Ram type

[Gonzo57]

Hello,

 I have an HP all in one computer with an HP84DE motherboard and I want to know exactly what kind of RAM do I need to upgrade from 4GB to 8GB. It is the Walmart special I also would like to upgrade my Vidio card to the best one this DIANSAUR of a system can handle. Thank you very much in advance.

Thank you, everyone! It was a lot of research and with your help, I was able to narrow down the RAM  type I needed. These all in ones are very hard to work on since there is only so much you can do with it. It is now operating at the level I needed for a Personal computer. Once again THANK YOU  to everyone that helped me.

In any case, thank you, but the best way to thank me would be to mark the solution.
