Hi, this is my first post so bear with me.
I have a core i7 920 running @ 3.9 ghz on a gigabyte ud5 mobo. It has bios F6a. I have a sunbeam core contact freezer as a heatsink.
The OC specs are as following
195 bclk
Vcore 1.375v
QPI 1.360v
DRAM 1.64v
QPI multi is 36x
Memory spd multi is 8x
Uncore is 16x
Load Line calibration is enabled
All power saving functions are off, as well as turbo mode. HT is still on.
So the strange thing is, when I run Prime 95 within 5 minutes of startup, on small FFT, I am able to run it for 10 hours or more. But once I turn it off, or never turn it on at all, it just reboots after about 10 minutes. It also crashes when i click the start button on 3d mark vantage.
Is there some sort of power saving feature that is screwing me up? Or is it just bad hardware? I can run at stock just fine.
Thanks for all your help and I apologize if i posted it in the wrong forum.
