I have 2 sticks of 2GB of Kingston HyperX Fury DDR3 1333MHz and 2 sticks of 4GB Kingston HyperX Fury DDR3 1866MHz. I know that the 4GB are C10, just bought them recently, but my old 2GB ones I have no idea, it was already few years ago.
My mobo works with dual channeling.
So, can and should I mix my new 1866MHz ones with the 1333MHz to get 12GB, or just use the new ones and have 8GB?

Simple answer, no don't mix and match ram sticks. It's always advised to run multiple rams out of a kit as opposed to buying multiple sticks to form your own pseudo kit.

Keep the system on the newly bought 1866MHz ram sticks and sell off the older sticks of ram or keep them to hand them down or have it as a spare part should you need it for troubleshooting.

Mind if I ask of your full system's specs?

Since you have them you can try mixing, not going to hurt anything, I'd try manually at 1333 would need the model # of the old to guesstimate good timings, can just try at auto initially. May need a voltage increase to the DRAM, if so prob start at + 0.05
