You should have looked over the other post, this question has been answered about 1000 times in here. PC133 is balckwards compatable with PC100 and PC66. If you have any type of SDRAM you can use PC133 in your system, which is available for around $20 for 128MB these days at the online discount stores. 133 is simply the MAXIMUM speed that the memory is garrunteed to run at, not the minimum. You can run it as slow as you want. The only chipset that needed an older style SDRAM is the Intel VX, which is not a PII chipset.
