ive got an old p3 "dell optiplex gx1" running 2000 pro and has 64mb sdram ram my question is if i upgrade the ram to 256-512 will it run perfectly because atm its slow as crap
You've got 3 DIMM sockets, which according to dell will take a 128MB module max, 256MB if they are ECC. Maximum supported RAM is 768MB but that will be ECC. Non-ECC will cap at 384.
