How to fix: Only 3.25 GB Usable of 8GB Installed RAM.
Recently I have upgraded the memory from 4GB to 8GB on a system with the AsRock 4Core1600Twins-P35 mainboard. After installing Windows 7 (64-bit) and while looking at the System Properties, I realized that the system while properly recognizes the installed memory of 8 GB, says that only the 3,25 GB are usable.
