I have a brand new build and ran into an issue with memory. I put a ticket in with support but no answer yet. I have Gskill Ram DDR3-2133 16G. When I bought it I actually went to the Gskill Sight and got the compatible memory list and then bought it. All is well with two 4G sticks in the first 2 slots. Anything in the 2nd set of slots the system will not start. I know it is not the memory. I actually swapped out all the sticks in the first 2 slots in every conceivable combination and it always starts fine and indicates 8g running. This morning I even upgraded to the new bios (F15) and that did not change things. Thanks in advance if anyone has a clue other than RMA
