Hi, see my current initial config for this mainboard attached (usage: simply place this file into /etc/sensors.d/ directory, and read its content for further steps). Awaiting addition into lm-sensors.org's Configurations database and/or further suggestions. Thanks! Andreas Mohr -- GNU/Linux. It's not the software that's free, it's you.
# lm_sensors configuration file for the EPoX 8K5A2+ motherboard # 2013-01-11, Andreas Mohr <andim2@xxxxxxxxxxxx> # Comments welcome! # # First version - # not yet fully confident about scaling factors, # slight remaining possibility of a labeling error, # mild testing only. # User ga.rp on "KT333 board Kaufempfehlung" # http://www.forum-3dcenter.org/vbulletin/archive/index.php/t-101395.html # says that according to EPoX, 8K5A2+ uses internal Athlon diode # for *internal monitoring* by overheating protection circuit only, # i.e. only the external socket diode is readable by sensors. # sensors-detect tries to detect an LM84, but it is not successful, # discards this sensor due to negative temperature values. # Manually loading adm1021 module and then running "sensors" # will display this negative output. # Due to ACPI occupying the resource range of the W83697HF, # in newer kernels enabling loading of w83627hf module requires the # acpi_enforce_resources=lax kernel parameter (warning, dangerous - # however I haven't observed any problems yet). # Not doing so will fail with following dmesg log: # ACPI Warning: 0x00000295-0x00000296 SystemIO conflicts with Region \IP__ 1 (20121018/utaddress-251) # ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver chip "w83697hf-isa-*" # Labels used by (sorting temp/RPM/others): # BIOS Health screen: # System|CPU|CPU|CHASSIS|Vcore|Vagp|+ 5 V|+12 # V|Vio|VDIMM|VBAT(V)|VSB(V) # Bootup screen: # Chassis|CPU|Vio|Vcore|Vdimm|Vagp|Vbat|12V|5VSB # Since they are different, decide to use the common EE convention of # lower-case attributes. # Temperature # external socket diode (not the Athlon XP internal diode) label temp1 "CPU" label temp2 "System" # Fans label fan1 "CPU" label fan2 "Chassis" ignore fan2 # TODO_USER comment this if you have a chassis fan # Voltage label in0 "Vcore" label in1 "_in1" # WTH is this??
