Windows 8 possibly more sensitive to overclocks? I seem to have some BSOD issues.

[JM Popaleetus]

Hey all. Was hoping to get some thoughts on this. My current overclocks and setup can be found in my signature. These settings were 100% 24/7 IntelBurnTest, etc. stable in Windows 7. Temperatures are also in the 30-40's.

However, now on Windows 8 (which I do love, so I'd prefer to stay on it) I'm getting the following random BSODS: "PFN_LIST_CORRUPT" and "PAGE_FAULT_IN_NONPAGED_AREA". These BSODs are however VERY infrequent and rare. I've had maybe 5 total since I installed Windows 8 around it's launch.

I'm wondering if I should try cranking my voltages up a single notch to 1.381 vCore, 1.435 QPI, and 1.220 or Auto for IOH (currently 1.20)?

I have already tried MemTest86+ and it completed 7 full passes with zero errors. I have not tried running IBT or OCCT on Win8.

I'm honestly not sure which of these stamps (Bug Check Code?) I'm supposed to be cross-referencing against http://www.overclock.net/t/940091/bsod-codes-when-ocing-must-have-info .

Looks like ntsokrnl.exe is the issue though.

None here

I even installed Windows 8 overclocked. No issues here.

You may have actually been on the hairy-edge of stability with your old setup and the new windows uses certain instructions from the ISA that the old windows didn't use or didn't use as often, so now you are finding that your old setup was probably unstable all along for those specific intructions. (which wasn't a problem before because you weren't using them in a critical app anyways)

Interesting.

I'm going to switch my IOH to Auto per HardOCP's recommendation from their original review of my motherboard. Their review even suggests to keep QTT and vCore at Auto. From experience though, I prefer setting at least the vCore as Auto tends to keep it hot.

However, thoughts as to whether I should try upping my QTT or vCore first? Or just go up a notch with both? Perhaps set QTT to Auto and manually adjust vCore up?

I will be going to test stability with another round of IBT under Windows 8.

If it were me the first thing I would do is start reducing my clockspeeds while leaving everything else alone (same Vcore, etc) until I find out what clockspeed the computer is stable at. Then that would give me an idea of how large an instability gulf I have on my hands.

Then start increasing your clocks while increasing Vcore, same as you would for any new system when dialing in a stable OC.

Work from a place you know is stable. Don't start out in the middle of no-man's land looking in every direction for some sense of direction.

Sounds good. Thank you for your help.

Looks like I have a weekend project on my hands.
