I'm currently running an E6400 and P5B Deluxe, and so far I'm extremely impressed with the overclocking potential of my E6400. I have it undervolted to 1.1v, and even then it's still going strong at 2.712 Ghz (339x8). I didn't expect it to overclock that much at such a low voltage. I have a feeling I could push it even more without raising the vcore.
However, even though I'm able to run dual prime with no problems for 10 hours (or more, I didn't have the patience to run it for longer) at that speed, I get a "not exact in round" error in SuperPi 32M within a few seconds. I'm running my Corsair memory rated at DDR2 800 5-5-5-12 at DDR2 678 5-6-6-18, so I'm fairly sure sure my memory's not the problem. All voltages other than vcore (1.1v) and vdimm (1.9v) are on auto.
So what's my problem? I know it isn't the CPU or the memory. Does small FFT prime test motherboard FSB for stability?
