Interesting...What board revision, and what BIOS?
I have a Rev.2.0 F9b and just tried running memtest86+ v1.7 on some Crucial Ballistix PC2-6400 that previously passed with flying colors...this time they started popping up errors immediatly. I backed off my speeds/timings, but it did not help. They previously passed without error on F7 & F8...
Consequently, I just completed an RMA request last night for a G.SKILL 2x2GB PC2-8000 kit I just got from newegg last week because they were failing memtest the same way (even with relaxed speeds/timings).

Now I'm thinking maybe they're OK.
I think I may try flashing back to F8 and see if the problem remains.
