What does the last letter of frequency means 12800s?

what is different between 12800s and 12800r

Are those memories compatible?
 
Solution
The "R" means it is registered memory and is usually only used in servers or maybe in some workstations.

The "S" means it is SODIMM memory which is normally used only in laptops and notebooks.

The two memory types can't be used together at the same time, they are not compatible with each other.
