Could you attach your dmesg output from a clean boot. Specifically we
are interested in the e820 section of that output which shows how the
hardware/BIOS has layed out the memory in your systems.
Here is an example from a 4GB machine which is showing 4GB of ram within
the OS too:
$ head -1 /proc/meminfo
MemTotal: 4013952 kB

Note that although I have 4GB of ram, the last GB is actually mapped at
4-5GB physical.
