Motherboard: Gigabyte P55M-UD4
Processor: i7-860
RAM: 4GB F3-16000CL9D-4GBTD
Graphics: XFX ATI Radeon HD4870
PS: Rosewill RG630-2
Okay so here's the problem. When I have the ram in slots 1 and 3 (Dual Channel configuration) the bios sees both sticks of RAM in their correct slots, but it only lets me use one of them, in other words half the total RAM. Inside the bios, on the M.I.T. Current Status page, in the "DIMM Slot (MB)"row, it lists 2048 in both slots 1 and 3. In the "Enabled Slot (MB)" row, it lists 2048 under slot 2 only (and there is NO RAM in slot 2). In that same row for slots 1 and 3 it has "-". The under "Total Memory Size (MB)" it says 2048.
If I put either stick in slot 1 or 3 alone, it sees the stick and allows me to use its full capacity. If I put both sticks in the same channel, it sees both sticks and allows me to use the full 4 GB of capacity. So both sticks work, it just won't let me use both of them in dual channel. I have tried running the RAM way underclocked (1333) and up to rated speed, with different timings, and even voltages. All configs that will actually POST, it only lets me use half the RAM.
I had read other people having this problem with RAM that wasn't on Gigabyte's QVL for this board, so I made sure I purchased RAM that was on the QVL. Additionally, for many people who couldn't get another brand of RAM to work, they were able to specifically get the G.Skill Trident Series to work.
Any ideas on this problem? Should I just get a new set and hope that works? Hope there is a BIOS update to address this issue? I've also posted this to the Gigabyte to see what they say. Still awaiting response there.
Thanks,
Nathan
