@tom43ctwo , welcome to the Community.

What is the exact model of your computer?  I need this information to verify the specifications.

HP All-in-One 27-cb0244 Bundle All-in-One PC (318G7AA) I keep seeing that it shows two different rams in each slot DDR$ ram memory but not the same ram amount.

Thank you for the additional information, @tom43ctwo!

Here are the "Product" and "Motherboard" specifications for your computer.  If you look at the section in the motherboard specifications titled "Memory upgrade information" you will find the correct information on the memory.  This is the information that I have to use to answer your question.  The motherboard supports "Dual channel memory architecture".  Therefore, new memory should be installed in matching pairs to get the best performance.

I suggest that you open the case to see what is actually installed.  Some AIO's can't be upgraded even though there is information to the contrary.
