As per title:



3GHz Core 2 Duo E8400 CPU

As per title:



3GHz Core 2 Duo E8400 CPU with 4GB RAM, only 3.7GB are showing in the System stats on Win 7.


What could be the problem?


It's a used machine, ex-government. The E8400 CPU has Trusted Execution and Execute Disable Bit technologies. It may well have a TPM (Trusted Platform Module), l don't know.


Could these account for the shortfall between quoted RAM and visible RAM?


It's not a problem of bad RAM, and it's a 64-bit OS.

Integrated GPU? If yes that probably eats some RAM (256MB probably).
