i just built a new pc my mobo is asus sabertooth fx990 but when i try to boot for the first time the red led from the ddr3 memory is on . I tried the memok switch for a few times but it still not booting.Does anyone knew a solution ?
Re-set the RAM in the DIMMs to ensure they are properly seated. If that doesn't work, try using only one stick of RAM, then the other(s), individually.
Thank you for your help but i've already done that with no result , is it possible that the ram doesn't work both of them , it is 2x4GB Corsair Vengeance (CMZ8GX3M2A1600C9) mobo is Asus Sabertooth 990FX , CPU is AMD FX6100 Black Edition , GPU is Sapphire Radeon 6850.All of this is compatible with the mobo.
