Summary: I bought this to upgrade an older Mac, and it worked rather well--but I will honestly caution buyers on one thing (which is why I removed a star): make sure you are really buying DDR and not DDR2 memory.
Summary: My old purchases are popping up for reviews. This was one of my 1st purchases on amazon(Wed, June 9, 2o1o). I found this item, at the time, significantly less than buying at it Best Buy or CompUSA. It came, it worked, no hassles!
Summary: Don't really know what to say about this. I got it, installed it, and it worked. Runs fine, and you gotta buy what the computer says that you need for it. The seller delivered it fast, sent a quality product, and him I can recomend highly.

Summary: i doubled the ram in a ten year old toshiba laptop in less than 5 minutes. if you wish to do the same, just double check compatibility, which may mean consulting updated material and specs not found in your old user's manual.
Summary: The ram stick was exactly as described. It revived an old system that now run twice as fast. It made a noticeable difference in the speed of my Windows XP machine (3.0GHz, 2X512MB DDR, 533MHz, IDE HDD).
