I have 12GB ram Corsair XMS3 in my system on a Gigabyte X58 UD3R v2.0 and Windows sees all the ram but I don't seem to get any physical ram usage over about 6-7GB. I have noticed this since I built the PC years ago with most games I play that it seems to cap out. I thought it was just games in general with how they used ram but it definitely appears something with my PC. I was playing Anno 2205 and noticed this issue, I made the virtual memory swap file larger which made playing better but then noticed this in Task Manager while playing. Can someone enlighten me on what could be going on and how I can sort it out? From what I know the ram is good. Do I need to change settings in the bios or is the mobo just not good?.
