HWMonitor & CPU Cache Voltage

I believe I have a stable overclock on my 5960X @ 4500mhz. I am now trying to OC the CPU cache ratio and need to up the voltage for it. I am using Offset Mode so that it will adjust with load. I want to monitor what the actual total voltage is in HWMonitor 1.27, However, I'm not sure what it is listed as, if at all. I see listings for VIN3 & VIN4. Is it one of those?

Thanks

Are you running on ASUS X99-E WS? My friend has the same one, I could check

Yes, Asus X99-E WS.
I believe I figured it out. HWMonitor displays the CPU Cache Ratio voltage as LLC/Ring with it set to a manual value, or Ring Offset when set to an offset value.
