This configuration has been tested on a Supermicro X7SLA-H motherboard which uses an Intel Atom 330 CPU. This configuration should be compatible with the Supermicro X7SLA-L motherboard since both variants have 3 fan headers and the same Winbond 83627ZDHG-P Super I/O controller chip. The X7SLA-H motherboard is used in their "SUPERMICRO SYS-5015A-H 1U Barebone Server". Supermicro has their own "SuperoDoctor II" software for Linux. The following is the output from the "sdt" command included in that software: [root@fatman ~]# sdt ***************************************************************************** Supero Doctor II - Linux version 2.71(100409) Copyright(c) 1993-2010 by Super Micro Computer, Inc. http://supermicro.com/ ***************************************************************************** Monitored Item High Limit Low Limit Status ---------------------------------------------------------------------- Fan1 Fan Speed 712 1231 Fan2 Fan Speed 12053 0 Warning!

I determined through experimentation that the "AVCC" value from the "w83627dhg-*" section of "sensors3.conf" with label "in2" is a "+3.3 Voltage" input. Changing values related to "in2" affected the "+3.3V Voltage" line in Supermicro's "sdt" command. Thus I figured that "in3" is the line used for "+12V Voltage" in "sdt". The compute line seems accurate and the formula was based on info found on the LM_Sensors Wiki for another chip. It appears there are 2 separate inputs, "in1" and "in4", for measuring DIMM Voltage. The motherboard has 2 DIMM sockets. Removing a DIM from "DIMM_B" did not affect the voltage read by either "in1" or "in4" suggesting that either input could be safely ignored. I ignore Temp3 since it displays negative temperatures even though it is located in a room with an ambient temperature of 78 degrees Fahrenheit. _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
