Xeon Hacking and Overclocking X79/X99 [Beyond X58] - Page 64

Looking at the Cinebench screenshot:

http://i.ebayimg.com/images/g/3SsAAOSw-itXqFSf/s-l1600.jpg

I actually doubt it if makes sense to get this CPU. 1300 CB is just a little more than the result of a 4930K @ 4.5 GHz, 1200 CB, and the power consumption of 135W doesn't seem to be much lower than that of a 4930K @ 4.5 GHz. Or is thre a real difference in the power consumption? Because otherwise, what is the progress here, 1300 @ 135W and 1200 @a little bit more?

With all my systems, even the dual and quad socket servers I have, this is what I do. When folding it is best to leave one core free for each GPU to feed the GPU data.
If you have Hyperthread on leave 2 cores free per GPU
I do not fold with CPUs, I crunch BOINC with the CPUs and fold or crunch BOINC with the GPUs.
But even crunching with GPU I leave a core free to feed it data.

Granted I have Crossfire R9 290s instead of a Titan X, your low clock rate of 2.0/2.3 2 core turbo does hamper you.

Hi there

I agree,its low clocked ES chip and I sold it right now,I will be getting different one with higher clock and turbo speed,this chip has been great in rendering and I've been happy with performance,but pain has been in some 3D SW where you need good single core speed and there I've struggled with good performance plus IOPS issues with those ES chips I've encountered

Here is my older thread

http://forums.guru3d.com/showthread.php?t=407731

Here is my validation,only 103.56MHZ BCLK OC,this has been daily OC and for some benches I could go high as 105.5 BCLK,but this I think has been down to my previous cooling(H100i V2)

Hope this helps

Thanks,Jura

Turns out that these chips might be being fed more voltage than they need. I can't control the voltage in the MSI bios, but can through intel's utility.

When gaming turbo comes on and I see some cores spike to 2.6GHz while when all cores are loaded they stay fixed at this speed. This helps with bringing your temps and power requirements down some.

Got time today after work to pull together this small beast. E5-1620, Asrock x79 extreme6, 8gb ram (waiting for 16gb ECC), a 7950...

First test, undervolt at full clock under p95... I got stable up to about 1.06V. This chip has goddamn promise.

I don't dare use p95 anymore after I fried my motherboard with it..

The 1650 is in and it's much bigger than I thought! Coincidentally, I sold my 2600K today as well. I'm getting closer to a motherboard. If I got to choose, I'd probably go with the Gigabyte X79-UD3
post #637 of 1531
Well, 1650 is a quite good score... If in xmas season I see it in the 100 € range I might fall for it...

Besides, tried Cinebench R15, got a discretely good 664 PTS score (@ 4Ghz, HT ON)...




Tomorrow I'll reseat the heatsing with a better thermal paste and try to pull it a bit higher, if it does 4Ghz on 1.1V I expect good things on 1.25!

Any particular reason why trying to keep such a low voltage and lower clocks? Should be able to push it much farther. SB is good up to 1.4-1.45v.

Heat and power draw mostly.

The low voltage is intentional, before going into the overclock rage I checked what's the minimum voltage the cpu can run default - in this case it was 1.06-1.07V @ 3.6GHz, then a small overclock to 4GHz and check again, now I'm stable from ~1.125V.

I did this for two reasons, first the heatsink is seated down with some low quality thermal paste from another build - and sitting at 52°C full power under P95 -, i'm still waiting for some artic MX-2 due from amazon tomorrow. The other reason... Knowing that I can pull 4 GHz at just 1.1V, that means I can pull this cpu on air much higher, perhaps a 4.5-4.7Ghz without an extreme overvolt. This pc is used for both daily use and gaming, so long therm power draw is also to be kept in consideration.

What do you guys think about that QS E5 2667 v4? Is it any better than an X5650 @ 4 GHz? Can it compete with the 3930K / 4930K @ above 4 GHz? 1200 CB is kinda low. How good will it be at pushing strong GPU's like the 1060 or 1070 (ok I think 1070 is overkill for it given the low clock rate)?
