It's not the cpu. http://valid.canardpc.com/4w4pia
The motherboard bios obviously changes settings based on microcode the cpu has, that's how it knows where to set clockspeeds and voltages for a particular processor.
In this case, I think MSI probably wanted to protect the board by locking the voltages in bios. You can still push up to 2volts plus using command center however.
I ran Prime95 at default speeds and voltages on the FX9370 - no problems after half hour so I upped the frequency to 4.5 ,then 4.6 each for a half hour. When I tried 4.7ghz on all cores, core 5 failed at about 28 minutes, this was without adding any voltage.
