A7V BIOS 1008 final unstable

I flashed with the latest braziliantech mod bios (enables temp fix), from the stable 1007/fxd. But, unlike the earlier version, it became very unstable, giving me freezes in 3DMark 2001 and 3D games (man, Max Paynes roxor!). Flashed back to 1007/fxd, and everything worked flawless again. Someone else using it? Or using the oficial Asus bios and getting this kind of problem?
Well, I didn't tryied reinstall my det drivers, flashing the original bios, or even my winxp rc1 2509 (kicking tush with it!)

i m using the a7v 1008 beta bios.....it works fine.......i have been using it for almost 3 months now

Hmmm... wadda memmory settings do u use?
Could u give me a snip of your bios settings?
