My system consists of the following Asus X58 mobo i7 950 6gb Corsair CMX6GX3M2A1600C9 RAM OCZ Vortex SSD Problem is motherboard only recognises 4gb ram. Board went back to Scan seems there is a prob with these boards, eventually came back as they said there was a fault with the board. They replaced it so rebuilt it all and lo and behold SAME problem. Now they are saying send board. modo and processor back! Dont really want to do this - last time took long enough. Anybody else had this problem or any ideas?
