Description:
|
|
------------
|
|
ASUS mainboards publish hardware monitoring information via WMI interface.
|
|
|
|
ASUS WMI interface provides a methods to get list of sensors and values of
|
|
such, which is utilized by this driver to publish those sensor readings to the
|
|
HWMON system.
|
|
|
|
The driver is aware of and reads the following sensors:
|
|
* CPU Core Voltage,
|
|
* CPU SOC Voltage,
|
|
* DRAM Voltage,
|
|
* VDDP Voltage,
|
|
* 1.8V PLL Voltage,
|
|
* +12V Voltage,
|
|
* +5V Voltage,
|
|
* 3VSB Voltage,
|
|
* VBAT Voltage,
|
|
* AVCC3 Voltage,
|
|
* SB 1.05V Voltage,
|
|
* CPU Core Voltage,
|
|
* CPU SOC Voltage,
|
|
* DRAM Voltage,
|
|
* CPU Fan RPM,
|
|
* Chassis Fan 1 RPM,
|
|
* Chassis Fan 2 RPM,
|
|
* Chassis Fan 3 RPM,
|
|
* HAMP Fan RPM,
|
|
* Water Pump RPM,
|
|
* CPU OPT RPM,
|
|
* Water Flow RPM,
|
|
* AIO Pump RPM,
|
|
* CPU Temperature,
|
|
* CPU Socket Temperature,
|
|
* Motherboard Temperature,
|
|
* Chipset Temperature,
|
|
* Tsensor 1 Temperature,
|
|
* CPU VRM Temperature,
|
|
* Water In,
|
|
* Water Out,
|
|
* CPU VRM Output Current.
|
|
|
|
Known Issues:
|
|
* The WMI implementation in some of Asus' BIOSes is buggy. This can result in
|
|
fans stopping, fans getting stuck at max speed, or temperature readouts
|
|
getting stuck. This is not an issue with the driver, but the BIOS. The Prime
|
|
X470 Pro seems particularly bad for this. The more frequently the WMI
|
|
interface is polled the greater the potential for this to happen. Until you
|
|
have subjected your computer to an extended soak test while polling the
|
|
sensors frequently, don't leave you computer unattended. Upgrading to new
|
|
BIOS version with method version greater than or equal to two should
|
|
rectify the issue.
|
|
* A few boards report 12v voltages to be ~10v.
