Will these RAM sticks be compatible with my current setup?

Solution
For the smoothest operation, I'd suggest buying a new matching 16GB (2x8GB if your board supports it) kit rather than mixing & matching.

While the chances are slim that there would be any substantial issue, if there was to be an issue it's a real pain to try to rectify.

What are you using the setup for? Timings & speed have only a very minor impact on performance in the vast majority of tasks.

The increase to 16GB would be a nice boost - so much so, you could probably drop down from 1866MHz to 1600MHz and see no negative impacts in 'real world' use.

If you wanted to keep the 1866MHz speed, CL9 is available, and reasonably priced too...

There is always a slight risk when mixing & matching differing modules/kits of RAM.

Are they compatible? They should be - you may just need a slight voltage boost (like +0.05V max) to get them running together nicely*.

*Again though, there is a minor risk that they won't 'play nice' regardless.

What do you suggest I do? Sell my current RAM stick? If I do, should I just get a 1866 CL10?
 
Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards can be very sensitive to this.
That is why ram vendors will NOT support ram that is not bought in one kit.
It is safer to get what you need in one kit.

Ram is cheap enough.
I suggest you buy a compatible 2 x 4gb kit and keep the old ram as a spare.

How happy would you be if the new kit did not work?
What would you do then?

I was looking for the exact same RAM but Adata stopped producing them and now there not being sold anymore. Newegg is the only area that has it but is asking $100 XD. So should I buy 1866 or 2100? My Mobo says it supports 2100OC.

What is your motherboard and cpu?
Ram speed is generally irrelevant for Intel processors.
More so for amd.
1866 is about right for intel, go faster for amd.

ASRock Extreme 3 R2.0, with FX-8320. This is a budget build I have. I will be making a new build sometime in the future.
