JohnnyAshes 0 Posted December 21, 2009 Hi all, I am new to this forum. I just bought a Samsung stick of 2GB 2Rx8 PC2 - 5300S - 555 - 12 - E3 ram. Why won't this work in my Acer Aspire 5520? I currently have 2x 1GB 2Rx16 PC2 - 5300S - 555 - 12 - E3 installed from factory. Shouldn't the lower number (i.e. 2Rx8) be more compatible? Thanks in advance. Share this post Link to post
danleff 0 Posted December 21, 2009 What is the exact product number of the Samsumg stick? Are you using just the Samsung stick or are you trying to use a combination of the old and new sticks? Oh, and what is the exact model of the Acer (eg: 5520-5908)? Share this post Link to post
DosFreak 2 Posted December 21, 2009 You bought 1 single 2gb stick to replace 2x1gb sticks? Bad idea. Share this post Link to post
JohnnyAshes 0 Posted December 22, 2009 I was trying to run the Samsung with one gig of the old stick. It's a Samsung M470T5663QZ3 - CE6 I believe the model is an aspire 5520 - ICW50 Share this post Link to post
danleff 0 Posted December 23, 2009 As DosFreak suggests, installing memory in exact make, model and type pairs is the best way to go. I am not sure where or how you bought the memory, but using the memory manufacturer's memory config. utility is the best way to go. According to the Crucial memory site,you don't have to install in pairs, but will get you the best dual channel configuration performance results. Does the new stick alone work? If so, you can buy another stick of the exact model number and you have increased your RAM. If not, you know that your machine does not like the new RAM at all. Motherboards can be picky about RAM. I saw nothing on the Acer site and their user manual and their support site is silent about what RAM to use or what has been tested to work. Of course, I may not have looked deep enough at their web site. Try posting on a forum where users may have experienced the same issue or that has a section dedicated to Acer laptops, such as this forum. Share this post Link to post
