I have my machine clocked @ 8.5x400 and it's largeFFT stable (prime95 x64 v25.6) for 18 h 21 m at which point a rounding error occurred. Guess I'm wondering at what point (18h, 24h, 48h etc.) you call a system "stable"? I used to say 12 h was fine, but I over slept and it ran longer than I anticipated and gave the error. Here are the specifics on the system: Code: D.F.I. LP LT P35-TR2 (BIOS: LP35D317) Intel X3360 @ 8.5x400=3.40 GHz CPU VID=1.11875 SB 1.05V=1.070 NB Core=1.370 SB Core/CPU PLL=1.075 CPU VTT=1.280 Corsair Dominator DDR2-1066 (TWIN2X4096-8500C5DF) 2x 2Gb @ 5-5-5-15 @ 960 MHz (5:6) @ 2.100V Last fiddled with by graysky on 2008-05-02 at 20:37

If the system doesn't fail during this time, I consider it stable. Getting back to your specific case - your system is not prime stable, I would fiddle some more with voltages, and if that doesn't help lower the CPU frquency e.g. to 3.2GHz
