Correct the .51gb has gone to the GPU. the 4th GB will not be used since you have a 32bit OS. You need to get a 64bit OS to use all of the 4 gigs of ram.

There's a difference between addressable memory and  usable memory as stated in the KB article, so what's your point?

You can't. Any operative system reserves memory for "internal use".

Did you check inside BIOS Setup? Maybe there's an option that allows you to change shared memory amount.

Well, I recommend you to migrate from 32 bits to 64 bits.
