Compare it with my posts about the X8SAX/C7X58 and the config file that
resulted from it, and you will be able to extrapolate the correct config
file for the 7046T-NTR+.

The supermicro-supplied data is in the list archives, and the final
config file is in the lm-sensors site (and probably in the list archives
as well).

Thanks for the info provided by all in this thread.
w83795.c compiled and installed (64bit)  --  and
combined with the appropriate new  conf (based on X8SAX/C7X58 conf )
I now have meaningful temp and fan readings.   Much appreciated.
Till Ubuntu gets up to  2.6.37 I'll probably have to redo the process
(beginning with recompile)  with each new kernel, but that is fine.

Thanks again.

This tells you that the board uses a Winbond W83795 chip (not sure which one
exactly, as I know of two variants "G" and "ADG" and they told you
"AG" which I don't think exists...) for hardware monitoring. This
device is supported by "my" w83795 driver, which is available since
kernel 2.6.37 or as a standalone driver at:
  http://khali.linux-fr.org/devel/misc/w83795/

More specifically, the above data, together with the w83795 source
code, tells you how to write a libsensors configuration file for your
board. To make your job easier, I have documented the mapping between
pins, symbols, registers and sysfs entries:
  http://lists.lm-sensors.org/pipermail/lm-sensors/2011-January/031163.html

Apparently you managed to write a configuration file already, this
document should help you confirm if you got it all right or not.

This can't work, as the chip will be named w83795adg-* or w83795g-* by
libsensors.

This is extremely unlikely. Scaling factors are never less than 1.0.

There is some inconsistency here. A W83627DHG-P chip would be named
w83627dhg-* by libsensors, not w83627hf-*.

It's more efficient to just not load the w83627hf (or w83627ehf) driver
on this board.

[Henrique de Moraes Holschuh]

Here is the latest version of my C7X58 config, for reference.  I did
have to ask supermicro for clarifications, to derive a correct formula
for in5.  The first data they sent was bogus.

It is in fact a     w83795adg    as reported by dmesg.
The supermicro folks had a typo in what they sent me, as you suggested 
earlier.

  They also sent
+12V Voltage, Offset 0x14        Voltage = Data* 0.008/ (10./66.2)
which I had as
    compute in4 @*(10.0/66.2), @/(10.0/66.2)
Aha. Notice I misread what they sent me.     They used  '/   /' and I 
used '*  /'.
My reading of the algebra was careless.

So I switched to Henrique's equation which is an accurate representation:

    compute in4 @*6.62, @/6.62

which gives a more sensible output (11.94 volts).


Thanks again for all the help.
David Anderson
