ga-ma790gp-ud4h wont run at 1066

[dukeman]

i have this mother board and a X6 1090t running at 3600 stable with a changed multiplyer. 

now i have tried a Ocz memory and a g skill that both run at 1066 as per spec.  i get lockup and reboots if i set my memory to run at 1066 in bios with 2.0v.  if i run at 800 everything is great.  have bios F7c.

any idieals

Hi there,

do you have the same problem if you aren't overclocking the CPU?

[dukeman]

yes.  tried stock on the cpu with the same result.  after trying 2 different manufactures of memory i am beginning to think it is the board.

It could also be a problem with the CPU as it has the integral memory controller. Have you ever run your memory at an overclocked speed of more than 1333 ?
