Hi there, i have a 8GB RAM kit (2x 4 GB) installed in 2/4 slots in Dual Channel. The RAMs are currently running on XMP with timings of 9-9-9-27 at 1.65v at 1600Mhz.
My RAM configuration : View: https://imgur.com/a/yRiqSuC



These are the rams: Model : KHX1600C9D3X1K2/8GX

Link 2 : http://www.ec.kingston.com/ecom/con...root=&LinkBack=&ktcpartno=KHX1600C9D3X1K2/8GX
(Both the same RAM, just different links for more information)

And i plan to expand my memory to 16GB by adding another kit of 8GB (2x4GB), filling all 4 slots. Unfortunately i couldn't find the same exact kit as above. So i'm looking at this kit below. My question is will it work in harmony at 1600Mhz?

The RAM kit i planned to add: Model : KHX1866C9D3K2/8GX

No one will be able to answer this.

Unfortunately RAM is only guaranteed in the form sold (from the same pack) as the manufacturing process and materials (silicon/solder paste etc.) changes frequently, and even dust particles in the air can influence the nature of the module.

Making sure they are the same make / model / timings is just a way to try and minimise risk, not eliminate it, and ultimately 2 of the exact same model from 2 different packs could technically completely misbehave with one another. It becomes a little more difficult when you are running a different number of mixed modules too.

Realistically, if you are going to mix modules, just try and make the timings, voltages, speed etc. the same, but in reality, even choosing the exact same model would yield the same risk.

It's for this reason that it's always best practice to buy a whole new pack of RAM. Not saying it never works, but it's a 50/50 gamble. So it might work, it might not. Only way to know is to try it.
