My C0 bios settings are:

Vcore - 1.325 (can't lower anymore)
QPI/VTT - 1.24
CPU/PLL - 1.84
Dram Voltage - 1.64
Hyperthreading - On
All other volts - AUTO
All Power Saving features Off
Turbo Off

Temps: 40 idle, 74 Max Load OCCT, 76 Max Load Linx (office w/ AC).

Tested @ OCCT w/ HT on: 4 hours Small Data Set, 1 hour Large Data Set, 1 hour & 30 Medium Data Set. = All Passed
Tested @ Linx Full Memory 20/20 = Passed

It's stable yes, but i searched somewhere i need to raise my qpi/vtt? i am actually confused. Also someone said if you set your qpi/vtt to 1.35 then you can run drams up to 1.85volts right? if you run 1.24 qpi/vtt it means i can run drams up to 1.74volts? so my settings are correct?
