I have bought a Dell Vostro 1400 with Windows vista 32bit. I am doing some simulation on vmware. Thus, i have installed the vostro with 4GB of ram. However, it only detected 3.5GB. Could anybody tell me is this normall? How could i "redempt" all those 4GB ram. Thanks for advise !
32bit can address 4GB, but what that involves depends on the system, and how it's used, because it takes up some of that possible address space to account for various other parts of the system which eats into that address space for IRQs etc.
Vista SP1 does 'see' the full 4 GB but alot of that is still going to be eaten into. Here's a quicky explanation including SP1's new support at softpedia;
