@Ste, since socket AM2, AMD has started DDR2 support, anyway, ssjgoku24, I think highest Asus can support is DDR2-800, and not higher than that, though still look around for BIOS updates. though as I think only patriot is the manufacturer to relese DDR2-1000, I am not sure about the QVLA list of patriots in Asus's listings. though they support Kingston heavinly.
