I'm telling VRM to send lower voltage to ASIC with -0.0439.
The VRM is tired, he likes it.
ASIC likes it too.
If they likes it I likes it.

Look closely @ the default voltage
-0.0366.
IT IS A NEGATIVE NUMBER
-0.0439
is a MORE NEGATIVE NUMBER

The way it is set up, there is a default voltage that is close.
Then add or subtract from that to get what you want.

Try higher/lower and see what works for you.

YMMV
