This system takes a max of 512mb with 2 slots and the problem you are having is with the chip density. You need to purchase PC133 16x8 chipset module, or go with a PC100 16x8 module. Yes those are a bit more expensive than the standard PC133 module. I would recommend you to visit a quality
ram supplier on the web to let them help you or use their website to pick up the correct
ram. Try
