Thanks for the info. Next question: I haven't taken a look at my CSPPC in a while but it was crowded in there. Would the two sided modules fit? Also it says the memory should be 60-70ns. Would the 50ns ones work? I think they should but does anybody have a different experience? Also those SIMM's should be installed in pairs but for 128MB do they have to be all identical, ie. from one manufacturer, one model?
