The actual reading is 1.07V, and if I change the CPU Vtt Voltage in
the BIOS, the value also changes according.
The same feature was in discussion on the AIDA forums [1] for almost
the same mainboard.

As I installed the mainboard I found the factor in the wiki [2] from a
board with the same hwmon chip. With this my BIOS and lm-sensors
readings matched (BIOS: 3.304, lm-sensors -u: 3.305) So I did no
further investigations.
But now since you asked my I tried to accept the challenge ;-) Sadly
I'm very confused now.. I tried to find as many 3.3V BIOS readings
from the same or similar boards and found the following:
U [V] U_Delta [V] Ref URL
3.284
3.304 0.02
3.324 0.02
3.344 0.02 [3]
3.363 0.019 [4]
3.383 0.02
3.423 0.04
Very confusing measurements, especially the step after 3.363V upwards!
With all these measurements I assumed a 0.02V step in the reading and
calculated the factor (20 / 12) which leads to an too high reading
(3.340 instead of 3.304V)
With an assumed step of 0.019V the reading is to low (3.173V instead
of 3.304V)
Calculated reverse the BIOS reading and the unscaled lm-sensors output
(3.304*12/2.004) I get an (19.78 / 12) factor which leads me to an
almost corresponding reading to the BIOS value in sensors (3.303V)
But the scale seems to have an strange stepping anyway.. Have you seen
this before?

You're right, my fault.
set in7_min 3.3 * 0.95
set in7_max 3.3 * 1.05
Actual reading here in7_input: 3.384

Yes it is.

I monitored these temperatures after a cold boot and this value seems
to match the "System temperature" in the BIOS health status.
label temp1 "System temp"
set temp1_min 10
set temp1_max 60
>> ignore temp2 label temp2 "MB temp??" # shows always 25°C set
>> temp2_min 0 set temp2_max 60
Checked this temp again. Found that on the GA-Z77X-D3H this is PCH
temperature. On this board it has also an BIOS reading for it, I dont.

Thank you!
