First off, as it's probably obvious by this being my first post on these forums, I'm pretty much an advanced Hardware newb.. I know how to do all the basic stuff, but when it comes to tweaking my BIOS, stuff like that, I'm in the dark.. I've always used 1gb of Ram. One stick of 512 Mb CorsairXMS DDR3200 400MHz, and one stick of 512 Mb Corsair ValueSelect DDR3200 400MHz (*cringe* at ValueSelect). They've worked fine together, and I planned to upgrade the ValueSelect at some point, but wasn't too worried about it. I decided it was time to upgrade, and ordered a stick of 1Gb CorsairXMS DDR3200 400MHz Ram.. Popped it in, and alas, it still only registered as 1Gb total. I tried each stick individually, in each slot on my motherboard (3 slots total), and they all worked fine, so I know all 3 slots are ok, and all 3 peices of RAM are ok.. When I try different combinations of RAM, the highest I can ever get it to show, was 1Gb.. My boot screen and Windows both recognize only 1Gb of Ram, but some software, realized that it is being recognized, but just not being used. Screenshot from the Software: I've been poking thru the Bios a bit (It's a DFI LanParty UT nF3 250Gb), but can't find what I'm looking for. I see settings like TCL, TRCD, and just kinda bite my lip and cry a little. Any help would be greatly appreciated.
