what's your CPU? does clear CMOS helps and did you install the latest version ryzen master? I'll suggest to check with 3rd party software too such as HWinfo or just Dragon Center.

Hi, thanks for your reply, CPU is Ryzen 3600, yes I did install latest version of master but have not cleared cmos since bios update(will try later) Am using 3rd party temp checker at the moment.

What bios version did you flash - the latest stable or beta bios? I remember somebody else having sensor issues after flashing beta bios...

I've reported this issue to MSI via a ticket and made a post on here already.

When you do a fresh flash of bios 7c84v163 the temperature sensor 'CPU Die (Average) disappears - this is the sensor Ryzen Master reads from. Starting from a freshly flashed bios which is still at the default settings, the fix is to change a setting (turn on your memory XMP profile for example) so that you are able to then re-enter the bios on reboot and load the optimized default settings (if you don't change a setting beforehand, the BIOS will say that the default settings are already loaded). The board will then function as normal thereafter.

Same issue with BETA BIOS 1.63 on MSI MAG X570 Tomahawk Wifi and Ryzen Master on my system with Ryzen 9 3900XT. I know of one user with Ryzen 9 5950X reporting the same. Zen Timings 1.2.3 starts with the error message "could not get power table". In HWiNFO several values are missing when compared to BIOS 1.50 or even 1.61 BETA.

I have reported in detail here.

Thanks for your feedback. :biggthumbsup:

I didn't do anything like that. But after a simple "Restore defaults" and again manually setting my preferred values in the BETA BIOS 1.63 (this time in two steps, but without a difference) the errors described in Ryzen Master, Zen Timings and HWiNFO have all disappeared (see here).

I usually do "Restore defaults" before an update. I don't know why that worked now. Anyway, now I am waiting for the final version.
