Does anyone have any good result with the AMD X2?

I am getting a BSOD white loading ew.sys

Gigabyte K8NF-9, X2, 2 x 512MB Ram XP Pro (fresh install), fresh copie of GS3.1, no tweaks or whatever.

€: the same problem in xp home with gs3.04...

besides gs3 the system is rocksolig, no crashes so far.
