HP Recommended
Notebook 15-bw084ax
Microsoft Windows 10 (64-bit)

As per my research this laptop supports dual channel DDR4 1866Mhz.

But has a single 4GB module when bought. 

I want to make use of the dual channel and also add another 4GB for my needs.
But i cannot find any memory on the market with the same specs. will 2133Mhz work and make use of the dual channel support?
