2500k and P8Z68-V - offset questions

astar0 · 17 Oct 2011 at 11:41

The VID on mine at 4.4ghz is 1.3611 but CPU-Z only shows 1.304 volts being used. This is only stable for 2 hours of Prime95 then core 2 fails.

In the bios I currently have CPU Voltage on AUTO and Offset + on AUTO. How do I up the volts to try get this completely stable? I tried setting Offset to 0.05 which in CPU-Z looked like it had added .05 volts but it crashed instantly when starting Prime95.

What am I doing wrong? And why is the VID different to the cpu volts on CPU-Z?

Any help would be greatly appreciated.

Thanks for replies.

I havent changed anything other than muitlipier to 44 and disabled PLL overvolt (some guides say to disable this and others dont).

My chip fails after 2 hours of prime so shouldnt i provide more volts rather than less?

Should I be changing the phase/LCC/duty and CPU compat also?

thanks - i will give this a go and report back

Changed all those options and set it - 0.005 offset. Its now stable at 4.4ghz. Current voltage is 1.344v and reaching a max temp of 72.

I will try lowering the offset one notch at a time to find out what volts it actually needs and to reduce the temp a little.

Thanks for your help.
