One more ram kit

[Voland11]

Decided to add additional 8gb ram kit to my pc( exactly the same as the first one [Kingston HyperX Savage 8GB CL9 1866 MHz ]). Will be there any compatibility problems with XMP or system stability or it is better to buy 16gb ram kit?

If they are matched RAM there shouldn't be. The RAM usually has timing information on the side. You'll want to make sure the timings, voltages and speeds are the same and if possible the same manufacture.
