Hello!

I have a Gigabyte p55a-ud3 motherboard, and i want to buy a 1x8GB stick in it. Even though it has 4 dimm slots, 2 of them not working. and i found a good deal on a 8gb stick.
The maximum memory support of the board is 16gig, and it separates to 4 dimm slots. So one dimm slot can only use 4 gig ram? Or it can handle 8 gig ram?
Any experienses? Thanks in advance!
