@Daddyhillbilly1 , welcome to the Community.
The main thing that you have to do is make certain the memory is compatible. Here is the Maintenance and Service Guide: http://h10032.www1.hp.com/ctg/Manual/c04331008
On Pages 100 thru 102 is all of the information that you need to know about the current memory in your computer. If the old memory doesn't match the specifications in this section it won't work.
