CPU Core Voltage 0V!

[Joe Schofield]

New PC Build with BIOS stating CPU Core Voltage as 0V brought me to HWINFO. Trying to understand if there's an issue with my motherboard by using HWINFO.

Build: 9800x3d, Asus x870e HERO, NZXT C1500 power supply, NZXT 360mm AIO
BIOS updated to one only a week ago. (version 1003)

Both the BIOS and the Armory Crate report the CPU Core Voltage as 0V.
I'm trying to understand where to find that same information in HWINFO64. I'm using the latest beta 8.21-5465.

I think these are the relevant areas:
Under Sensor Status:
CPU [#0]: AMD Ryzen 7 9800X3D: Enhanced
CPU VDDCR_VDD Voltage (SVI3 TFN). Current = 1.003V
CPU VDDCR_SOC Voltage (SVI3 TFN). Current = 1.025V (seem static, not jumpy like VDDCR_VDD)

ASUS ROG CROSSHAIR X870E HERO (Nuvoton NCT6701D)
CPU SOC 1.030V

ASUS EC: ASUS
VRM Vcore Voltage (VOUT) 1.031V (jumps around a bit)
VRM SOC Voltage (VOUT) 1.023V

Also, I've been able to install Windows 11 on this PC. I haven't tried to overclock it yet. I'm trying to figure out this VCore 0V issue reported by both the ASUS BIOS and Armory Crate.

Have I looked in the right places in HWINFO64? I very much appreciate any help with this as I dread the idea of sending back the motherboard. Took me a whole day to get it installed and the wires cleanly routed. The last PC I built was 4 years ago, so I'm slow at it.

How can the CPU Core Voltage of a running CPU be 0V?
This can happen only on some core(s) that are currently not used (power-gated).

I agree. Do the items that I found in HWINFO appear to be the correct ones to verify that the BIOS must be incorrect?

For anyone that finds this thread later, I was able to completely resolve the issue by replacing the motherboard with another of the exact same model.
