Stable or Not?

I currently have my system overclocked to 2.64GHZ from the original 2.4GHZ that it came at. I have memory set at 220MHZ and it is MemTest86 Stable on Test 5 and 8 for 3 hours each, no errors. I have run every iteration of SuperPI (16K - 32M) and they all finish with no errors, but the second I start Prime95 it fails. I have been able to play Battlefield 2 demo for 2+ hours, no crashing, no problems. I am confused about what is going on here. Prime won't even run for more than 10 seconds before it crashes, but everything else seems to be stable. What do I trust?

Thanks.
 
Scale it back just 10mhz and see if Prime will finish. If it does then your just at the edge of your overclock. If it doesnt maybe try reinstalling prime.
 
I'd consider it unstable. In my experience, if it fails Prime 95 eventually you'll experience a crash in something else you're doing. With my Winchester, it would run Prime 95 for about 4 hours, and then fail. I could play games and whatnot without trouble, but every now and then when logging into a Windows user account, the computer would lock up and I'd have to reset it. Reducing my overclock by about 20 or 30 MHz solved that issue.
 
exactly true. i ran my cpu without priming it, but it ran games and everything fine. one day, it crashed in the middle of a game and pissed me off. i had to reduce it by 50mhz

Scale back the memory too to 210.

The reason I said 10mhz is because he is stable in games and 10 x multiplier is around 100mhz.

Your only doing this to see if you can get through prime stable. Also reload it for the heck of it.
 
Did you remember to drop your HTT multiplier by 1 when you started overclocking? Your hypertransport would be 80-100mhz over specification (80 if an Nforce4 vanilla is 800mhz hypertransport, 100 if it's 1000mhz hypertransport, I can't remember which) at your bus speed and that could be a cause as well.

The machine is Prime stable at 2520 and I did put HTT at 4X. Well, guess I need a new chip!
120 MHZ OC is pathetic!
 
How much are you going to sell it for ? PM me so as not to break the rules. Thats OK isn;t it ?
