Hey,
So I checked the ground and it was not making great contact, i moved it to the plate, played some CSS and alot of the background hum and pop was gone, but not perfect... I then went to play some WoW, got in our 25 man ulduar raid and with in 3 minutes when the action started, bam.. Major crash. I wanted to break the thing.
I went back into the bios and made some changes:
Vdimm=1.54 volts (1.6 measured, this was my orignal setting, memtest pass, but still had crashes)
Vcore=1.35 volts (1.36 measured, intel says this is max for this chip?)
Vtt=1.30 volts (1.32 measured, was auto at 1.12v)
NB=1.40
SB=1.50
disabled the spread spectrum. One thing to note, is before i changed the ground, Vcore at 1.24 volts (bois setting) actually measured 1.32Volts actual. This time the bios setting actually measured super close. I ran prime95 11+ hours not a single crash.. Ran a 25 man raid last night and not a single crash..
I suspect like many others have noted ,is that Vtt is extremly important on this board, especially for quad cores and the auto setting is just not right at all, at least for my board. My guess at this point is that I could drop the Vcore a bit lower to get the temps down, so going to test that. At 1.36Volts, the temps never got above 55c and pretty much just hovered around 50c on all 4 cores, MCP at around 58c average.
