I have an existing 256mb RAM and with it i installed an 512MB RAM
but now i cannot boot my system successfully..!!The bios showed 768MB of ram but on further going windows showed a bluescreen and restarted.After that when i restarted eventhough BIOS showed 768 windows showed an exception kind of thing.I again restarted and windows logged in and to my astonishment only showed 512MB of RAM...!!!I have used that 256 for nearly a year and it is defect free. Both RAM's can run individually but on strapping both together only 512 will be shown..!! I Have got a ---
AMD ATHLON 2600+XP
both of my RAM's are 400 MHZ nut my POST shows only 333Mhz my board is sure for 400Mhz support..
