hello everybody,
I am desperate in finding a solution to my problem. I have several rigs with Nvidia 1070 cards that work perfectly and can be easily overclocked via simple-mining website. The problem is that when I try to overclock my AMD 580 and 570 cards instead, I get no result apart from changing the fan speed. So changing the power-stage and undervolting do not affect power consumption.
I need to solve the problem. I bought 800 units of XFX 580 XXX 8GB with hynyx and samsung memory and although I get 29mhs/s the rig power consumption is 1200W per rig of 6 GPUs. And this is so bad.

Try reducing your core clock. Undervolting in linux is not perfect. I get least power consumption in windows followed by ethos and then simplemining. Windows is hard to manage with multiple rig and ethos gives a slightly less hash rate. The only way to reduce power consumption is to reduce core clock. Reduce the core clock till the gain made by reduction in power consumption is equal to loss incur by hash rate reduction.
the fact is that I can't manage to get under 950W by playing with power stage and core clock and core undervolting without dropping to 16mhs and below.....
can you suggest me a setting that could work with my XFX RX 580 XXX 8GB?
my goal is to go under 700w per 28mhs
Only windows can give you 700w per 28mhs. I am running 6 rx 570 4 gb in simplemining at 900 and 7 rx 570 4 gb in windows at 880.
What about modifying the bios? The fact is that having 800 units of these GPUs (I am not kidding, 800 units) I need to be able to manage the whole thing without having to restart the rig from a crash once every day (maybe less, maybe more, it's windows). Can you imagine doing this for 130 rigs? Is there something I don't get or know that can solve the issue?
please
