Overclocking Individual Cores

Is it possible to overclock individual cores? It seems like there is a difference of a couple hundred mhz between what each core can achieve. I'm running a FX-8320 @1.35v and using OCCT for stability testing while using task manager to set affinity.

Core #0- 3.9ghz
Core #1- 4.0ghz
Core #2 - 4.2ghz
Core #3 - 3.8ghz
Core #4 - 4.2ghz
Core #5 - 4.2ghz
Core #6 - 4.1ghz
Core #7 - 4.0ghz

I can't achieve more than a 3.8ghz OC because of Core #3. At 4.2, the core temps hit a max of 60 degrees after a hour of stress testing but continuously return errors so I want to hit the max multiplier on each of the cores. Is this even possible?

Thanks guys

I believe AMD's Overdrive will let you o/c each core in Windows.

Guess I'm wrong, kinda weird though. I wonder how multithreaded programs react to cores performing at different levels.
