Biostar site says "Support Dual Channel DDR2 533/667/800/1066(1066 by AM2+ CPU) MHz" so yes the RAM will be fine. It doers not say it supports Phenom x 6 processors though. see http://www.biostar.com.tw/app/en/t-series/content.php?S_ID=432
In the cpu support tab,it says phenom x6 supported both 95w and 125 w versions.
But in the compatibility list there is no transcend 800 Mhz DDR2 ram support.Will it be ok to put that 2 gb ram stick in this mobo?i will use it for gaming (with my old radeon 4870) and some college stuff.
