ok. I am running....\r\n\r\nIntel p4 Prescott 630 3.0ghz 800fsb\r\nASUS P5GV-MX board\r\n4x1GB stick Corsair Ram\r\nWindows XP Pro 64 edition\r\n\r\nok 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. \r\n\r\nHow do i fix this? It seems to me that it is some sort of bios issue, but im not sure. ANy ideas???\r\n\r\nOh 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???
