Hello 'Shmerl',

can you (and the other) please recheck with 'auto', too?
I think we have the 'same' problem with Polaris, too.
If one set low/high it is set @fixed frequency and NOT @ the 'flickering'
'auto' mode.

I can't test the 'suspend / resume' cycle 'cause my server/workstation do NOT
work reliable on it.
But power consumption is definitely to high on Polaris, too.

@Alex: What do you think about this?
