I had to pump up the voltage and break it in. It crashed for a while but after a few months the problem up and disappeared. Note that it seems gigabyte cheaps out on the voltage there, because I can't even get my ram to 2.2v like it says on the chip. only 2.1v... It's running fine these days though.
i asked kingston if the voltage was too low and they said that a new board like that should have no problem running at 1.8, which is common for 800 Mhz ddr2 ? i am not a ram expert, i havent followed hardware in a while.
and to test, i drove to my brothers house and swaped ram, i think his was rated at 2.1 or something, and that gave odd booting problems too.
i got an asus board with nvidia 8200 now. uptime has been 17 days. it works.
