This is driving me nuts. I just got done running Orthos for 6 hours. Stopped it to see if I could get a little more aggressive. I bring up uGuru and the computer locks up on me (about 20 secs after quitting Orthos). What is going on here?!?!?!?! It happened a few times before but I blew it off as tight memory timings or not enough vcore, vmem, etc. I tried to set everything up so I could eliminate those as problems:

VCore 1.44 in bios. 1.37 in CPUz
FSB 455
Max Temp after running Orthos for 6 hours, 63c (was usually around 58-61)
Memory: 5-5-5-18 at 2.2v
I also had MCH and CPU VTT up a notch or 2

Any ideas???? Please help!

Did you run both Prime95's small FFT's test for 8hours and blend test for 12hours? Blend test stresses the ram, and if the ram is unstable, you can crash easily.

Another possibility is that you enabled some option that gets rid of vdroop and/or voffset in the bios. Disable that, it may be the cause.

That makes sense, but wouldn't it crash DURING the Prime95's test? That's the thing I don't understand... it only crashes after I've quit the test.

Sometimes after you finish doing something cpu intensive, the voltage might spike up some way or another, and vdroop is meant to prevent that from happening. If the voltage spike passes the VID, you crash.

Ahh, that makes sense. Could it spike past where it's set in bios? Because I've only gone as high as 1.48 in bios (1.37 CPUz after vdroop).

Any ideas on what setting in bios I might need to change?

Yes it's possible that your cpu is going pass the VID, thus causing instabilities. Read through your motherboard manual and check to see if you have any option that tampers with Vdroop and turn it off.
