Subject: Re: NCT6775F driver

OK, so I checked in BIOS, and its not clear what the right mapping is.... this is what I had in BIOS (in order)

+12V = 12.14V   (min = 11.1, max = 12.9 )

+5V = 5.19V      (4.6 - 5.4 )

+3.3V = 3.40V     ( 3.0 - 3.6)

Memory VCC = 1.58  (0.4 - 2.0)

Process Vcc = 1.15 (0.6 - 1.6)

PCH Vcc = 1.07 (0.6 - 1.6)

+3.3V Standby = 3.42 (3.0 - 3.6)

Not sure how these (7) map to the (8) that are shown in the sensors output - the orders or names don't seem to line up.

Any help?

Thanks,

Scott

Agreed, that is unlikely. Most likely your sensors.conf entries, specifically the
multiplication factors, are wrong. Try to run sensors -u to see the raw output.

Possibly you need to repeat the command a couple of times, to make the alarm go away.

And what does sensos show without any calculation factors for voltages?
