WHY DOES FX9590 MULTIPLIER CHANGE

I have built a ASUS Sabretooth FX990 r2.0 with a FX9590 CPU, and have upgraded all components to accomodate (1050W gold rated 8- plus PSU, Corsair H100i water cooling system, G.Skill ARES DDR3 1866)

But am encountering some odd performance issues. My CPU-Z ID readings show the primary core multiplier to be floating between 7 and 25, with a corresponding clock of between 1400-5000 MHz. Is this normal? I would expect to see a minimum of 4.7GHz as this is the given factory speed even with turbo core disabled. The previous CPU was a Phenom II X4 975 BE which delivered a solid 3.6GHz consistently.

 

One other thing, the memory still will not stable OC to the 1866 speed as described despite the upgrades.

 

Please advise if I am missing something obvious
