Before Windows Vista SP1, all x32 (32-bit) computers didn’t display 4GB within the computer although 4GB is installed. The computers would allocate 256MB – 512MB RAM for video, motherboard, and resources. That would leave app. 3.5GB left for applications and processing, the real reason for installing so much RAM.
Now, Service Pack 1 for Windows Vista solves the 4GB jip. No more are you jipped when you upgrade to 4GB of RAM. Now, when you install 4GB of RAM, you get and are shown 4GB of RAM. This is the first big win for Vista – RAM is actually accurately allocated.
