Hi Guenter,
Thanks a lot for the additional information. The following is interesting.
-0x059960: 00000000 08400001 00004623 00000039 +0x059960: 00000000 08400001 00008241 00000045
The last two blocks also temperatures. In the AMD thermal code, we find definitions for CG_MULT_THERMAL_STATUS and CG_THERMAL_RANGE. The first consists of 2 x 9 bit (0x23 and 0x43 above for idle and under load), the second is just a value. On Zen2, the address for those values is 20 higher (0x05997c instead of 0x059968), but the numbers are pretty much the same. The AMD thermal code reads those values for some graphics chips and displays it directly in degrees C. I am just not sure what exactly it represents. I see those temperatures on 3900X as well. Actually, it looks like all chips report them, including server chips, so it is not the graphics temperature. But it is definitely worth keeping an eye on it; maybe someone can figure out what it is.
Hope this is not a waste of your time.
No, it is definitely worth it. It will give me data to work with in the future.
Would you like similar for the 2500u ?
Yes, that would be great. Thanks, Guenter
