i have windows 7 home premium 64x with 16GB of ram installed. i have tried switching their slots, blowing out the slots, cleared the cmos, when i run resource monitor it shows hardware reserved memory is 8gb, but i dont know what can be reserving that much memory. bios only shows 8gb of physical memory as well, also shows 8gb of L3 cache in bios? system specs are 760gm-p34 mobo which supports 16gb, fx-6300, gtx660, 16gb crucial ballistix sport. the ram sticks are identical. so the question is why am i not able to use all my memory
