful – but you run, if you are honest with yourself and your card, then into a wall that only with much more Effort to scratch something, but not really to smash it. Nevertheless, today’s reading is worthwhile, because it also shows the possibilities and limitations in one.

Recognition number one: you don’t need extreme manipulations with the power-play tables (PPT), a more moderate PPT and a maximum limit of 60 to 70 are enough. And you have to play very cleverly with the beat and the tension if you want to achieve really stable and good results. The cards scatter extremely and mine was quite well subvolted, but in the other direction she likes less. That was the (somewhat bitter) realization number two.

And so you end up with knowledge number three, which tells me that good cooling is the be-all and end-all and that the infinite story with amD’s power supply seems to be open to the outside world, but internally in the firmware at Power Tune a small one , but has installed very effective Klaus-Kevin-Trap, because that a slightly raised voltage despite supposedly open limits causes a clock drop, was also somewhat new to me until then. At least in this intensity.

By the way, the 3DMark FireStrike uses a Core i9-7980XE with 4.8 GHz clock, the Aorus X299 Master from the last motherboard review, a whopping 32 GB Patriot 4 Viper with DDR4 4000 on all four modules, as well as the obligatory chiller from Alphacool and of course the one with the EKWB Vector delighted Radeon VII. The rest consists of en masse hose, 10 liters of water and Alphacool quick caps. After all, it is not more practical.

On the other hand, I benchmark the games on my usual test system with a Core i7-8700K, which I adapted at the speed of my US colleague’s system to stay comparable in the results and to ensure the exchange of data. But FireStrike-Punke can only be collected with fat hardware, since the mouse does not bite a thread.


The «I-have-the-longest-time-variant» and the bitter truth behind it

You get, at least for the aquarium, quite continuous «stable» through the 3DMark FireStrike, if you aim at the 2120 MHz. With the setting from the graphic below, I also manage a run with 2118 MHz – with hangings and strangles, but at least with every second or third attempt. Yes, you can specify with this and if you also «cheat» something, then there are already 33,300++ graphic points in it, which could imply, the map also ran stable with 150 MHz+.

But since you can’t play with such settings, nor can you use them in any way for something else, I just leave that. For the very brave, I also have the settings for the 2118 MHz here, but as i have already written: I am not suitable as the exhibition manager for the Gallery of Vanities. How to outwit the 3DMark, of course, I don’t write for understandable reasons, but you need a second monitor and a secure hand. The HMB2 runs at a whopping 1300 MHz, but the system frees in all games at some point, just not in the short FireStrike run.

If you leave it at this voltage and push the clock controller to 2150 MHz, then you can at least pull such exotic screenshots as this one from the menu of Witcher 3, where the voltage converters at over 2700 FPS and a power consumption for the entire map of approx. 400 watts, like loud hyperventilating cicadas screaming. You can give yourself exactly one thing, but of course this action does not really bring any added value. Am I the greatest now? Probably not.

But in order to be able to operate all other games and applications in a really stable way, you really have to go different and less spectacular ways. And that’s where we get back to the bottom of the facts, which is still a decent lifting platform.


Stable setting for 2050 to 2064 MHz

There’s something going on, after all. But since each card is a kind of unique and you never know whether you have caught a Golden Sample or a potato chip, you always have to test it very elaborately and test yourself to the «Wall». My rather mediocre card manages all this stable over all applications with these settings and final 1250 MHz clock on the HBM2 (Timings Auto):

This means that the 2050 to 2064 MHz are stable under real full load, depending on the application. In simpler games, the average value over the entire runtime was 2062 MHz, although there were even peaks up to over 2100 MHz. But these are short-term values and not averages, even if some You-Tubbie like to sell it differently. After all, I came up with more than 31,300 graphic points in the FireStrike and if you want to see it in detail, click here: https://www.3dmark.com/fs/18750492


Kevin-Klaus Käppi and a very serious video

I thought that if I work on the weekends and also have fun with our friends in the Tube, I could take some of the usual video protagonists a little bit. That’s why I shot my very serious video with some costumes, because it has to come across a little bit stylish. You also need a good skill amplifier and matching clothes. Then the records sizzle all by themselves. Yes., isso 😉

And for the attention-grabgers among you who see small speed cameras in the FireStrike – it’s exactly what I described above with YouTube-stable, which I referred to as the 2118 MHz profile. Flashing twice (despite successful run) means simply not uploading it, even if you only end up in 19th or 25th place. That dictates one at the end of decency. Nevertheless, you should watch the video in a quiet minute to understand my «suffering».


For the time after that, of course, I have all the benchmarks again in detail with individual graphics, Frame Times and variances on the next four pages. So as it should be. And I continue to wander between the worlds and now fight with text, image and additionally also the sound and my face.

Frequent Questions:

Is the Radeon VII good for mining?

Mining Profitability depends on the current market rates and which coin you are mining that you check using our mining profitability calculator on whattomine. At the time of writing this article the most profitable coin using Radeon VII is Ethereum and the profitability is $6.40 per day.

The Common Code 43

The Radeon VIIs are infamous for getting Code 43. Code 43 is when your GPU becomes unresponsive and does not work anymore. To avoid that handle your Radeon VIIs with extreme physical care. 
If you do get Code 43 then try to RMA your GPU, if you get it after the warranty expired then unfortunately there is not much to do.

More Information

Power Draw: Wattage draws for AMD Cards are not accurate in the software so you have to use a wall Watt meter to be able to measure the proper power draw.
Overclocks: Not all cards can run at the same settings so if you are unlucky and can’t run the settings provided then increment your memory clock down by 25 or increment your voltage up by 5 until you find a stable point.
Drivers: Try different drivers if you keep having trouble with instability after trying to troubleshoot your overclocks.

Today is the day AMD is set to release a new GPU into the market with its Radeon VII video card. Early rumors and ramblings from the AMD camp has this card pegged as a $700 (MSRP) card which is said to compete with NVIDIA’s RTX 2080 on the performance front, gaming at least. The card should do well in compute as the silicon it is cut from, the professional MI50/60 cards, are professional/server type of cards.

AMD Radeon VII

Sadly, we were not seeded a sample to review today, but hopefully soon we will be able to test it ourselves. In the meantime, we have compiled some specifications so our readers have some information about the cards from here as well as providing links to reviews of the card itself for some deep dives.

In the end, it appears the card is notably slower on average than the RTX 2080 AMD set out to compete against. There are some titles out there which seem to prefer AMD and the card is able to punch up a half weight class and reach/surpass the RTX 2080 but for the most part is looking up. As the resolution goes up, the HBM bandwidth helps shrink that gap.

Power use on these cards are a lot higher compared to the RTX 2080 as well (300W and 225W TDPs) so if being green is paramount in your decision, looking elsewhere will have to happen. Noise levels on this card compared to the RTX series FE cards was also higher in testing. Though it was rumored we wouldn’t see them, at least one AIC partner (Powercolor) showed off their cooling solutions so there will be other likely better options available down the road.

Performance and power use aside, the main concern with many on this GPU is AMD isn’t winning the price to performance metric as they have typically done on both the GPU and CPU side of the house. With a price coming in at $699, it is the same cost as the RTX 2080.

Radeon VII Front and Center

Where the card should shine compared to most RTX counterparts is on the compute front. The card is essentially an Instinct MI50/60 that is cut down. However, the MI50/MI60 have full compute abilities and this is cut back comparatively. Compute testing at Anandtech (though it didn’t have 2080Ti or RTX Titan) showed it easily bested the RTX 2080 in many tests. So if compute performance is a requirement, the Radeon VII does appear to be the best option for most situations here.

That said, competition is good, and we have a card which is notably quicker than Vega 64, and tickles the high-end market AMD is looking for while keeping compute a priority. Overall the Radeon VII feels like a card that was released to remind people there are other choices in the market but it didn’t seem to hit most user’s performance target (wants) nor pricing. Whether or not the AMD Radeon VII is worth it, is certainly up to the buyer however!

Where to start? With drivers!

The version of the driver sometimes makes a big difference to the performance of the graphics card. If you do not have AMD native drivers installed (with «AMD Catalyst Control AMD Catalyst Control Centr», or «Graphics Properties» — see Figure 1 below).

An article about programs and utilities for updating drivers —

Therefore, a simple advice, before you start setting up your video card, update the drivers (the link is given above): new functions and parameters may have appeared that will help optimize your hardware.

A note about the importance of firewood…

By the way, about 15 years ago, I had an ATI Radeon video card (I won’t name the exact model now). The bottom line is that in addition to the official drivers, there were “non-official” drivers — Omega Drivers (by the way, an excellent driver package).

So, by installing these drivers and turning on the maximum performance (in their settings), it was possible to significantly increase the performance of the video card!

In numbers… he was terribly slow (FPS: 27-30). After installing Omega Drivers and tweaking them, FPS went up to 36-40. Not much, but it allowed me to pass the level …

Note: there is no point in installing Omega Drivers now (this was not an advertisement, just a good example).

GPU-Z program: overclocking a video card safely and easily

GPU-Z program is considered by most experts as the safest option for overclocking a video card. The whole process of using it is covered in a step-by-step guide.

Step #1. Preparing the computer

First you need to work with the hardware. To do this, the power supply is checked — it is necessary to clarify whether it has enough power to use the program for overclocking an AMD video card. If its power is not enough, you will first need to replace the power supply, and only then carry out all the necessary manipulations.

Next, you will need to select a balanced or maximum power mode. You cannot run the power saving mode, because then the overclocking software for the AMD video card will not work properly.

Step #2. Choosing software

The best program for working with a video card is GPU Z, which is why it will be taken as the basis. But there are a lot of software options that can be used for overclocking. GPU-Z provides the user with all the necessary information about the graphics card without having to go inside the PC to find it. It’s better to load both GPU-Z and Afterburner at the same time.

Step #3. Tests for overclocking a video card

To make the best test for overclocking a video card, you can use the same GPU-Z. This process is required in order to get the current values. They are specified in the program immediately after it is launched.

The picture shows the standard and current frequency (bottom and top, respectively).

Step #4. Raising the frequency

Next, we will use a program for overclocking an AMD video card: MSI Afterburner. To safely overclock the video card, use only the 2 presented sliders, marked in the picture.

For safe use, first press the RESET button. Useful in case the video card has already been overclocked before. If everything is fine, then 100 units are added to the Core Clock column (no more!). If the utility turns off, then you need to remove 10 units and try again.

Step #5. Checking and testing

Now you need to run the program again to check the GPU-Z video card, and check the values. If everything is done correctly, then checking the video card through GPU-Z will show a complete match in the lines indicated earlier.

Please note! GPU-Z is a free program, it is distributed by the developer in accordance with a free license. Therefore, it looks very suspicious if some site offers an activated or cracked version of the product. Without activation, this utility will work normally, as well as provide the user with full access to all functionality. But even in cases with paid programs, downloading cracked versions is very dangerous, as well as looking for activators.

Also, the video card analysis program helps to monitor the state of the PC component, return it to factory settings if the resources are worn out. In this case, further use of the card with overclocking will lead to its complete failure.

I hope this article helped you safely overclock your AMD Radeon graphics card and achieve the desired result.

⇡ # Clock speeds, power consumption, temperature, overclocking

We still use Crysis 3 as a load to evaluate the «physical» parameters of the video card. Among the games of recent years, it can be considered a kind of GPU stress test — such a strong power consumption occurs with aggressive graphics quality settings. However, the Radeon VII normally supports quite high clock speeds in Crysis 3 — at the level of 1756 MHz, which is close to its «soft» limit of 1802 MHz.

Compared to the GPU on the Radeon RX Vega 64 board, the second generation Vega chip is 301 MHz faster. But something else is surprising: it turns out that the “seven” does not exhaust the power limit of 300 W and is even inferior in power consumption to its predecessor (286 versus 292 W).

But for the new cooling system, we have no compliments. AMD has promised that the Radeon VII will be quieter compared to the reference version of the Radeon RX Vega 64. Formally, this is true. But how is it that the difference in noise level in the gaming test between them is only 1 dBA, and in FurMark the novelty is even louder? After all, the Radeon VII has an open cooler with three axial fans, and all that Vega 64 has is a rather compact heatsink and a turbine fan, while both GPUs heat up to the same temperature (77 ° C according to the edge sensor). Of course, the cooling of the Radeon VII suffered to some extent due to the need to squeeze the heatsink into a closed dual-slot shroud. But for another manufacturer, this did not become an obstacle — look at the noise level of the overclocked GeForce RTX 2080 Founders Edition. Nothing to say about the water-cooled Radeon RX Vega 64, this is an unattainable ideal of silence for the rest of the test participants.

The GPU supply voltage at the top of the auto-acceleration curve for the Radeon VII is 1.078 V. Until we have access to other samples of the «seven», it is difficult to say whether such a voltage is actually needed for Vega 20 to work, but our copy in it is clearly not needs. The video card works stably at a voltage of 0.977, and due to the fact that Crysis 3 brings Radeon VII to the power limit, the frequencies from undervolting did not suffer and even slightly increased. And most importantly, the power consumption was thus reduced by 50 W, and the noise level of the Radeon VII became no worse than the Founders Edition accelerators. Let’s not exclude the factor of the so-called silicon lottery: who knows, maybe we got an extremely high-quality copy of Vega 20, and the spread of parameters in the early batches of 7-nanometer GPUs prompted AMD to leave a large supply voltage margin.

Be that as it may, the favorable ratio of frequency and voltage allows you to freely manipulate both parameters. So, for moderate overclocking, you can leave the GPU under the nominal voltage, increase the power reserve to the allowed 120% and specify the peak frequency of 1952 MHz (+150 MHz to the nominal value). But half-measures do not bring much benefit: for example, in Crysis 3 the GPU overclocked by only 96 MHz, and the power increase by 15 W made the Radeon VII cooler even louder.

Strictly speaking, because of the noisy CO, even the conservative overclocking of the «seven» has no practical meaning, but this is not a reason to stop the experiment. Our sample is capable of overclocking up to 2027 MHz, although for this we had to agree to the maximum allowable supply voltage of 1.218 V and an increase in power consumption to 340 watts. Oddly enough, the Radeon VII cooler can still handle the load at around 77°C under these conditions, but another limiting factor comes into play. Take a look at the table: the real frequency of the GPU with aggressive overclocking to 2027 MHz is less than with moderate overclocking, up to 1952 MHz. It looks like the graphics card just doesn’t have enough headroom.

Fortunately, not all tests heat up the GPU as much as Crysis 3: in other games, Radeon VII is quite capable of maintaining frequencies above 1900 MHz and making short-term surges beyond 2 GHz. However, we are again at a loss: how is it that the Radeon RX Vega 64, whose appetites are actually higher, allows a 50% increase in TDP, while the Radeon VII only 20%?

Four HBM2 stacks on a Vega 20 chip substrate with a nominal throughput of 2000 Mbps per pin allow overclocking up to 2400 Mbps. In the first tests of the «seven» we had to stop at 2300 Mbps — there was a suspicion that the memory was overheating at higher clock speeds. Like it or not, we do not know yet, because even WattMan hides the temperature and voltage of the HBM2 on the Radeon VII. But, apparently, the “window” overclocking technique also worked flawlessly with respect to VRAM.

Experienced overclockers consider the 3 DMark packages from Futuremark to be the benchmark tool for comparing graphics performance. These are sets of synthetic tests, each of which loads one or another structural block of the video subsystem. In total, there are 6 tests in the application, consisting of separate subtests — 2 physical (Physics and Combined) and 4 graphic. In the first subtests, the program loads mainly the processor, in the second — the video card.

3DMark is available in free and paid versions. Free — «Basic Edition», includes the same tests as paid ones, but does not allow you to change their parameters. The paid «Advanced Edition» ($24.95) gives access to changing parameters and allows you to run subtests separately, and the most complete and expensive one — «Professional» ($995), allows, among other things, to compare the quality of rendering (rendering) of individual frames.

The package version is selected depending on the version of DirectX installed on the computer. The latest today is 3DMark 11, which supports DirectX 11 and 12.

The testing process should be monitored visually. The appearance of various artifacts on the screen — ripples, «snow», loss of textures, as well as twitching and flickering of the picture, indicates overheating of the graphics processor (GPU) or memory, and in some cases — their malfunction. Freezes, reboots, blue screens of death are the result of video driver errors, power problems, overheating, or, again, a malfunction of the video card.

3DMark free version comparison results are displayed in the browser on the Futuremark website, not in the program itself. If this condition does not bother you, it is quite suitable for you to compare graphics performance before and after overclocking.

When running 3DMark 11 Basic Edition, select one of the two test options — « Benchmark tests only » (benchmark only) or « Full 3DMark 11 Experience » (full set), and click « Run 3DMark 11 «.

During the test video, the temperature of the GPU is displayed in the corner of the screen. If it quickly reaches 85-90 degrees, the cooling system is not working efficiently.

Other video card testing tools

During overclocking, you need to monitor the stability of the video in real conditions — in games and 3D applications that you use, as well as under stress — under artificial maximum load.

Stress tests using FurMark (Stability Test option) or OCCT (GPU 3D option). The latter tests not only the GPU, but also the video memory, and automatically fixes artifacts.

“GPU 3D” test settings are shown in the screenshot:

Monitor GPU temperature during check. Rising above 90-105 degrees indicates overclocking (if you have already started it) or lack of cooling.

Attention! The maximum allowable temperature of GPU NVIDIA is 90-105 degrees, AMD does not publish such data, but on average their critical level is 5-10 degrees lower.

A non-overclocked card should not warm up to the limit under stress. Otherwise, she will not have a margin for temperature rise after overclocking.

When and how to run tests

Before overclocking, run a benchmark test (to fix the initial video performance score) and an hour stress test to check the stability of its operation at maximum load.

After each step of increasing the frequencies, it is enough to run a stress test or a game for 5-10 minutes, monitoring the increase in GPU temperature. If everything goes well, and the heating does not reach the upper threshold, you can continue.

After overclocking, once again do a benchmark and final check for stability in real conditions — for example, run a demo version of your favorite 3D game for several hours. It is useful to drive and stress tests to control the temperature.

Firmware for AMD video cards

Before overclocking Radeon cards, they need to be flashed. The procedure for the firmware looks like this:

  • We start the miner in the stock value — to understand the effectiveness of overclocking.
  • Run ATIWinflash as Administrator.
  • Save the BIOS of the card (in .rom format). Please note: the app only sees 3 cards at a time.
  • Making copies of saved files. This is necessary so that you have default settings that you can return to if the process goes wrong.
  • Launch Polaris Bios Editor.
  • Open the .rom file of the card you will be flashing.
  • Change the Timing Strap indicators (copy the values ​​of VALUE 1500 and paste it into VALUE 1625, 1750, 2000), or accept the values ​​suggested by the program.
  • Save changes.
  • In ATIWinflash, click Load Image, select the file that was changed, select the desired card and click Program.

After flashing, «error 43» may appear. In this case, you need to download and install the Atikmdag patch — it should fix the problem. If the patch did not help, you need to return to the original settings by loading the saved file (item 3 of the list above).

That’s it — after that the card is flashed. This procedure is necessary in order to overclock the card normally. There are several ways to flash, they differ mainly only in the programs used. We have considered one of the schemes.

Downloading OverdriveNTool from a trusted resource

As of mid-February 2021, this is version 0.2.7 dated 11/09/2018, designed for AMD drivers versions 17.7.2 —

For newer AMD drivers, the developer has released beta version 0.2.8, which is also available for download.

Based on practical experience, at present the best drivers for mining on AMD video cards are 18.6.1, which must be installed according to the methodology outlined in the article “Proper installation of GPU drivers for mining”.

⇡#Game tests (3840 × 2160)

To successfully overclock Radeon VII with the current driver version, you need to follow one rule do not run 3D applications in full screen or frameless window . However, the windowed mode affects the frame rate, and most often negatively, so the rivals of the «seven» were put in the same conditions, and in order to quickly share the test results with you, we limited ourselves to 2160p.

At stock frequencies, the disposition between the Radeon VII and its main enemies — GeForce GTX 1080 Ti and GeForce RTX 2080 — has not changed at all. When comparing video cards that are so close in terms of overall performance and so different in GPU architecture, the result is largely determined by the preferences of individual applications. Among the eleven test games, one can distinguish frankly «green» (Assassin’s Creed Odyssey, Final Fantasy XV and GTA V) and frankly «red» projects (Strange Brigade and Wolfenstein II: The New Colossus).

The formally obsolete GeForce GTX 1080 Ti has become a convenient target for the Radeon VII. Let the average between them can put an equal sign, rivals exchanged heavy blows in separate games. But the only test in which the Radeon VII surpassed the GeForce RTX 2080 is the “red” Strange Brigade. In terms of average frame rate, the NVIDIA device has a 7% advantage.

Radeon RX Vega 64 Liquid Cooled and GeForce RTX 2080 Ti are the guests of honor in this test: 19 times faster than the first Radeon VII%, while the RTX 2080 Ti, on the other hand, is 32% faster.

The effect of Radeon VII overclocking directly depends on how high clock frequencies the power reserve allows to achieve in a particular game. On average, we are talking about an increase in performance by 8%, but there are also outstanding examples, such as, say, Assassin’s Creed Odyssey. In this benchmark, overclocking increased FPS by 18% — no wonder, because the increase in clock frequency is the maximum in it.

As for the NVIDIA reference video cards, the overclocking resource of the GeForce GTX 1080 Ti and RTX 2080 is about the same as that of the Radeon VII — about 7-8% in terms of average frame rate. As a result, overclocking didn’t help break the tie between the Radeon VII and the GTX 1080 Ti. But the RTX 2080 Founders Edition overclocks worse, and its advantage has been reduced to 6%.

By the way, according to the nominal frequencies of the GPU, the Radeon VII corresponds to the lower part of the range in which the GeForce GTX 1080 Ti operates, and in overclocking it is close to the RTX 2080. It turns out that the GCN architecture at comparable frequencies and the transistor budget of the GPU may well compete with Pascal and Turing, and only the specific performance per watt still limits AMD chips.

OverdriveNTool: how to overclock AMD GPU (step by step)

OverdriveNTool is used to overclock GPU supporting API AMD OverdriveN (290, 290x, 380, 380x, 390, 390x, Fury, Fury X, Nano, 6x, Vega, 5x, 5x, 4xx series ) and API Overdrive8 GPU (currently Radeon VII). This program came to replace WattTool , which does not work with the 17.7.2 driver version.

Which video cards should be overclocked

Not all video cards lend themselves well to overclocking, and not every video card is worth overclocking. Let’s say right away that you should not try to overclock mobile video cards (video cards in laptops). This is dangerous due to the increased risk of overheating and is ineffective from a performance point of view. That is, even if you manage to slightly overclock the video card in a laptop, the performance gain will be so small that it will be difficult to notice even in synthetic tests. Well, in real life, it will not be noticeable at all.

Also, don’t try to overclock budget desktop graphics cards. The reasons are the same as for mobile video cards. Budget video cards usually use a primitive cooling system, which increases the risk of overheating. And the possible performance gain is so small that there is no point in overclocking. Budget graphics cards include models from the NVIDIA GeForce GT series, NVIDIA GeForce GTS, AMD Radeon HD, AMD Radeon R5, as well as younger models from the AMD Radeon R7 line.

In addition, do not overclock video cards with passive cooling and video cards that previously had problems with cooling. In general, if your video card has a hot temper, then it is better to forget about overclocking.

Video cards with factory overclocking should be noted separately. They can be overclocked, but this must be done with extreme caution. Since such video cards already work on the verge of their capabilities.

February 16, 2019


February 7, AMD launched the Radeon VII graphics card. At the same time, the ban on the publication of information about the performance of the novelty fell and the first reviews appeared on the network.

The AMD Vega 20 graphics processor was originally planned to be used only in professional Radeon Instinct accelerators, whose price easily justifies the use of an advanced 7nm process technology and large amounts of HBM2 memory. However, in the case of the game card, the Reds had to make a lot of efforts to keep its cost at an acceptable level.

The Vega 20 die is manufactured by TSMC, contains 13.2 billion transistors and has an area of ​​331 mm². In the case of the AMD Radeon VII, it operates with 3840 stream processors, 240 texture units (TMUs), 64 render units (ROPs) and a 4096-bit memory bus. The nominal frequency of the GPU is from 1400 to 1750 MHz in boost mode. AMD also notes peaks up to 1800 MHz.

The 16 GB video buffer is stacked with four HBM2 stacks with an effective frequency of 2000 MHz, which achieves a throughput of 1 TB / s. According to AMD, an impressive amount of memory is one of the main advantages of the Radeon VII, and its full benefits should be revealed in new AAA projects when playing at 4K resolution.

In the reference version, AMD Radeon VII is made on a board with a (10 + 2)-phase power system, two 8-pin PCI-E Power connectors, HDMI and DisplayPort (x3) video outputs. Rated TDP — 300W.
The cooling system includes three 75mm fans and a heatsink consisting of an array of aluminum fins, a vapor chamber and five copper heatpipes. There is a reinforcement plate on the back of the card.

The gaming performance of the new AMD flagship, as promised at the time of the announcement, is approximately on par with the Nvidia GeForce RTX 2080. It all depends on the specific project. Curiously, as the resolution increases, Radeon VII often pulls ahead a little.

As for the overclocking potential of the new video card, it can only be measured after a fresh driver and updated versions of overclocking utilities become available. The power consumption of a system equipped with Radeon VII in gaming applications is 350-450 watts, and the graphics card itself accounts for about 250-300 watts.

Opportunities for overclocking the Radeon VII and analyzing its performance are currently very limited. The AMD WattMan utility allows you to log only the frequency of the GPU, RAM, GPU temperature and fan speed. And overclocking software — such as MSI Afterburner or GPU-Z — does not yet have access to this video card at all. But even in such conditions, it is still possible to experiment with Radeon VII, and quite fruitfully.

The curve connecting the voltage of the graphics core and its clock speed ends at 1802 MHz and 1.08 V (while the maximum voltage that can be set manually is 1.218 V) — Radeon VII works quite close to these parameters. So, under load in the 3DMark Time Spy stress test, after the GPU temperature stabilizes, the GPU frequency fluctuates around 1765 and reaches 1788 MHz. When it comes to power consumption, the Radeon VII isn’t doing nearly as badly as we feared. The power of the video card turned out to be 29The watts are lower compared to the Radeon RX Vega 64, although the energy efficiency of the latest NVIDIA chips still does not shine for AMD products, despite the nanometer advantage.

Standard settings



In the PowerTune algorithms, the new AMD flagship has one feature that radically changes the behavior of the cooling system and the GPU’s response to overheating: along with the GPU temperature at the edge sensor, which the API of past AMD video cards gives to monitoring programs, WattMan reports another value — Junction Temperature. This parameter is formed by 64 sensors scattered over the area of ​​the GPU and reflects the temperature in the hottest zone. Temperature measurements in different parts of the crystal are not new to Vega 20. Previous generation GPUs also have this feature, but before it was needed only for emergency shutdown of the chip in case of catastrophic overheating. Now it is Junction Temperature that signals the GPU that it is time to lower the clock speed or speed up the fans. The cooling system strives to keep the Junction Temperature within 100 ° C, accelerating the fans up to 2725 rpm, and when heated to 110 ° C, “throttling” already occurs — the GPU clock frequencies fall. The graphs clearly show that there is always a big difference between the Junction Temperature and the readings of the edge sensor: at stock Radeon VII settings, the edge sensor reports 74 °C, while the Junction Temperature reaches 106 °C at the same time.

As the creators of Radeon VII said, the distributed measurement that underlies the concept of Junction Temperature is not needed at all in order to limit overclocking (both using automatic and manual methods), but on the contrary, in order to use the slightest opportunity to raise clock frequencies during periods short-term cooling of the chip. On the other hand, this can be interpreted in such a way that the GPU always strives to approach a temperature value at which current leakage begins to threaten stable operation. To some extent, this seems to be true, because when overclocked by the user, the card really turned out to be very sensitive to cooling.

Our sample Radeon VII allows you to increase the maximum frequency of the GPU from the standard 1802 to 2002 MHz, and the effective frequency of the RAM from 2 to 2.3 GHz. To do this, we had to raise the supply voltage to 1.13 V and expand the power reserve by 20%, but the main thing is that stable operation is possible only at the maximum speed of the cooling fans (3850 rpm)! The «external» temperature of the GPU in this case is even lower than in normal mode (67 versus 74 ° C), but the Junction Temperature is exactly the same — it is obvious that everything depends on it.

Fortunately, with a more conservative overclocking of the Radeon VII, it is not necessary to think about heating. Without exceeding the nominal supply voltage of 1.08 V, we managed to raise the maximum GPU frequency to 1952 MHz, and under load it stabilized at 1914 MHz.
