# lm-sensors configuration for the ASUS PRIME Z370-A motherboard
3
# Manufacturer: ASUSTeK COMPUTER INC.
4
# Product Name: PRIME Z370-A
7
# UEFI versions tested: 0805, 1601
9
# Recommended drivers: coretemp, nct6775
10
# Other Z370 boards from ASUS might use a similar setup
12
# dmesg might show that the kernel failed to bind the nct6775 driver due to an
13
# ACPI conflict between SystemIO and OpRegion ranges. Ideally a WMI driver
14
# should be used instead of directly accessing the Super I/O chip but,
15
# unfortunally, very little is exposed via WMI, even on the latest UEFI.
17
# You can allow the driver to bind to the chip, regardless of the conflict, by
18
# setting the kernel command line option:
20
# acpi_enforce_resources=lax
22
# This is not known to cause issues on the PRIME Z370-A, but you might still
23
# want to disable thermal and blacklist eeepc_wmi to minimize conflicts:
25
# thermal.off=1 module_blacklist=eeepc_wmi
