Other than that, it's pretty much the same.



I'm not sure if there is corruption. It's definitely possible. I mean, many people recommend leaving everything at stock until the entire software environment is set up - even when formatting and starting over with an overclock that's known to be stable. Although I personally have never taken it so far as to reverting back to stock from a known stable overclock just to format and start over. However I did wait to begin overclocking with my Sandy Bridge upgrade until I had everything set up and configured just the way I like it.
Maybe I'll just try one bump to the offset voltage when I get home.

What is the best way to format a hard drive before installing Windows? I did the format under "Disk options" with the Windows 7 install CD, but it does it so fast I'm assuming its just a "quick format". Maybe this has been causing me some problems since it wasn't a new hard drive?

One bump at a time is all is needed. For all we know, one more notch up might be all it takes. This core voltage is still very safe.

Well, even the format that takes a long time is the same as a quick format. The only difference is that the longer format includes an error-scan on the drive. Other than that, the format process itself is still just a quick process because it's essentially just a process of replacing the Master File Table with a fresh (blank) one in the specified format.

However, I think this problem is just caused by an unstable overclock. I mean, the stability got worse using 1.352V as opposed to 1.368V. So maybe all it need is either 1.376V or 1.384V.

Hopefully that's the case. It just seemed strange to me because it's fine under load, It's not fine when I'm trying to do normal tasks. I'm going to try bumping vcore some when I get home. I'll post back results. I'm worried about too much vcore though because I did try going for 4.8 GHz with more vcore but it was too hot (peaking at about 87c on some cores).

Prime95 Blend. Using HWMonitor to check. It would usually stay lower than that in the high 70's to low 80's but would occasionally peak higher.

Beware: Ultra High LLC and especially Extreme LLC will give the highest Vcore on heavy load, and give lesser Vcore on lighter load. So that could be the issue here.

I thought about that, but after I disabled C3 and C6 in the BIOS it seems in CPU-Z that the voltage is just pegged at 1.368 all the time now. Whether under load or not. I'll monitor this a little more when I get home.

Are you still using an Offset voltage?
