This is the default settings.
Most other cards I can undervolt to 910 volt
This card requires 930 mv
Not only that,
I wonder what is P1, P2, P3, P4, p5, p6 and P7?
It seems that the only things that matter is P7 right?
If I change value of P2 - P6 my rig crash
After that the radeon settings is "restored"
However, I wonder what's exactly going wrong?
What should I do? Check event viewer in windows? what?
This is the setting that's stable. However, as you see from screen shot, things are strange for P2 - P6.

If I use this settings instead
It'll crash
