its an intel chipset. i dont have it in front of me, its an old office computer, used for like data entry and stuff. the micron works fine, because im using it right now in my cel2 633->950 1.85v cas2. when i get a chance to look at it, maybe i can get more info from it. the computer's about 3 years old, not like any other mobo, there's only one DIMM slot (that has 32 megs) and there's a SIMM slot taht i cant take out, it seems permanently stuck(that has 16megs) so it shows up 48 megs in windows
