What a Difference 0.1 V Can Make

I meant to write about this last week. My main amd64 box crashed the other week and managed to clear the BIOS settings along with it. It is a socket 754 Gigabyte board that I have never had too much luck with. They limit the RAM to DDR333 instead of DDR400 as they incorrectly quote AMD specs - I have built other systems using the same two sticks of double sided 512 MB DDR400 Corsair RAM! Anyway, reset all the settings I could remember, and it all seemed OK. Then kept getting random crashes and segfaults and thought it was a bad kernel or something. Played with all sorts of settings, and even rebooted into Gentoo on another partition. Ram memtest86+ and it all passed just fine. At the point of pullling my hair out I took a breather and then thought may be upping the RAM voltage would help. Did that and I have not had a single crash/segfault since! As I said what a difference 0.1 V can make Lost half a week messing about with it, but got it sorted in the end…
