Hello currently my laptop has 128mb "2x64" of pc100 SDRAM. I cant seem to find the info on google or dell anywhere for that matter in regards to my upgrade options. All i could find was when they were sold from dell 512mb was the max you could get for it. My main question is would pc133 work? And if anyone knows is there a way to add more ram to it if 512 is its limit? Thanks.
