Just looked up the motherbaord and the site i found says it supports DDR266 / DDR200 and Supports PC133 / PC100 speed ram
I'll tell you what, this is a site that will tell you exactly what ram will work on your pc.
It goes through the specs and gives the result. It is then as simple as finding that ram and gives you many options too.
There you go, and this will definetly find one that will work for you
Hope this helps
