Mushkin Enhanced Essentials 4 GB Laptop Memory 996643

Got these to upgrade the 2 Acer Aspire One Netbooks (D255)s that my sister and I purchased when they were on a good sale. Perfect match for them. unfortunately you can only upgrade them to 2GB max and you have 1 RAM slot in which to do so. For the performance, price, reliability, and lifetime warranty, Can't beat it. Mushkin makes great products. Amazon has great prices and free shipping, when their powers combine.... hah well it's a good deal!The RAM installed w/o a problem, booted up first time w/o any issues on both netbooks. The performance is VASTLY improved on both of them. I totally recommend spending just a 'lil bit of money to upgrade your netbook if you have one(and if you can).

Installed in a 13" MacBook Pro with no problems. Memory worked right away. Big performance increase on the computer when multiple apps are open.

What can I say, this kit is affordable and works great in my wife's MacBook. She had 2GB of RAM and is always multi-tasking and her machine was dragging a bit. So, we popped these in as a replacement and her machine is much snappier now. Good buy...

I have been using it for a few months now (maybe years) and no problems at all. Upgraded the RAM on my HP DV 6500t - The laptop specs say that the max supported memory is 2 GB but that's not true. HP probably wanted to avoid confusing the users when 64 bit OS was not that famous back in 2009. Now that Win 7 x64 is so common, its easy to use all that 4 GB RAM.

Had these running for some time now, gave the computer a good boost of speed and have not had any checksum errors or failures. Very good for the money.
