Normally, with an FX CPU you can run the RAM at 2133mhz on a CHV (thats PC3-17000) so the ram you are talking about should run fine.
But, I beleive that most RAM's are the same in the way there "stock" speed is lower than their intended speed (in my case, I'm running G-Skill 2133mhz RAM, stock speed is 1600 and you need to OC the RAM to run it faster)
