Good Overclocking Gone Bad; What Happened?

[n7]

Seems to me like motherboard is involved here.

It's definitely RAM/motherboard related though IMHO.

I'd look into a new board TBH...

That's 4 hours of running Windows and Folding@Home, and no problems. I'm going to try to overclock it a bit and see if it remains stable.

n7, I don't think it's RAM related, since my older, slower RAM exhibited the same problems repeatedly. I can believe it's the motherboard, but I am hesitant to call up Asus for a replacement without a smoking gun. Moving the video card doesn't seem like enough smoke.

20 hours of Memtest86+; I am feeling pretty confident now.

I can understand how the placement of the video card too close to the Northbridge chip would cause heating issues. I just don't understand why it took 4 months to show up!

You may want to remove your NB cooler and clean it, then reinstall using some high quality thermal compound.

in my rig I had the same problem (could run prime, superpi for some time without errors but it freezed sometimes) the solution was to raise LTD voltage, I dunno if it help you but worth a shot.

When I originally installed the NB fan, I did just that: I cleaned and prepared the surfaces with ArctiClean 1 and 2, and applied Arctic Silver 5.

At this point, I'm back to where I was previously, so I'm not inclined to do any more work. If the problem returns, this is the first thing I will try.
