basically in my system right now i have 2x512mb corsair pc4400 ddr ram, although its only running at pc3200 i cant really be bothered to overclock it all and fart about but i was wondering if i could chuck in another two 512mb sticks of pc3200 basically i got another gig of twinmoss ram sitting around and i really think my system would benefit with another gig, is it possible to run both sets so i'd have 4x512mb in my comp as long as obviously the timings were set to run at the twinmoss (slower) settings.
