Hi all i got a GA-K8N-SLI board with AMD Athlon tm 64 3700+ cpu with 4GBram and Vista Ultimate X64 , my question is, is there a bios update to actually make my motherboard vista 64 compatiable as i have noticed if i install a display driver for my video card instead of reading 256ram for it , it reads over 2gb at the moment it reads 520 with just the driver window installs. Any ideas.
