dual channel Different ram Capacity Information

[HERO CODIZAL]

So i planned on buying a secondary 1866 speed 8 gig ram but sadly my nearest store only sells a 4 gig 1866 speed ram
HYPER X FURY  by Kingston
The single ram i have right now is 1866 MHz with 8 gigs 
I plan to add another HYPER X FURY with the same speed but a smaller capacity of 4 gigabytes.
is it okay to add a ram with lower capacity but with same speed? or should i wait for the restocks to come next month?
Dont Bother asking me to buy a 2133 mhz or 2400 mhz ram i have the amd 7700k apu and my  neighbor's 2133 mhz sucks his computer is unstable.

Are you maxing out your current 8 gigs regularly? If not, I wouldn't bother adding any more.

So long as voltage, timings, and speed match you can toss it in without problems.

It shouldn't be a problem. In my experience, Hyper X Fury ram is really good. I originally had two 4g sticks of ADATA 1600 (which looked horrible, didn't match my color scheme), and when I got my first pair of Hyper X Fury 1866, I plugged them in and they automatically set themselves to 1600 and were, and have been, rock solid.

 

Different capacities don't matter as much as timings, voltages, and clock speeds. As @AlwaysFSX said.

SO UHM SIR? ARE YOU AWARE THAT I AM USING AN APU?
THIS is the first time i am using AN APU. I DONT KNOW MUCH EVEN THO I AM A COMPUTER ENGINEER.
so sir if i put on the secondary ram with the lower capacity id be able to get more FPS in my games? just like those with dual channel and same capacity rams?

Please give a a better answer i am thinking about waiting for the ones with the same capacity for now

Those are the requirements for dual channel memory to work. If you need to to be dual channel it needs to match.
