Mushkin Enhanced Essentials 4GB DDR3 Laptop RAM - 996643 - Upgrade Memory for Faster Performance in Gaming, Work & Multitasking

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).
