Need Help Memory Keeps Failing

[Ed-B]

Hello All:
I need help! I have a p5b with 4 1 gig sticks of Crucial Ballistix 8500, all 4 sticks went bad with the Bios at auto setting. Crucial Tech told me that auto sometimes under volts the ram. So they replaced all 4 sticks and I set the voltage manually to 2.25 volts the closest to the spec 2.2 and in less than 1 week 2 sticks are bad again. Does anybody know what is causing this problem.
Thanks Ed
