anyone have any luck with 4x1gb of ram with this board, can seem to get memtest to not get errors with 4 sticks.........im using one kit of g.skill hz d9gmh and one kit of ballistix 6400 d9gmh......any help would be appreciated, thanks.......and do i need to pump alot of voltage to the mch to handle 4gbs?

could it be the F4 bios, should i go back to F3????
