Im not sure of the exact brand, im buying a P3 550mhz of a mate, and im just checking if im going to be able to get by with ram. I know its not a great motherboard, but its better than what i have now...*cough* P1 110mhz...128 mg is all i need for this computer, that will get me by. If the Pc 133 doesnt work, what sizes of Pc 100 Ram are there besides 32?
