Tested on a Ryzen 7 2700 (patched on top of 5.4.13):

| k10temp-pci-00c3
| Adapter: PCI adapter
| Vcore: +0.80 V
| Vsoc: +0.81 V
| Tdie: +37.0°C
| Tctl: +37.0°C
| Icore: +8.31 A
| Isoc: +6.86 A

Like the 1300X case I see a discrepancy compared to what the nct6779
driver says Vcore is:

| nct6779-isa-0290
| Adapter: ISA adapter
| Vcore: +0.33 V (min = +0.00 V, max = +1.74 V)
| in1: +0.32 V (min = +0.00 V, max = +0.00 V) ALARM
| AVCC: +3.39 V (min = +0.00 V, max = +0.00 V) ALARM
| +3.3V: +3.39 V (min = +0.00 V, max = +0.00 V) ALARM

| in5: +0.82 V (min = +0.00 V, max = +0.00 V) ALARM
| in6: +0.30 V (min = +0.00 V, max = +0.00 V) ALARM
| 3VSB: +3.42 V (min = +0.00 V, max = +0.00 V) ALARM
| Vbat: +3.25 V (min = +0.00 V, max = +0.00 V) ALARM
| in9: +0.00 V (min = +0.00 V, max = +0.00 V)
| in10: +0.22 V (min = +0.00 V, max = +0.00 V) ALARM
| in11: +1.06 V (min = +0.00 V, max = +0.00 V) ALARM
| in12: +1.70 V (min = +0.00 V, max = +0.00 V) ALARM
| in13: +1.04 V (min = +0.00 V, max = +0.00 V) ALARM
| in14: +1.79 V (min = +0.00 V, max = +0.00 V) ALARM
| fan1: 0 RPM (min = 0 RPM)
| fan2: 1708 RPM (min = 0 RPM)
| fan3: 0 RPM (min = 0 RPM)
| fan4: 0 RPM (min = 0 RPM)
| fan5: 0 RPM (min = 0 RPM)
| SYSTIN: +33.0°C (high = +0.0°C, hyst = +0.0°C) ALARM
| sensor = thermistor
| CPUTIN: -62.5°C (high = +80.0°C, hyst = +75.0°C)
| sensor = thermistor
| AUXTIN0: +79.0°C sensor = thermistor
| AUXTIN1: +96.0°C sensor = thermistor
| AUXTIN2: +23.0°C sensor = thermistor
| AUXTIN3: -22.0°C sensor = thermistor
| SMBUSMASTER 0: +39.0°C
| PCH_CHIP_CPU_MAX_TEMP: +0.0°C
| PCH_CHIP_TEMP: +0.0°C
| PCH_CPU_TEMP: +0.0°C
| intrusion0: ALARM
| intrusion1: ALARM
| beep_enable: disabled

I suspect the nct6779 is not reporting correctly (or needs some
configuration) here, as I see that's what Ken is using with his 1300X as
well.

(ASRock B450M Pro4 motherboard, fwiw.)
