I believe this is wrong, either its just a bug and HWMonitor is wrong or something is verry wrong with your PSU/Motherboard voltage regulators lol.
I'm not sure that your 12v components e.g HDD would be able to run @ 9 volts.
It most likely its just a bug, CPU-Z showed that my E5400 was running @ 1,5v when I only bumped my vcore with 0,0150v lol.
