Please comment on these settings for 3930k@4.9 24/7!!!!

post #1 of 10
Thread Starter 
My system:
Rampage IV Extreme
3930k C2
G-Skill 32GB 8GBx4 1600 cl10

Please comment on these setting for 24/7, I was able to pass IBT but not prime no matter what and then I think screw it I will just go with it since I can run stress test from AIDA64 and heaven DX11 at the same time, if anything goes wrong under daily usage I will just lower those settings. Also I am able to boot in windows with same setting for 100x 50 or 102x49 @5GHZ but just can't pass 3DMARK11 etc.

Also I can't get my ram to 1866 no matter what setting, even tried 1.65 vram and every digi power setting for ram. No wonder this 32GB kit is cheap.






Thank you for your time and input!!

The pictures look good to me, thats a nice overclock for a 6-core CPU. not passing Prime95 might raise a red flag, you can ignore it if you want but i would still not be toooo confident with 24/7 setup @ 4.9ghz. I mean it can work, sure... but not quite sure how stable its gonna be and running 100% without damage over time.

Thank you!!! Yeah I know it's not that good when it's not passing prime, but I tried many different settings except going over 1.4vcore which I really don't want to do for 24/7 so if I get any instabilities I will just tune it down a bit. When you say damage you mean just instability or corrupting OS and such? Thank you very much!

What's your VCCSA voltage at? over 1.2v for 24/7 can be very harmful on the C2 version of the 3930k. C1s can take a little more abuse, up to 1.4v 24/7. I see the offset is in the red and I'm wondering what the real load voltage is.

it's in the last pic 1.096-1.125 (min - max), because if I set it to auto it get pumped to like 1.17/1.18
if I set offset say 0.005 it gets 0.8 at default so thats why I am adding that much.
Actually do I need to add that much since I am not overclocking for my memory? Right now I am doing it at 1.1 to try to help maintaining my 4.9ghz stable. But if it can be lowered down would not hurt.
Thank you for your input!

Any time when i goo with OC "looks like good" soon or later i got problems with Windows! (bad system files etc.)
IMO: fills free to play with VTT/VCC -> as long as you are under 1.2V there is no harm but in some cases can help. Down clock memory to 1333 until you get fully stable processor . I will listen those recommendations that VTT and VCC should be equal (Try VCC on manual) . According what i found about your mobo looks like that you should be good around 1.15 V for those two voltages, so start from there and rise until you got what is needed (not over 1.2V). It was helped me to reach some stability. Once you get golden point then you can decide should you stay there or to lower.

I can get my Gskills to run at higher than rated speeds, It may take alot of tweaking, or you may have a weak stick. also i agree keep that vtt/vcc under 1.2v

Do you have the same kit as I do? Can you please share your setting please? Because I had to give a lot of vram and setting many options to high to post, cant even get into windows

Well its the luck of the draw really, im almost sure your sticks are the same, you just have more of them. CPU VCCSA 1.2v is what helped me. 1.65v on both banks of sticks.
