Does anyone here have the 'Eco Bios' for R9 Fury and Rx 480 cards? I don't like using wattman or software to get power draw down and would prefer to flash bios for lowest possible power consumption at stock clocks or close to.
I just use the miner to set voltage and clocks, really easy, and flexible, since different algorithms have different optimal clocks and undervolts.  The Eco bios isn't undervolted, it is just lower clocks (lower volts, but still stock).  You can easily undevolt another 50-100mv+ and save tons of power. I use CM, but SGM/GG supports all that stuff right?

I am mostly looking to undervolt to run Fury/480 at low power to squeeze 6 cards into a 1300w PSU so I'd have to load it on Bios level no?

Not sure about getting to work on Linux, but you can undervolt 6 470s, stock 1260 clock, and run ~930W at wall Zec mining (CM 11.1, Platinum PSU, ~1020mv), 480s would be ~1000 or so at wall.  Underclocking allows substantial undervolting, but affects Zec speed, I dual mine Eth/Dcr right now so not as much of an issue.

If you can't change volts in Linux on 480s, in Windows, use atiwinflash to pull bios, edit voltages with polarisbioseditor, the reflash. Dunno about Linux flashing/editing tools.  What cards do you have?  If there is dual bios, there is usually a "silent" bios.

Running 6x480s overclocked, 1050w at wall in most of my rigs, overclocking is fun! Smiley
