I built a new system last week. When I installed the RAM 2x16GB one of the dims didn't work so I RMAd them and got a replacement set.
I got the new set on Monday and everything has been fine. Today however I got a memory management error and the pc wouldn't boot. I was getting q code 55 and cc so I removed the ram and tried each dim on their own and wasn't getting any joy from either but after a few cmos resets I got one stick to boot and have tested it and its fine and the other stick will not on its own. It appears that any dim in slot 4 is being damaged some how.
Does this sound like a board problem and should I try to RMA it or should I just put up with it, after all I wont ever use 32GB RAM so all I will really be missing is the dual channel bit?
