Are you on the latest BIOS for your motherboard? You might want to see if all 4 of the sticks have the same make and model, if they're all Corsair XMS sticks of ram.

all of them are xms3 all with the same part number also the same frequency in mhz all the same version and volts

also i had to update to the newest bios for it to run the i7 3770 as this was at a later bios update

sooo therefore i am at a loose end any 2 sticks of ram work in slot 1 and 2
