<pre>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.</pre>
