R9 390 Nitro TRI-X 8GB - Anybody has a modded BIOS for this card - zcash mining
Or is there a tutorial out there. I'd like to have less Power consumption.

Is it voltage locked? Windows? AB (-100mV) or Trixx (-200mV) doesn't work?

No i can adjust the voltage in TRIXX but when i try -100 my screen turns black. So maybe i need to mod the bios ?

Default clocks, -100mV and black screen? If DDU and latest drivers doesn't help then you have lost in silicon lottery, basic bios modding doesn't help. Every 300 series hawaii I have seen should have been -100mV from factory IMO.

No default is 1010 and 1500. I'm trying 1100 and 1600.
1100 and 1500 and -100 works.
Which setting should i de for optimal hash/Watt.
And shouldnt i need a bios mod...

1100/1500 is a good basic performance setting for every algo, 30+ dagger, 900+ cryptonight, 400+ equihash. Cryptonight and equihash get some boost if you play with straps and memory clocks.
For optimal hash/ watt with 390 you need to underclock. With your card, set your mem to 1250 and try gpu clocks 698, 858, 899, 935 and 969. When you find a combination you can live with try to undervolt, trixx does -200mV. Gpu volts in 0.85-1.00 area normally give you the best efficiency.
You need to try it yourself, there is no easy answer to your question.

I would be very surprised if there is an easy tool for hawaii, could be wrong though.
Start with hex editor and just do an easy strap copy and see where that goes.

I've never used something like that and i'm afraid i'd Mess up my card or use wrong setting. Ill try the underclock first. U said 0,85 - 1 ?
Does that Mean -85 to -100? In TRIXX
Thanks

Trixx - hardware monitor - vddc. You need to find a way to get that below 1.0V to be efficient. |

I could be wrong but I think Your card has Dual-BIOS. Pretty safe to do BIOS flashing thanks to that!  |

I think something is wrong with my card.
Whenever i even adjust the slider of the voltage in TRIXX.
Screen falls out. I tried to play a game. And the game freezed aswell. Computer is also acting up. Chrome not responding. Apps take Longer to open.
I DDU'ED and installed latest drivers. Did a driver check. Installed ALL older drivers.
Problem still persists. Using 2 different bios.
Is it a GPU problem of maybe mobo ?
