Other than the price ?

I downloaded the Kingston specs

https://cdn.cnetcontent.com/07/e9/07...f10cf84f67.pdf

Which says:

Latency CL9-11
Voltage 1.35V, 1.5V

It does not help at all in knowing if I can add a stick or
two.

My current memory is KHX1866C10D3/4G
Number of banks 8
Nominal Voltage 1.50 Volts
(CPU-Z output)
TIA
