Ive got a question about mining for you. So Today I built a 6 card rig with that same motherboard. Msi afterburner picks up all the cards but I can only change the fan speeds on the first 4 of them. Also when I go to mine it's only used the the first 4 cards to mine. Do I need to adjust something in the mobo bios to get the last 2 cards to work or something? Im using Windows 7 pro

Thanks
