Both in window properties and task manager, system is displaying 2.73gb, although i have 4gb installed. Bios shows all memory working in dual channel mode, and CPUZ displays all 4 sticks present. I had this problem when i was on 32bit.
The OS is a clean install, not upgrade.
Version is Ultimate 64bit , SP1.
Using andAMD 4400+ @ stock 2.20GHz.
Any ideas what's wrong ??
