Ok so I've got this problem where I have 8GBs of RAM installed physically in my PC but the System tab in Control Panel says I can only use 4.00GBs. I have checked my Mother boards booklet and it supports up to 32GBs of RAM so I should be covered. My windows 8 is 64 bit so that should be good. I've checked task manager and close all the backround processes but that doesnt help. The only solution Im left with is the BIOS Memory Remap Feature. I have a Gygabyte GA-78LMT-USB3 MotherBoard. Please help, If I don't have or support the Memory Remap feature.. what am I going to do?? 🙁
