Problem
I'm running Windows 7 x64 RTM on a Dell Latitude D520 w/ 4gb memory. The system control panel reports: System type: 64-bit Operating System Installed memory: 4.00 GB (3.24 usable) Why isn't all the memory usable? Since I'm running 64-bit, is this a dell limitation? Edit: It's given me more question…
