Here it is... Report from HWinfo and the debug file from the debug mode. Voltage isn't erratic btw, but moves like a normal reading would from time to time, varying by millivolts ( altho it hasn't in this sensor session, it stayed stable ).
What is it? I just assembled a i7 8700 non-k system and in the process of reducing voltages across the board for thermals and longevity and has been successfull with the VCore and VCCIO/SA and RAM voltage, but I can't find any info anywhere about a "VIN7" voltage setting. I tried fiddling around...
