Short story is I keep getting errors with Prime95 when trying to figure out a new system of mine. I'm not actually overclocking anything yet, but I figured the OC forum would probably be the most knowledgeable on such issues.
Anyhow, the computer seems to be happy with the Small FFT's stress and has run for hours and hours with it with no errors, but on the blend test it gets a failure anywhere between 1 minute and 3 hours. Now I've tried a bunch of different things, and none of them seem to have any effect on the results at all.
ASUS P5E MB, C2Q Q9450 CPU, 4 GB Crucial Balistix RAM (2x 2GB)
1.) I've relaxed the timings on my RAM (down to 5-5-5-18 2T), and also even moved it down to 667 MHZ (even though its 800 MHZ RAM).
2.) I've upped the voltage on the CPU a decent amount (up to 1.35v core)
3.) I've upped the voltage on the North bridge from 1.25v to 1.31v
4.) I've upped the voltage on the RAM from 1.8 to 2.0v
None of these seems to have an effect at all on the stability of the system. It always passes the Small FFT, it always fails the blend. I'm wondering what might be the culprit. I have run Memtest86 for over 48 hours with my RAM set at (4-4-4-12 1T, 400Mhz) and it ran clean. I was thinking possibly dirty power from the PSU, but wondered why it wouldn't also fail the Small FFT test as well? I guess i'm a bit stumped as to what might be causing the rounding errors, and I don't have very many parts to swap out to play the "try it" game.
