I got this reply from Gigabyte.
Seems system has memory problem, please test with single stick memory a time, and check if mother board bios has option allow adjust memory voltage match to current memory spec.Test grapihc card in other system to confirm bad video card or unstable graphic slot on mother board. Also check if graphic slot on mother board is compatible with R465D2-1GI high memory card.
memory is fine and voltage settings match. Can someone tell me about the last part about a motherboard being compatible with high memory card?
I know this is an old post but this is still useful information for those trying to stretch out the life of an aging AGP video card interface. I had to go to the Gigabyte website and download a BIOS update for the video card. I could only get basic drivers to register until the the vid card BIOS update was done. This is NOT a motherboard BIOS update.
Dell GX270, Intel motherboard, Pentium 4 3.4mhz 800mhz FSB, 4gb DDR 3200 dual channel, 500gb SATA HDD and this Gigabyte 1gb DDR2 AGP card and the current hotfix 12.6 drivers downloaded from the ATI (AMD) website
