It could be a different problem (Windows may calculate RAM differently in
different places, where did you check it?).
I'd start with a memory map (see Sven Hartge's comment in this thread),
also see https://en.wikipedia.org/wiki/E820
A similar tool for Windows is "Rammap".

With 32bit system you would never be able to use 4GB (because part of
address space is used for MMIO by PCI-(express) devices).
With 64bit address space is much larger, but some ram is used by kernel.
Some tools exclude such ram.
