Question Monitoring software can't read 4080 voltage/power ?

Recently purchased a Gigabyte 4080 Gaming OC card and it works as advertised, but the voltage and power sensors are all reporting 0 in every hardware monitoring software I try. I have tried reinstalling drivers and windows, updating my motherboards bios (Z690 A Rog Strix bios version 2305) but that hasn't fixed the problem. There only appears to be one vbios for this card, so I can't test any other versions. My previous graphics card still shows voltages when it's connected. I've also tried using the nvidia 1.2 firmware update, but the card came with it installed already.

I've made sure that the "Unlock voltage monitoring" setting is enabled in MSI Afterburner, but still nothing. I can only find one other person with this issue on the techpowerup forums https://www.techpowerup.com/forums/...g-power-or-secondary-voltage-readings.306659/ so I'm not sure if this is leaning towards a hardware or software problem. Power supply is a Corsair RM850x 2019 version. The 4080 is connected using 3 x PCIe power cables, but one of them is daisy-chained. I've been told this is okay to do with this power supply. Any ideas or suggestions would be greatly appreciated. Thanks.

I've lost voltage control on my msi suprim x 4080 - I had it before, but something recently, maybe a driver update, has just cut it out and lost it completely.
 
I've just fixed this.

Uninstall msi afterburner.

Install https://www.guru3d.com/files-details/display-driver-uninstaller-download.html DDU, display driver uninstaller.

Run MSConfig and tell windows to boot into safemode.

Reboot, run DDU and use it to 'uninstall and reboot' your graphics driver.

Run msconfig and tell it to boot into windows normally. Reboot.

Download the latest nvidia driver https://nvidia.custhelp.com/app/answers/detail/a_id/5455

Download the latest msi afterburner beta https://www.guru3d.com/files-details/msi-afterburner-beta-download.html (riva tuner stats doesn't seem to work on windows 11 atm for some reason, at least for me, so maybe don't install that).

All should be well again.

I was already using this version of msi afterburner, but I'll try your steps and report back.

EDIT: Nope, still nothing. I can't even see any power information using the geforce experience overlay. It just says 0 watts.
