Stable or not?
Asus P5B, Q9400, Xigmatek Dark Knight HSF, 2x2GB OCZ Titanium DDR2-800, nVidia 8600GTS w/factory OC, Antec Truepower 2.0 430.
Multiplier: 8x, FSB: 400MHz
Vcore: 1.3125v reported by CPU-Z as 1.280v idle and 1.216v under load
FSB Term: 1.4v, NB: 1.25v, SB: 1.5v, ICH: 1.057v
RAM: 2.1v, 4-4-4-15 w/default settings for the rest
Core temps: 43-45C under load, 28-39C idle, 22C ambient
I ran Prime95 blend for 25 hours, 12 mins before it found an error on one core. Would you consider that stable? I was only going to run it for 24 hours but I didn't get home until 26.5 hours. It failed on core 3 (or the 4th one) which is also the core that always idles at 39C while the others are below 33C. What do you guys think?
EDIT:
I just ran a small FFU test for a few hours and the same core (#4) failed at 2 hours, 43 mins. I also seem to have an issue with the vcore voltage in the BIOS. Every time I look at the BIOS it goes back to Auto and I can't change it unless I hit enter, choose auto, save changes and exit, and enter the BIOS again. When I can't change it the text is yellow as well. I'm worried that if I just restart it without changing it back to what I had it set to it'll go back to auto. The last time I booted it up on auto at 3.2GHz I saw it over 1.5v in Windows.
