The RAM module from Kingston is well made. It is in this Ram to a 2GB DDR 3 SODIMM memory, which operates at a clock rate of 1066 MHz. I use this product for my Acer Aspire 1551. The installation is done quickly (after all, is indeed a quick release, not the entire unit to break down, as in some other models, where it is first necessary). Windows 7 (because I have total increased to 4GB (2GB + 2GB old new) you need a 64 bit version!) Has recognized the module automatically and immediately integrated into the labor history.
