Hello,

I have an Asus PRO-H170 motherboard that supports 2133mhz memory.

I have an opportunity to buy either:

Kingston HX 16GB DDR4 2133MHz CL14 kit HyperX Fury Black

or

Kingston HX 16GB DDR4 2400MHz CL12 kit HyperX XMP Savage

What's the best variant for me? I need a rock-stable system.


Is it better to buy 2133 on CL14 or 2400mhz on CL12? How will 2400mhz perform on H170 chipset in terms of stability?

Thanks!
 
Solution
if the same price buy the faster one. The board will run it at what speed it can, I wouldn't be concerned. The XMP profiles will take care of it
