Memory

[Christer Wickman]

Hello Everybody. 

I have a question about memory. I have changed my memory in my computer recently. Before I had 2Gb memory, but now I have 4Gb. Should one change from a 32-bits to 64-bits? I'm using a 32-bits Ubuntu just now. I have tested the memories I have and both of them works as the should. But when I them both in the computer it says that I have is 4035 Mb memory. So it is missing 61 Mb, so I hope you all can give me tips on why I am missing 61Mb. There is nothing wrong with the memory. A friend of me told to install the 64-bits version instead of the version I have now. Would it be better to install the 64-bits version? Please I would be very happy if you can help me. I use XUbuntu v. 14.04 LTS 32-bits version. 

Yours
