Answer» I have G41M-VS3 R2.0 Motherboard and I CURRENTLY have 2.0 GB dual channel Ram of memory installed and it works fine I just bought another 4gb of dual chanel memory that is 1333mhz as well but when I install it my computer just doesn´t start with it when I have it on. I looked at the requirements and to me it seems that it should work but it isn´t. Here is the specs for the computer and RAM that I used, Please help if you would if I missed something. THANK You, it is much appreciated. http://www.asrock.com/mb/Intel/G41M-VS3/ You will have to return the memory to the vendor. Meanwhile, you need to check and make sure you know what works in yout motherboard. http://crucial.com can tell you what your PC has and what you need to upgrade it. The site will install a program to probe your PC. It is not spyware, so LET it install. You can remove it later. Thank you very much i´m GOING to go back and buy some new memory tommorow . Thanks a bunch (:You're welcome.
