I have Win 7 with 64-bit and the PC will only use 3.25GB out of 5GB, and I need all my RAM for I play games. I have cleared my whole BIOS/CMOS, I cannot find a memory remapping function; and I am at a point where reinstalling the OS is not an option. I have also done "MSCONFIG" and that failed too, my motherboard, an ECS 945GCT-NM, should support 8GB of DDR2.
So, can anyone help me?
OK SO although it's kind of late because i've just noticed this thread ( had the same problem)
