ASRock X99 Fatality CPU voltage adjustment question

[H2mike]

I have a ASRock X99 Fatality motherboard with a 6850K cpu.
I can't find anywhere in the Bios how to adjust the CPU vcore voltage. Can someone help me with this?
Voltage Configuration:
CPU Input Voltage
CPU Load-Line Calibration
Dram Voltage
Dram Activating Power Supply
PCH PLL Voltage
CPU I/O Voltage
ME Voltage
PCH Voltage

I can't see anywhere to set a CPU Voltage of say 1.35
I have it overclocked to 4200MHz using the easy mode, but at 4300MHz it fails Prime 95 after 2 hours. I want to bump the voltage up to 1.35
My temps at full load are about 64C.

I found out how to do it!
There is a section called FIVR Configuration and it is in that section. I had never seen that before. I kept looking in the Voltage Configuration area. Sorry for asking a dumb question. It seems stable now at 4400 Mhz so far.
