Hey.
I've had this issue since last night. I have 2 sticks of 4 GB of DDR3 RAM, adding up to 8, in my motherboard. Before I installed Windows 8.1 64 Bit, the BIOS says that I have 4 GB. When I look in the BIOS, I checked the RAM settings, it says in slot 1 (DIMM 1) there is a 4 gb stick, and in slot 3 (DIMM 3) there is a 4gb stick. I also checked my system info in Windows when I installed it, and it says 8gb (3.9 usable). My brother finished building his pc not long ago, and he had no problem. I also noticed that his BIOS version is 1503, when mine is 0906 (UEFI BIOS). My mobo is ASUS M5A97 LE R2.0. This is also an RMAed motherboard, if that possibly has to do with anything. Any help?
