2133 for 32GB, with a FX 8120? I wouldn't try.
I haven't looked for the AMD specs, but CPU World says that the fastest supported memory is 1866, but I doubt it would support 32GB at that speed.http://www.cpu-world.com/CPUs/Bulldozer/AMD-FX-Series%20FX-8120.html
Now, I would use the manufacturers configurators for choosing RAMs
