One of my card requires unusually high voltage

[pornluver]

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

p1 - 7 are the power state... according to the work load cards change frequency and the voltage... you dont have to modify the voltage but better give a voltage offset. NOT EVERY CARD OF THE SAME KIND REQUIRES SAME VOLTAGE

What is power state? When does the program decide that it should enter one state and not the other? By GPU load?

What is a voltage offset? Why it's better to give a voltage offset than to modify the voltage directly?

I am aware that different cards require different voltages.

I check windows viewer I see
