Need a little help.
Today I turned on my computer with the GA-P67A-UD4-B3 board and it would just restart over and over again, so I took out one stick of ram and it booted up but I can't get dual channel. I've had this board for a couple of weeks and it was running fine. Seem's that if you put a stick of ram in the fourth slot now it will not boot but just restarts over and over again. Computer boots if I have ram in slots 1 and 2 but that's single channel mode. I'm testing the two sticks of CORSAIR Vengeance 2x2GB 240-Pin DDR3 SDRAM 1600 but so far no errors.
Big question, did the fourth slot just up and die?
