How do I know how much and what kind of RAM to get for my computer?

by on August 17, 2009

Q: I want to upgrade my old PC by adding more RAM (256 or 521). The problem is that I’m new at hardware and stuff. I know there are many types of RAMs DDR, DDR2 and what not so which type should I buy?

Also I currently have single chip with 512MB. If I insert lets say 256 next to it will it work, or does it has to be 512MB like the first one?

This is my system report.

    Thanks for sending the system report!

    Here is the spec page for your motherboard as reported in your system report: http://www.asrock.com/mb/overview.asp?Model=K8Upgrade-NF3&s=Archives

    As you can see on that page it says:
    – 2 x DDR DIMM slots
    – Supports DDR400/333/266 non-ECC, un-buffered memory

    So we now know that you need DDR RAM, and that 400, 333 or 266 will work.

    A 256meg stick should work, but the prices on the older DDR RAM are very low. You can buy a new stick of 512meg for only $10-$20 US.

    All of these should work fine for you: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010170147%201052307857%201052107965&name=184-Pin%20DDR%20SDRAM
