Ram upgrade compatibility

I am looking to upgrade my Acer Aspire One 532h 10.1 from 1gb ram to 2gb ram. Should any old 2gb ram card off of ebay do or do I need a specific type (ie is netbook ram different). Sorry for the noob question, just this is my first netbook. I got it about 6 months ago, and it works great. I am able to get Spore and Oblivion to run fantastically on it, but NBA 2k11 and James Bond Blood Stone are a touch slow even when I overclocked the cpu. The last two claim they need 2gb to run on windows 7, yet they manage. I assume it is because win7 starter is less of a resource hog than win7 home, but I really want to see what I can get out of this machine with the 2gb upgrade given the 64bit core. Thanks in advance for any help.
