actually i went to the amd website and installed optional drivers package. and it had way better updated drivers. seems like asus is done supporting this motherboard.
but what i did was downloaded from here http://sites.amd.com/us/game/downloads/pages/integrated_win7-64.aspx#2
chipset drivers and raid drivers.
but the raid drivers on a usb flash drive.
restarted to bios.
set sata ports to raid instead of ahci.
booted my windows 7 64bit ultimate disk.
loaded the raid drivers from my usb.
