64bitWin7 only sees 2.94/4GB of ram

Win7 Pro x64 says 2.94GB available out of 4. What gives, I'm using a 64bit OS??

Did you set memory remapping in BIOS?

In addition... Start | Type msconfig in the "Start Search" field, and hit ENTER | Configuration Utility--> "Boot" tab | "Advanced options" button | Under the "BOOT Advanced Options" dialog, make sure the "Maximum memory" option isn't checked. If it is checked, uncheck it and reboot.

Fixed it, thanks. I had use of all 4GB under Vista 64 so I just assumed it was a Win7 issue, since I didn't change anything in the bios. Somehow that got turned off during the clean install though...
