This is exactly what I've been looking for..I have a Evga 770 GTX SC 2GB version, I'm decently versed in messing with the bios on Graphics cards, and laptops etc, and recovering from fails using my lil bus pirate and decent with soldering I was pondering, could such a thing be attempted with upgrading a 2GB card to a 4GB card using higher density ram chips of the same brand, I know that the 4gb version of my card doesn't use extra chips, it uses higher density chips on the same pads I also know the bios of the older ATI/AMD cards had the memory timing tables in the bios that you can select or alter, but from the looks of your post it appears to be selected in hardware via a resistor of a certain value for nvidia based cards, is that likely to be the case for the desktop editions of the cards aswell? if tldnr: is it a possiblity to upgrade the ram on a 2gb nvidia card when a 4gb is avalible for purchase? and is it likely the desktop cards have a similar resistor edit: why would I want to try this? cause tinkering moar power! and excuse to finally get a hot air station and some bga templates
