CMS 1GB (1X1GB) DDR2 5300 667MHZ Non ECC SODIMM Memory Ram Upgrade Compatible with Acer® Aspire One Zg5 Netbook Ddr2 Sodimm - A58

Fits perfectly in my Acer Aspire One 255W notebook. So far it seems to be working perfectly.

It worked great, except that I did not know that one of the sticks of memory (512mb) was built into the mother board and I could only replace one. It would be nice if that would have been noted on the advertisement so that I would have only bought one instead of two. Installing the one though did help out but not as much as I expected. I put it in an ACER ASPIRE small laptop.

Breathed new life into the lagging netbook. Now running Windows 10 & only missing 2 or 3 beats instead of 15 minutes of beating! I guess next is an SSD to make the baby actually work like a real computer. Used the guide at [www dot ifixit dot com slash Guide slash Acer+Aspire+One+ZG5+RAM+Replacement slash 3781] and had no issues. I just don't know what to do with this extra screw!?!?!?

I give this a 4 star because I would have liked more memory, but this did help quite a bit. I upped the ACER ASPIRE ONE netbook from 1 gbyte to 1.5 and added a 32gbyte ssd to replace the existing 8gbyte ssd. Made the little netbook much more useful.

Made a big difference in my Acer Aspire One's performance. Easy to install once you figure out how to take the case apart. Here is a hint- keep track of where each screw came from. It will save you a lot of trouble putting your computer back together.

Worked as advertised. Great service as well.

Worked out great although I did have some 1GB sticks of DDR2 already, I didn't know if they'd have worked or not. Guess they would have but I'd rather be safe then sorry.

Sluggish performance was alleviated by adding more memory in my Acer Net-book.I am very happy with my purchase, you can't have enough memory with today's programs and apps.
