What are your Threadripper 1920/1950X overclocking results? : Amd

Formatting note:

Geez…what is up with the formatting in Reddit? It looks fine when I typed it out, but it removed all of my new-lines (where I hit «Enter» to create a new line) — especially where I put up my fan curve. Oh well…

My actual post:

I haven’t overclocked mine, but it’s somewhat unstable as is. I wonder if it’s my video cards, though (2x 1080 TI SLI), mobo, CPU, or memory.

I have a TR 1950X with GSkill 4x16GB 3200 MHz DIMMs CL14 on an Asus ROG Zenith Extreme. I just running at stock speeds, but with the memory at GSkill’s rated speeds. It was unstable until I set the memory voltage to 1.4 v (GSkill says it should be 1.35v).

With the NZXT Kraken X62, and full CPU load, I’m getting temps of 65c. Idles around 38c. CPU-Z says core voltage is at around 1.18v.

What is your results so far at stock?

Has anyone attempted to overclock yet? If so, what are your stable configuration (multiplier, memory speeds/timings, and voltages?)

Here’s my running log:

My fan curve (using CAM software with NZXT Kraken X62)

CPU — FAN %, PUMP %

75c — 100% fan, 100% pump

70c — 95% fan, 95% pump

65c — 85% fan, 90% pump

60c — 75% fan, 85% pump

55c — 65% fan, 75% pump

50c — 55% fan, 70% pump

45c — 45% fan, 65% pump

40c — 35% fan, 60% pump

35c — 25% fan, 60% pump

At 4. 0 GHz, I need more than 1.4v. I wasn’t about to find out exactly what voltage would be stable since temps were already soaring too high.

At 3.9 GHz, I was still unstable just past 1.35 v, so I didn’t want to go any higher (plus was STILL too hot).

I’m playing around at 3.8 GHz right now at 1.286v. Temps are currently 76c after 6 minutes of running cpuminer-opt 3.6.8 (xevan) on all threads.

8/23 (1am): It locked up. Now at 3.75 GHz at 1.264v. Temps are 74c after 10 minutes. UPDATE (7am): Staying around 73c after 6 hours.

I read that XFR disables past 3.7 GHz. I’m going to try for 3.7 GHz instead then. Brought voltage down to 1.243v (CPU-Z still says 1.264v though). Idle temp is still 38c. Looks like it’s geting up to 73c after 30 minutes.

8/23 (10am): About 3 hours into it. At work now, so I’m pleasantly surprised it’s still up for me to remote in! My home is set to 77F (typical room temp is actually 75F), but when I’m away it goes into Eco mode (85F). According to my thermostat, it’s 80F in the house, and CPU temps are now at 75c. Still using the CPU temp for the fan curve (not home to try out /u/jdorje suggestion of using the liquid temp), which means both fan and pump is running at 100%.

8/26: New fan/pump curve:

LIQUID TEMP — FAN %, PUMP %

55c — 100% fan, 100% pump

50c — 100% fan, 100% pump

45c — 100% fan, 100% pump

40c — 100% fan, 100% pump

35c — 25% fan, 60% pump

30c — 25% fan, 60% pump

25c — 25% fan, 60% pump

Also, I found out that the high temps were because of my case’s front face (NZXT S340 Elite). After taking it off, the temperature dropped to around 66c. Going to see if I can play with overclocking further now that the front face is off. Good to know for future builders looking for a case. It looks nice (I got the white tempered glass version), but it’s not good for front intake airflow.

Now that I know the cause of the high temps, I removed the front face cover and tried my hand at OCing again. I still wasn’t able to hit 4 GHz (even at 1.41v, it was crashing immediately).

At 3.9 GHz at 1.4v, it would still crash after about 18 minutes, while temps soared to around 83c.

As of now, I’m at 3.8 GHz at 1.373v at the 20 minute mark and still going. Temps is now hovering around 76c.

Dropped back down to 3.7 GHz at 1.35v and temps hover around 73c.

I’m going to stick with the stock 3.4 GHz now with the front cover back on (it gets up to 60c). At least I know where my clocks/voltages are if I ever get a better cooler or decide to change the case. For now, if I feel the need to OC, I can always go up to 3.8 GHz and take the cover off for those special times I need the extra performance.

I would like to upgrade to a AIO that a cold plate that covers the entire package in the future, though. I heard the Enermax not only does that, but also has a very beefy radiator (not easily crushed).

Threadripper 1950X Overclocking and RAM setup (My experience so far + Your Speeds? + Suggestions?) : realAMD

Warning — I was in a ‘typing mood’ and this post got longer than I intended. #).

After a little tweaking, I found the best clock for the CPU at the moment, is bang on 4GHz with a lazy multiplier tweak and a little extra voltage. Set to 1.4125v, the system will dance between 1.3952v and 1.4175v under difference loads. I could get 4025MHz and 4050MHz stable with more voltage, but it started getting warm pretty quickly (59C), and the power consumption added for a 0.5% to 1.5% increase in performance just wasn’t worth it. I may revisit higher clocks on the CPU at some point, but for now this is a nice balance of extra grunt (up to 22% on blender vs stock speeds) and power consumption.

The jump from 3.7GHz (4.1GHz single core boost) up to 4GHz across the board, added around 5-10W to it’s idle consumption, and a spicy 136W to it’s stock 179W full load consumption — maxing at 315W under load. Luckily It’s plumbed into 4 radiators and the block used is a EK Monoblock to keep the power delivery components cool also.

The RAM however, was not so easy.

First off, 128GB is an obscene amount of memory so before you ask what I need it for — the answer is that I don’t need it at all. I did however, want it. Options of playing with RAM Disks, VMs, massive calculations or algorithm, or simply coping with run-away RAM leaks half way through an important task, is why it’s there. I was also set on using DDR4 as a RAMCache for the OS drive — something I’ve done in the past — and this alone takes 24GB up but gives some nice results. This can be turned on and off pretty easily too, so it’s not like that 24GB is dedicated to this only. If I genuinely needed more for a task, it can be disabled and used as system RAM again.

24GB RAM Cache on an M.2 SSD

Even the first boot with this RAM was a sod. I got an infinite boot loop, and after testing a few things — out came the memory. The system booted with one stick, so I slowly added them all until it was happy with all 8 sticks of 16GB were installed. For a good while, I ran the machine at 2600MHz because anything above that started causing a couple of issues, and I was excited to get playing.

After several days of testing and tweaking, I found that 2866MHz was about as fast as I was going to get without having either ridiculously loose timings, or a load of power going through the RAM. Up to that point little extra voltage was needed above the stock 1.22v for lower speeds, and timings were good, but I’m still yet to get 2933MHz stable even with timings such as 20-20-20-40 and at 1.38v. I know many run their high speed RAM at 1.4v, and I’ve seen several threads with hefty kits like mine running at 1.5v daily, but I’m not too happy about doing that. The kit was a pretty penny and I’m not ready to pop 1.5v into it just yet. Pushing to 1.4v should be fine, so that’s something I’ll play with at a later date. To get the speed and timings I have now, it took 1.3675v, and 1.165v on the SoC. At idle, these sit at 1.3516v and 1.1554v respectively.

Timings were easier, and have impressed me so far. Over the last two days I’ve dropped timings down little by little and then running several tests for stability, and today I’ve landed at 14-14-14-32-64 with Command Rate 1T. This is way under say, what Vengeance kits often ship at, even on 32GB, let alone 128GB. So I’m pretty happy with that. Several passes of MemTest and a few hours of Prime95 (round off checking) and all okay. I had one foul POST, so I increased the RAM Starting Voltage to 1.4v just so it’s got all it needs to kick off, then it’ll drop back down once booted. So far, so good.

Tightening the timings certainly gives benefit to the CPU. You can see below, in CineBench I can almost hit the same results with 4GHz as I was getting with 4.05GHz, with memory at the same speed — but better timings. The lowest result with 4GHz (#7) was with 2866MHz set to 15-15-15-36-66 I believe. Tightening them up gave me just shy of 5% increase (#4). Take this with a little pinch of salt however. I’ve tried to get the system running as «idle» as possible for the testing, but I’ve been using the machine for a good month now so there’s bits and bobs in the background that may affect the scores. Each of the scores below were run about 3-4 times to rule out flukes, and the top score being saved. It should be a fairly good representation of the OC benefits.

I’m sure there’s still more to get from the memory and CPU, but it’s getting close now. Minor changes to voltages or speeds quickly create instabilities.

So now. The big question — How did I do?

Let me know your setups and speeds. Bench results etc. I’ve overclocked and tweaked machines for a long time, but Ryzen is a bit of a unique one, and I’ve certainly never tried playing with so many cores or capacity of RAM before. I’d love to see more results on here from other Ryzen users (first gen, second, and TR4), and see where we’re getting these chips to. If you have a system similar, I’d also love to see where you’re at with it.

If anyone’s suggestions on where I should go from here also, please let me know. Suggestions for better speeds from the chip or memory. I feel there’s more there, but I fear it’s only going to be at the cost of big power for small results. Every now and then though, there’s little options or toggles which make a small difference, but difference all the same. The Zenith’s BIOS is extensive, and I’m sure there will be things I’ve missed.

Thanks for reading.

Couldn’t be more pleased with the chip at the moment.

It’s time to move on to tests that should better parallel the load.

Advanced Video Format Encoding Test puts AMD fans a little at ease. Here we see an even better picture than before in the «synthetics»: in the normal mode, the Threadripper 1950X, albeit minimally, is ahead of the «stock» i9-7900X! True, in overclocking, due to the better frequency potential, it still comes out a little ahead. But a start has been made!

However, the potential of 16 cores and 32 threads should be most revealed in rendering. Let’s see:

This is AMD Ryzen Threadripper 1950X high point! These are the tasks where its sixteen cores show their full potential. Neither the best single-core performance of the Core i9 helps-7900X, which can be seen in Cinebench, nor its best overclocking potential, as a result, the hero of the review is always ahead.

And so that AMD fans do not relax, we left PiFast at the end of the two-dimensional tests:

In tests where single-threaded performance is important, it can be seen that AMD Ryzen processors are 20-30% lower than modern Core processors. However, that’s why they have more cores.

But if, as we have seen, not all of them are still used even in «counting» problems, then what will happen in three-dimensional ones? They are next in line: 3D tests and games.

The very first 3D test shows the same standard picture: the overclocked performance of the 1950X almost reaches the level of the 7900X in normal mode. And overclocking allows the latter to come off a bit again. The same happens in the CPU test. And here again, let’s not fail to kick «Game mode». If it fails in 3D tests, why is it needed at all?

But in the not new Unigine Heaven, the performance of one core is clearly more important. And here, surprisingly, the Ryzen Threadripper cores perform very well. As in the case with the previous synthetic test, it can be argued that in general this is the level of the top thousand-dollar Intel processor.

However, in 2D games it was in real applications that AMD’s new product had the hardest time. What will happen in real 3D games? All games were tested at 19 resolution20x1080 with the maximum quality profile available in the settings.
