Hi, I currently use on my motherboard 2 x 4GB CORSAIR Vengeance 1600 MHz but I can buy cheap 2 x 4GB CORSAIR Vengeance 1866 MHz. So I was wondering if they were compatible in order to use all 4 of them. Forgive me for my bad English.

A big Maybe, if they will work together, there's no way of knowing how or at what freq without knowing the mobo and CPU....most mobos out there default DRAM to 1066 or 1333, so if you mix the sets and they run it will prob be at one or the other. To run 1600 or try 1866 will require manual setup. Any time you mix sets, even the same exact model, it can be and often is problematic

as long as the motherboard and cpu supports the fsb it will work however mixing fsb will slow down the faster rams to the speed of the slower in this case the 1866 will be moving at 1600 so it will be as if you have in 16gb of 1600mhz ram

The 1866 RAM is only going to run as fast as your slowest stick, which is 1600MHz. Technically, you can run into issues when combining RAM like that, but for the most part it's ok to do. The fact that it's the same manufacturer helps, so I'd say yes.
