ok. I am running.... Intel p4 Prescott 630 3.0ghz 800fsb ASUS P5GV-MX board 4x1GB stick Corsair Ram Windows XP Pro 64 edition ok heres the deal. I have everything installed included X64 os. I have flashed the bios with updated files from the asus website. When i go into the bios it says my Memory Size is 2934MB. When i go to system on the control panel it says 2.86GB Ram. But i have 4 gig installed. How do i fix this? It seems to me that it is some sort of bios issue, but im not sure. ANy ideas??? Oh i also contacted Asus tech support via the telephone and they said that all 4 gig is being used that it just isnt showing it. Is this true???
