I have windows 7, 64bit with 6, 2gb memory sticks (=12 GB)
control panel-system reports 8 GB (3 GB usable), while CPUID and other programs report true 12 GB.
When I had 6 GB true memory, control panel reported: 4 GB (3 GB usable). So in either case, control panel reports 3 GB usable despite actual physical memory.
Any idea of the discrepancy? Am I allocating memory to something else, so control panel can'see or use entire memory?
