Yeah pretty much teh same story with Garet Jax here. No matter which UDMA drivers I tried, and no matter what BIOS I used, the board wasn't very stable. And I tried a P3-600B (133FSB, Katmai core) in it, and I had incredible stability problems. Don't get this board. Better to spend the extra $20 or so to get a P3V4X (Look in the FS/FT forums... you'll find one).
