[lm-sensors] Config file for Gigabyte MA785GM-US2H

Here's a config file I worked up for the Gigabyte MA758GM-US2H.  It's
based off of one taken from your web site. This is NOT confirmed by
examination of the MB, just by observed readings.

Yours,

Glen Journeay

Out of curiosity, which configuration file did you start from?

Please follow ISO-8601 for dates, otherwise it's ambiguous. I read the
above as December 8th, withe you certainly meant August 12th.

This is inconsistent. You just said that Vcore didn't need any scaling,
yet you have a compute statement for Vcore. In all honestly, I would be
very surprised if it were correct... Vcore is never scaled, it doesn't
need to (it's way below the +4.08V limit.) How did you come up with it?

Would be more intuitive to leave them in order.

You're setting temp3_max twice, and you're never setting temp2_max.

Jean,

Sorry for the late response.  I based this off of a file called
sensors-Gigabyte-965P-DS3.conf taken from here:

http://khali.linux-fr.org/devel/lm-sensors/sensors-Gigabyte-965P-DS3.conf

I found the reference here:

http://www.lm-sensors.org/ticket/2273


Sorry about the date, and not correcting the comment about scaling,
although I have to admit, scaling in0 is dubious.  I did it to make the
lm-sensor readings match the BIOS readings, but the BIOS reading is
somewhat high for an Athlon II X2 245 which should be 0.85 to 1.425 V
from the specs I can find on the web.  Thanks for also pointing out the
errors in setting the temp limits, I did bang this one out rather
quickly.  Plus, I'm still not sure exactly sure what components the
temps are really reading.

I've attached an updated file.

Glen

I updated the wiki, thank you!
