Adding Ram to Compaq Presario SR5120AN Desk top

This PC currently has only 512MB of Ram and on investigating how much Ram this PC would upgrade to, the specifications say it supports up to 4 GB* on 32 bit PCs. Then it goes on to refer to the asterix and says *32 bit PCs cannot address a full 4.0 GB of memory.

Does this mean it won't work with 4GB of ram or does it mean it can't use all 4GB ?

Yes, 200 to 300 MB won't be used.

The remark is just the same for ALL computers from all manufacturers running under any version of the 32-bit Windows OS. Due to the OS limitations those just can not use the full amount of RAM.

4 GB RAM works fine, but only 3,7 (app.) will be used by the OS.
