Just a little warning about the a7a266 mobo. When attaching the HSF be very carefull! On the left side of the Socket the center notch that the HSF grabs on to there is a very small resistor place right next to it and if the clamp of the HSF catches that and disloges it your mobo will not post anymore. I found this out the hard way. after fighting with the board for 2 days testing every piece of my puter I finaly saw the resistor twisted out of place. So be very carefull!!!!!!
