Hi, I've got an asrock b650i motherboard, the manual says it has an NCT6686D chip. Is ther a method to detect this chip? uname -a Linux athene 6.6.13-1-lts #1 SMP PREEMPT_DYNAMIC Sat, 20 Jan 2024 14:48:01 +0000 x86_64 GNU/Linux modprobe nct6683 [ 4.866999] nct6683: Found NCT6686D or compatible chip at 0x2e:0xa20 sensors k10temp-pci-00c3 Adapter: PCI adapter Tctl: +41.4°C Tccd1: +30.5°C nvme-pci-0100 Adapter: PCI adapter Composite: +31.9°C (low = -0.1°C, high = +85.8°C) (crit = +87.8°C) Sensor 1: +31.9°C (low = -273.1°C, high = +65261.8°C) mt7921_phy0-pci-0700 Adapter: PCI adapter temp1: +30.0°C amdgpu-pci-0c00 Adapter: PCI adapter vddgfx: 760.00 mV vddnb: 1.28 V edge: +39.0°C PPT: 29.00 W sensors-detect # sensors-detect version 3.6.0+git # System: ASRock B650I Lightning WiFi [Default string] # Kernel: 6.6.13-1-lts x86_64 # Processor: AMD Ryzen 7 7800X3D 8-Core Processor (25/97/2) 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. Do you want to scan for them? This is totally safe. (YES/no): Silicon Integrated Systems SIS5595... No VIA VT82C686 Integrated Sensors... No VIA VT8231 Integrated Sensors...

(YES/no): Probing for Super-I/O at 0x2e/0x2f Trying family `National Semiconductor/ITE'... No Trying family `SMSC'... No Trying family `VIA/Winbond/Nuvoton/Fintek'...

No Trying family `ITE'... No 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): 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): Probing for `National Semiconductor LM78' at 0x290...

No 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/selectively): Sorry, no sensors were detected. Either your system has no sensors, or they are not supported, or they are connected to an I2C or SMBus adapter that is not supported.
