790FX chipset features

[Rapidwire]

The AMD 790FX supports Advanced clock calibration (ACC). Am I correct this feature has no benefit to Phenom II X4 CPUs since their cores are already unlocked?

Also, that same chipset supports AutoXpress. I know that the MemBoost feature of AutoXpress works for DDR2 memory, according to the the Wikipedia article: http://en.wikipedia.org/wiki/AMD_700_chipset_series#AutoXpress. Does MemBoost have any effect on DDR3 memory?

Thanks.

ACC allows the overclocker better control over the whole setup, whether the cores are locked or not.

Thanks for the reply. Does anyone have an answer to the AutoXpress question I asked?
