I installed 8 gb of Corsair vengeance lpx ram (4x2) Into my ASUS H11OM-A motherboard and when I run msinfo32 it says only 4.12 of it is available. Please help, I have tried completely turning off my computer (Shut down, unplug power cable) and when I restart it and run msinfo32 it says maybe 5gb or over. Please help.
