I recently just switched over to x64 rather than x86 to take full advantage of 8GB Ram. How can I tell easily that I know it is using it? (rather than Task Manager).
it'll use as much ram as it needs to, I have 16GB it only uses 2GB at idle, 8-10GB when running a VM and gaming. task manager will show you. page faults tell you how often you are hitting the swap flie, it should be lower than it used to be.
