The cpu switch on the motherboard is on 1, im guessing that is the overclock setting.
Ok just to check, these are the steps i will take after the dog walk
Take out the cmos battery.
remove all ram, then try each one in slot 1 and enable xmp. then reset and try the next stick. Correct?
Not too sure if this is also related, but on corsair link it says gigabyte motherboard temp sensor 2 is -55c??
