--- Comment #6 from bednarczyk.pawel@outlook.com ---
just tried against the latest kernel git master with AMD's latest AMD GPU tree
baked on top of that and my voltage is still shooting up to 1200m when the card
raches P7:

OD_SCLK:
0:        852Mhz        800mV
1:        991Mhz        900mV
2:       1084Mhz        910mV
3:       1138Mhz        920mV
4:       1195Mhz        925mV
5:       1250Mhz        935mV
6:       1425Mhz        940mV
7:       1475Mhz        950mV
OD_MCLK:
0:        167Mhz        800mV
1:        500Mhz        850mV
2:        800Mhz        910mV
3:       1025Mhz        950mV
OD_RANGE:
SCLK:     852MHz       2400MHz
MCLK:     167MHz       1500MHz
VDDC:     800mV        1200mV


If I cheat and set P6=P7 as follows:

OD_SCLK:
0:        852Mhz        800mV
1:        991Mhz        900mV
2:       1084Mhz        910mV
3:       1138Mhz        920mV
4:       1195Mhz        925mV
5:       1250Mhz        935mV
6:       1425Mhz        940mV
7:       1425Mhz        950mV
OD_MCLK:
0:        167Mhz        800mV
1:        500Mhz        850mV
2:        800Mhz        910mV
3:       1025Mhz        950mV
OD_RANGE:
SCLK:     852MHz       2400MHz
MCLK:     167MHz       1500MHz
VDDC:     800mV        1200mV

then voltage stays at 950mV as it should. There's a problem somewhere when the
card switches to P7.
