Overclocking i7 2600k on GA-Z68X-UD3P-B3

[lnpbgnr]

Could use some help overclocking an i7 2600k on a Gigabyte GA-Z68X-UD3P-B3. I have to use the Gigabyte utility in windows to get the cpu to 4.2 ghz. I go to 4.4 ghz, and it fails the stess test using Prime95.

Something else is weird. In CPUZ my vcore is 1.05 and the utility and the bios is saying vcore is 1.33.

Hi, I have exactly the same problem as you...I have the same hardware as you and I manage to run prime95 successfully with the utility boost to 4.2GHz...but when i dial it up to 4.4GHz manually...prime95 fails after around 30mins of stress test...and my CPU-Z also showing lower voltage...basically our problems are 100% identical...

Do you have any solutions for this yet??what values u put for Turbo Ration for Core 0, Core 1, Core 2 & Core 3 when set to 4.4GHz??

It's better to OC using bios rather than the utility. The cpu will go into a low power mode at idle which lowers the multipler to 16 and the vcore to ~1.

Hi k1114, thx for the advice...but i already know that...lol...
lnpbgnr...i already solve my problem...now running 4.5GHz stable...ran prime95 blend for 6 hrs without crashing / error / BSOD...^^

Thanks tupai1113 Ill give it a shot. You cooling your cpu with water?

 

[tupai1113]

nope...air cooling with CM V6GT...

Hi i know im a bit late here but just caught this thread and since i have the same motherboard im wondering if these settings would work for me too,i ran intel burn test with the same thing happening using the utility as you its worked once but failed second time i dont know why???

I am very wary of overclocking. I ran my new i7 2600k at 4.2 for 4 weeks using Easy tune6, then upped it to 4.5 manually, leaving all the other settings to the BIOS.Intel test showed all OK. After 2 weeks the motherboard packed up, taking the CPU with it. At no time did the temp go over 60c.

I got a warning from the Intel agents not to run at 4.5Ghz (how did they know)?
However, all parts were replaced,with a warning not to overclock.
