I agree with Bryan, I've rooted out quite a few bad memory chips with this app. There's also standalone bootable images at: http://www.memtest86.com/ Make sure you are able to verify at least some good memory in the motherboard before you blame the memory though. I've run across a few motherboards that tested good RAM as bad because they had problems elsewhere. -Russell Bryan Murphy wrote: > All bootable Gentoo Linux cds come standard with memtest86 as a boot option. > It's a darn fine memory tester. > > I suggest giving that a shot before trying a hardware based solution. > > Thanks. >
