This is a bit OT, but you *must* run at least one full loop of memtest=20 in order to have significant output. I've had PCs that only broke on=20 test 7, and sometimes even a PC could run 2-3 loops before a bad bit was=20 found on the 4th loop or so. Only if there's a nasty error, like a=20 physically broken mainboard, you'll gets errors quickly. Despite that, I think your problem is not memory based, as you said you=20 use ECC, and I'd believe you've turned on background scrubbing. =2D-=20 mit freundlichen Gr=FCssen, Michael Monnerie, Ing.
