I currently have 12gb of Corsair triple channel ram installed in a GA-X58A-UD3R but the bios only shows 8gb. When in Windows7 64-bit I show 12 installed but only 8gb available and from that I then lose the normal stuff for hardware reserved. Am I missing something here. I have moved the ram around and nothing changed. I had this issue when I first had only 6g installed but added 6 more and nothing seems to change. Any ideas?
