I don’t need to repeat what so many review sites already stated. This is definitely a great processor on a powerful platform. Paired with the right motherboard and memory, you can push this upward of 5GHz easy.

What clocks/settings have you gotten?
It’s hard selling PC parts where I’m at and I plan on getting a new motherboard for better GPU-spacing and I also plan on recycling my CPU so with my old x79 motherboard (sabertooth, what’s yours?) I want to see what kind of clocks you can get on it as I might make a smaller (mid tower) atx build with this CPU.
Thanks .

Right now I’m running stock. I OC’d my DDR3 2000 to 2133. I don’t have a need to go much faster. Motherboard is an Asrock X79 Extreme6/GB. Asrock boards have excellent spacing between the PCIE x16 slots. For your six-core, I suggest the x79 Extreme9, x79 Extreme11, X79 Fatal1ty Professional.

Entry into X79
review by amdkillsintel
A great way to get into the X79 chipset for cheap.Has a limited multiplier (37-44x)so you have to overclock it the old way if you want to go beyond the range, by tweaking the straps (kinda like the FSB), but leaves the BClock (which controls the other hardware untouched). It overclocks well, I was able to get my chip up to 5.0Ghz under water. It’s a great chip if you want to reap the benefits of X79 and also be on a socket that will have some longevity.
The only cons are: it uses more juice than the i7 2600K and can be a little slower clock per clock (check the review sites for more info). But, I don’t think anyone will notice the difference.
| Pros | Cons |
|---|---|
| Fast, fairly cheap, overclocks well |

Great budget LGA 2011 CPU!
review by srice4904
Having never overclocked on LGA 2011, it was surprisingly easy. I looked to my good friends here at www.Overclock.net for overclocking advice and it was easy as pie
I don’t know of others experience with this processor overclocked but with a simple BCLK ajustment of +20 I reached 4.4 ghz stable @ 1.33 vcore with everything set on auto! Granted I would be able to get that down with some tweaking but IMO 1.33 under water with max core temps of 55c whilst stress testing is just fine
Paired with my Sabertooth x79 and 2 x Sapphire 290x’s in crossfire the performance is simply amazing! I would recommend this to anyone who wants to run multi gpu’s or anyone with a LGA 2011 platform.
With the overclocking ability of this inexpensive cpu the next step up would be to get a hexacore but with the added price and the fact that for us gamers the extra cores don’t help much except in benckmarks, it is a down the road upgrade.
| Pros | Cons |
|---|---|
| Easily overclocked, price, preformance | Semi-Locked multi |

Gaming
To see if Intel Core i7-3820 is good for gaming, we checked what popular, new, and upcoming PC games will run on it:
Specifications Intel Core i7-3820 Sandy Bridge E: tests, competitors, price
- 0003 Core i7-3820
Core i7-3820 processor
Quantity of cores — 4, produced by 32 nm process technology, Sandy Bridge E architecture. Thanks to Hyper-Threading technology, the number of threads is 8, which increases the performance of multi-threaded applications and games.
The base frequency of Core i7-3820 cores is 3.6 GHz. Please note that the Intel Core i7-3820 cooler must cool processors with a TDP of at least 130W at stock frequencies. When overclocked, the requirements increase.

Intel Core i7-3820 benchmarks
Speed in games
Performance in games and similar applications, according to our tests.
The performance of 4 cores, if any, and performance per core has the greatest impact on the result, since most games do not fully use more than 4 cores.
The speed of caches and working with RAM is also important.
Speed in office use
Performance in everyday work such as browsers and office applications.
The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.
Similarly, many professional applications such as various CAD programs ignore multi-threaded performance.
Speed in heavy applications
Performance in resource-intensive tasks loading a maximum of 8 cores.
The performance of all cores and their number has the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.
At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.
Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values corresponding to the processor.

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.
We believe that a minimum of 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.
Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks. Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance.
When choosing a processor to work with, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.
Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum).
A typical result is shown in the middle, the more filled in the color bar, the better the average result among all tested systems.

Benchmarks
Benchmarks were run on stock hardware, that is, without overclocking and with factory settings. Therefore, on overclocked systems, the points can noticeably differ upwards. Also, small performance changes may be due to the BIOS version.

Game Test
90 020 FPS measured by us in popular games on Intel Core i7-3820 and system requirements.
Please note that the official requirements of developers in games do not always match the data of real tests. Also, the result is strongly influenced by the overclocking of the system and the graphic settings in the game. We test at high settings in FullHD resolution to get numbers close to real gameplay.
Now there are 29 games in our database. On average, in all gaming tests, the processor scored 51.4 points out of 100, where 100 is the fastest gaming processor to date.
