20-c020 all-in-one memory questions

[Aack]

I bought my wife a new HP OPP All In One for christmas (20-c020) and it is running painfully slow.  I saw that it only has 4 GB of RAM, and the pamphlet it came with stated that because it is the AMD I can only upgrade to 8GB using 2 modules. So, I bought the recomended modules, and opened it up to install them. There is only one slot. 😕
Guess I'll be sending those back...

What memory type can this computer really take since the pamphlet is wrong, and can it hopefully use more than 8GB?

On a side note, if it is still slow with the max, since I bought it several months ago, is there an option to trade up to a newer/better HP? This is currently running slower than her 7yr old laptop I was trying to replace was, and I am hoping the memory is the issue.

Thanks in advance.
