just make sure that if you have 168 pin memory to use 168 pin memory.
if you have 184 pin, then...you guessed it, use 184 pin memory.
i believe, but please correct me if i'm wrong...you can not use pc-133 because it is a 168 pin and pc2100 is 184 pin.
look at your memory sticks. if they have 2 gaps on the bottom, they are 168 pin, if it only has 1 gap, they are 184 pins.
they will not work in your mobo.
