It would need to be tested, but I’ve got 2 gigs of corsair XMS from my old machine that I’m pretty sure are PC3200. Power supply crapped out when it was plugged in during hurricane irene. I’ve been meaning to bring that machine back to life to use as a media center or to have to play games while my good machine is at school, but I’ve got one semester of school left, and I really have no idea what I’d do with it when I get an apartment.
It was a dinosaur, but it ran portal 2 and fallout 3 on medium settings.
