Can I use high density memory?

by on September 11, 2011

Q: Can I use high density memory? Is seems to be the most common available but some websites suggest it is a cheap alternative with compatibility issues.

I have a Compaq desktop with an athlon amd64. There are four memory slots and only one is being used (512 just now). I’d like to add another 1gig.

    I’m not sure what you mean by “high density memory”. Do you mean a stick of memory that has more than 512Megs on it?

    If you can provide the exact model number for the Compaq desktop I can show memory that is compatible with your computer.


    Thanks Mark, I did a scan online and got to this- ‘DDR 3200 DDR (non ecc)’. I just put that straight into eBay (try it) and there’s a vast selection, some pushing the ‘High Density’ aspect. Not wanting to get stung I did a bit of research and it seems to relate to the number of chips on each side of the module, but after that I got lost.

    The ebay posts about “high density” is basically just a marketing term you can ignore.

    Assuming that the scan you did on-line was accurate (you also try this one if you have’t already ) this kit should work great for you
    I would suggest removing your existing stick of memory and putting these two new ones in.
