It might be a stupid question but I looked up gddr2 graphics card chips and I haven't found any results for the chips but gddr5 graphics card chips I can find. So is the memory chips on ram the same as the memory chips used on a graphics card? I want to know this because I got some cheap graphics cards that have ddr2 memory and want to see if I can upgrade them as an experiment even if people say you can't just upgrade the ram I want to try it for myself on these $5 max graphics cards I have to try to re-purpose them.
