Im running A7M266 with PNY Geforce3,40g 7200rpm drive,pioneer dvdrom,cdrw,Soundblaster Live, 256DDR 2400 Corsair Brand Mem. System runs great be sure to check all jumpers on board I got a retail box board and still found jumpers in wrong settings. Also make sure you load latest AMD Miniport driver and then get via 4 in 1 with the agp driver checked off and you should be off to the races.Remeber with A7M266 you are purchasing a board with Amd North and Via south bridge.Thats why its important to have both sets of drivers.
