My ram is pc 100, and 64mb, i was going to upgrade to 128mb, if i was to buy 128mb on top of my existing 64mb, would this still work? Thanks for any replies.
PC100 ram has 168 pins, it does not need to be paired. Older memory, such as the 72 pin ram does need to be paired. If your computer has PC100, you should use PC100 or faster. So long as you have a free ram slot, the upgrade should work. Still, you should check your users manual just in case there is any kind of restrictions on memory combinations.
