Hi folks,

I'm trying to buy an additional 4GB of RAM for a friend's PC, the details on the existing stick are:

SK hynix
--------------
KOREA

1Rx8 PC3L - 12800S - 11 - 13 - B4

HMT451S6BFR8A - PB NO AC 1516

I've found a 4GB on amazon which is identical except instead of "PB NO AC" it says "PB NO AA". Would this be compatible with the exisiting stick?

Let me know if more info is needed, thanks for any and all help :)
