I think i should post this here, too. Everything the Polaris Bios Editor can change, well, except vram timings, is also to be found in "PP_PhmSoftPowerPlayTable".
It is a 1:1 copy of the PowerPlayTable found in the bios. Therefore PBE was a big help, i only had to compare bios files.
U don't need a signature, don't have to flash your card, and it works just the same as a real bios mod.
I used a reference RX 480, XFX Black Edition. Should work with any other Polaris card.
Install MSI Afterburner
Goto Settings -> General -> AMD Compatibility properties -> activate "Extend official overclocking limits".
This will create the registry entry "PP_PhmSoftPowerPlayTable" at:
last 4 digits may vary due to crossfire or whatever..
Save the reg key (the four digit thing, right click -> export) and delete anything except "PP_PhmSoftPowerPlayTable":
U can now make your changes here, or use regedit.
the maximum power limit increase. +50% -> hexadecimal: 32
FF08 (65288) is for P7 state, P6 FF07.. search for 08 FF instead, and here we are, all values from 800 to max as found in polaris bios editor:
these^^ are the exact same values, the polaris bios editor would change.
example: 1200mV -> hex: 4B0 -> B0 04 instead of 08 FF (P7)
don't make a mistake here
If u don't change this byte from 0F to 0B, memcontroller voltage will be the same as vcore.
Some customs have this value already set, else i wouldn't know about it.
clocks for each p-state are found here.
1400MHz x100 -> 140000 (dec) -> 222E0 (hex) -> E0 22 02 (bytes)
TDC(A) and max power limit (W) is found here:
110A (hex:6E) TDC and 115W (hex:73) max power limit (XFX Black Ed.)
vram clockrate, again x100:
200000 = 30D40 -> 40 0D 03
^^these values also can be found:
1000 = 3E8 -> E8 03, followed by the frequencies.
30 75 ->7530 hex -> 30000 (300MHz x 100)
Temp Hysteresis: 3
min Temp: 40° x100 = 4000 -> FA0 -> A0 F0
med Temp: 65° x100 = 6500 -> 1964 -> 64 19
high Temp: 85° x100 = 8500 -> 2134 -> 34 21
min PWM: 20% x100 = 2000 -> 7D0 -> D0 07
med PWM: 40% x100 = 4000 -> FA0 -> A0 0F
high PWM: 60% x100 = 6000 -> 1770 -> 70 17
max Temp: 109° x100 = 10900 -> 2A94 -> 94 2A
max PWM: 100% -> 64
Sensitivity: 4836 -> 12E4 -> E4 12
max RPM: 2200 -> 898 -> 98 08
Acoustic Limit: 910MHz x100 = 91000 -> 16378 -> 78 63 01
