Ok, I flashed to the newest beta BIOS... haven't noticed any problems or improvements for that matter. Several settings go back to default, like CPU speed, N/B strap, memory ratios, RAM timings, GAT settings, and on-board stuff. But, the vdimm stays to what it was before the flash, so I was able to boot with my Mushkin RAM since I had already set the vdimm to 2.6v.
