1.39v solid for a P4 HT 3.2Giglyhertz 800MHz FSB 1MB L2 chip.
Now that I think about it, biostar does have a OC utility that can adjust voltages I believe, but its windows only. Of course it wont keep over a reset so I would not be able to run gentoo anymore..
I think it is CPU related, it seems to stay stable the longest under linux when I shut off F@H. Its been stable for about 4 hours now, which is one of the longest times its been usable.
Need a modded BIOS, lol.
