I need more RAM. How much can I add, and is there any particular brand I should purchase? I purched this computer used so I don't know the specs.

According to the number you quoted this isn't an Acer machine!

However, if everything inside it is original, then you should be able to fit a maximum of 4Gb RAM.  According to the blurb, it has two memory slots  -  you will need to see how much is currently installed in order to know what to buy.

Here is a link to the Crucial memory website:-

I would add that  am neither an agent for Acer nor Crucial.  And indeed you can obtain suitable RAM from any number of other places...

   Please excuse my ignorance, but I have no idea which one I should buy. Should I open my computer and see which one matches my RAM, or is either of these compatable? Does the RAM I have installed have the information on it? Thanks for helping!

Hello,

P/N: PT.NB602.021

Model: eMachines ET1831-05

OS: Windows 7 Home Premium 64 bits

You already have 3 Gb memory (2+1) installed. You'll only need to buy a memory stick of 2Gb.

You'll find the memory information with HWINFO64 portable version (no installation).

You also have a PSU of 250W. A tool to determinate a PSU Enermax Power Supply Calcultor.

Thanks! theHWiNFO64 is superior to speccy. But will I have to upgrade my PSU if I make my unit 4GB's? And if so, how much?

No, you shouldn't need to upgrade your PSU.  The amount of current used by adding extra RAM will be negligible.

Hello sheriff12,

I'm in the wrong topic. Sorry. I confirm you don't need to change the PSU.
