Hi RAYK47!
First of all, my system:
AB9 (none PRO) BIOS ver. 15
E6600
2 x G.Skill 1024 MB DDR2-800
EVGA 7950 GT KO superclocked
Two weeks ago I tested the XFX GeForce 7950 GT 570M Extreme in my system and its functioning very well. So XFX cards and the AB9 wasn't a problem to me. I returned the card to my dealer because its getting too hot, I got more than 100 °C GPU temperature while in 3d mode. This passive cooling thing isn't my taste when the cards is getting so extremely hot, so I ordered the EVGA.
Today I got the EVGA, and guess what I'm experiencing? .... Exactly (!) the same probleme as you have with the XFX card
Sorry about my bad English, I didnt pay much attention to my english lessons long time ago
