Asus X570 mainboard sensors issues.

Hi All

I installed a new computer with opensuse Tumbleweed 20200112.
I have been updated sensors to 3.6 and sure super IO chip NCT6798D be found.
but I still can’t get fan speed and core temperature and voltage.
I only got Tdie and Tctl.

Does the issues comes from BIOS or just the X570 or mainboard too new ?

Appreciate for your kindly help.

sensors-detect version 3.6.0

Board: ASUSTeK COMPUTER INC. Pro WS X570-ACE

Kernel: 5.4.7-1-default x86_64

Processor: AMD Ryzen 9 3950X 16-Core Processor (23/113/0)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you’re doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don’t find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Probing for IPMI BMC KCS' at 0xca0... No Probing for IPMI BMC SMIC’ at 0xca8… No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): yes

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Hi and welcome to the Forum :slight_smile:
If you fire up YaST bootloader and add the following kernel command line option;


acpi_enforce_resources=lax

Save and reboot, does this help?

Thank you, I have been tried acpi_enforce_resources=lax on the grub.cfg but not working.

but it is working as you guide line add with YaST bootloader . Thank you so much !!
