Help me OC my 2600K - Page 2

post #11 of 106
Yeah I game in my spare time.
You can find out how high your voltage jumps in game using a program called HWmonitor. It will display the Min Max and Current voltage your CPU is/was at. Start that program before your game, play a few rounds than alt tab and check it wink.gif

I don't believe you will see max voltage in Crysis 2. I take it you are using LLC (Load Line Calibration), correct? My CPU temps in that game are about 67c with 1.48v under my air cooler which has similar performance with yours.

Given I wouldn't recommend running CPU Voltage past 1.45v, you won't see much performance increase going from 4.8 to 5ghz.

Yes, my LLC is set to Ultra (75%). Would you think removing a set of RAM from my mobo lower the voltage needed to run the 5ghz stable? I mean, it ran strong in Prime95 for an hour at 1.465, then out of nowhere a BSOD. Is there any way to lower the voltage for stability? I know it wasnt the temps that made it BSOD, they never even hit 80c.

It's possible that it's the ram, but there's no guarantees. Like I said I could not achieve 5Ghz with 4 sticks of ram, maybe for yor chip it's the same. You could try, what have you got to lose?

your temps at max are a little uncomfortable but its nothing to stress to much over. If mine hit 81c i start over.
I have an H100 with 4 ultra kaze fans, the temps at max reach 68c

i got mine stable at 1.44v
it could be that your ram isnt getting enough power.. but running prime95 that long then a crash sounds like it could be a power instability from your PSU
what is your PSU?

I apologize for all these questions, you've been a big help so far and I appreciate it.
Just one last question, do you know of any possible voltages or settings I could lower to see a stable 2600K at a lower cpu voltage @ the 5ghz I want? Yeah, I know i'm really pushing for this stable 5ghz thing but my OCD is screaming for me to make this work haha. Seeing as im going to be gaming pretty much all of the time, the voltages will be high as is, i'd like to have any little shortcut or trick or anything of that nature to have the lowest possible stable voltage for the cpu. If not, i'll try removing a set of ram but that's honestly the last thing I want to do cause I pretty much already wasted 70 bucks on it, might as well be in my rig looking pretty.

EDIT: @ F1ynn yes I have a push/pull config for my H100 on the top for my 800D, exhausting the air out of my case.

What are the BSOD's you get when it fails right now?
Could be you need to change the PLL Voltage and VCCIO. Also are you using Offset voltage or Manual voltage?

Hmm there's not really any shortcuts just small things that may or may not help.

You could try lowering CPU PLL to 1.7v and/or raiding VCCIO to 1.1v or 1.13v. Your memory controller is working hard to work with 4 sticks of RAM, VCCIO may help it a little bit.

I'm using manual voltage for now. I was just trying to see what voltage the 5GHz became stable before changing to offset so I knew how much to add or subtract from it.

My VCCSA, VCCIO, CPU PLL, PCH, PCH PLL, and NF200 are all set at auto. My CPU PLL is at 1.806v apparently, and the VCCIO switches back and forth from 1.118 to 1.111 to 1.105.

VCCSA @ .939/.946v (switches between two)
PCH @ 1.058v/1.065v (switches between two)
PCH PLL @ 1.058/1.065v (switches between two)
NF200 @ .007v

Set VCCIo to 1.15v
CPU Pll to 1.7v

Rerun the stress test

If it fails try more voltage to the CPU while keeping temps below 85c.

If not, keep it at 4.9Ghz, and call it a day. You will never notice the difference between 5 and 4.9ghz in everyday usage. Never.

Is it safe to keep testing voltages and getting BSOD's and trying other voltages to test stability? It's happened to me like 5 times today, so i'm just wondering. Also, I thought anything over 80c was frowned upon in Prime? It's actually 85c?
Thanks again though man. Really appreciate all your help.
