This is a bit OT, but you *must* run at least one full loop of memtest in order to have significant output. I've had PCs that only broke on test 7, and sometimes even a PC could run 2-3 loops before a bad bit was found on the 4th loop or so. Only if there's a nasty error, like a physically broken mainboard, you'll gets errors quickly. Despite that, I think your problem is not memory based, as you said you use ECC, and I'd believe you've turned on background scrubbing. -- mit freundlichen Grüssen, Michael Monnerie, Ing.
