I have 8gb of ram, and windows is only showin 7.8 of it. I tried going into msconfig to see if it the max ram was on but its not. im not sure why windows is saying i can only use 7.8 out of 8gb. yesterday i installed two new hdd and after that windows said something about the paging file so i have like 8gb of paging file. so im pretty sure its not that either
