Specs:
COOLER MASTER Centurion 5 CAC
Antec earthwatts EA500
GIGABYTE GA-P35-DS3L
Q6600 GO, VID=1.25
Xigmatek HDT S1283 (replaced Arctic Freezer Pro)
Crucial Ballistix DDR2 800
BFG Tech GeForce 8800GTS (G92) 512MB
I got it stable at 3.3ghz@1.35vcore (ran Small FFT's for 8.5 hr's before I shut it off)
3.4ghz@1.4v seems okay. Ran Small FFT for 30 min and 3Dmark06. Will run this tonight to verify that it's stable.
But once I go to 3.45ghz or higher, it crashes usually within a few minutes regardless of vcore (I tried all the way up to 1.5v). It crashes like clockwork.
Could it be the FSB can't handle anything higher than ~380mhz? Do I need to tweak the FSB voltage?
I didn't list the temps but they're all fine. At 1.5v the cores are getting close to 70C, not great but not reason for crashing right? There is one strange thing with the core temps (even on stable OC). They'll heat up to a max value (example 65C), and then immediately fall ~7C. Sometimes they'll stay at the new low level for ~hr, sometimes they'll climb back up and fall again repeatedly. Only the 2 hottest cores do this. The other 2 will stay constant (+/- 1C).
With the Freezer Pro, the hottest cores were always 0 and 1.
With the Xigmatek, the hottest cores are always 0 and 3.
