I think I may have done it this time.
I got my Q6600 about 5 weeks ago.
Since then I've been running it at an even 1.50v @ 3.42GHz (though when I first got it it didn't require as many volts to go that fast -- but about a week later I had to up it from 1.47v to 1.50v to keep it stable).
With AC Pro 7 I hit MAX LOAD temps of 66C, but unless I'm stress testing, it never tops 61C while gaming and idles around 41C.
Anyway, I'm getting all kinds of crazy BSODs. So I put everything back on the mobo back to "auto." STill BSODs. So I ran P95 blend test (the one that stresses the memory b/c I thought it was the memory at firs). This came out fine - was stable for 2 hours.
Then I did "Max heat max power" which really pushes the CPU, and at stock speeds and stock voltage I had an error wihtin 5 minutes. I tried again after restarting, and same thing within 5 minutes. (same core failed each time too).
Is my CPU shot? If so, who do I call to see if Intel will warranty it (it was an OEM chip)? If they don't, well then it might be time for a Q9450.
Is there anything else it could be?
P.S. I have an SLACR G0
