I have a problem related about RAM and how Windows and the BIOS they use it. I have 4 Gb, and Windows and the BIOS just tells me that I have only 2 Gb (programs like CCleaner and others appears 4Gb, funny thing).
I have tried Memtest and the program tells me that there is not any error. BIOS tells me that RAM is running at 1333 Mhz, but programs like CPU-Z and HWinfo tells me 660 Mhz roughly. Here you have a pic about how the both modules of ram (#0 and #02) run using HWinfo and CPU-Z:
One question. Where I can find the option 'Memory remap' or 'Memory hole' On my BIOS? I don't see any option
