There are websites where you can input the manufacturer and model of your computer OR motherboard (in case you built it yourself), and it will tell you which RAM modules it can take.  It if lines up with the specs of this memory module, you're good.  It's best to have matching pairs of RAM modules, so if you're upgrading from 4GB perhaps you should get a 2-pack of 4GB modules for a total of 8GB.  (You can buy them individually or as a 2-pack)  ...  Make sure you don't go over what the website says the total capacity your computer can take is.  Good luck.  :)

Question 2

is this compatible with Dell OptiPlex 790 Small Form Factor?

Accepted Answer

Yes. However, the spec sheet states that the 790 ships with RAM only clocked at 1333 MHz. If you mix existing RAM with this it might under clock to match, but you might run into stability issues. I would look at this as a replacement, not an addition.
