Dummie upgrading pre-built pc

[Hottea]

Hey guys,

 

I am not really PC savvy person, so please keep that in mind when you respond, thank you!

 

Nearing Black Friday I am considering upgrading my pre-built bought PC and I have RAM expansion question.

 

MB: Asus H110M-R, as far as I can tell, there are only two RAM slots available.

The PC came with a single UDIMM stick:  Cricial 8GB DDR4-2133 CT8G4DFD8213.C16FHP

 

I am having trouble finding any local vendors who would still sell DDR4-2133, therefore I am looking for options here.

 

Would love to at least double, to 16GB, but is it possible to simply install a faster RAM dimm and be done with it ?  

 

I'm grateful for any input,

biggest concern is voltage the stick you have in 1.2v.  are yu unable to buy online? if you can just look up CT8G4DFD8213. lots of places to buy.  make sure whatever you buy is 1.2v.
