Can I get more efficiency of this specific card (micron chip)
I tried almost every settings but it keep crashing .
This setting is very stable I need to lower the power a bit.
Any OC settings ?
switch the aggressive undervolting to on.
Try without DPM state. which miner are you using for this result?
I’m using phoenix miner, if I apply aggressive undervolt do I need to remove core voltage values ?
good. Micron are quite good memories. My card is with samsung and its RX 570 but its power hungry.
it works now on 95W with 1137 core , VDD 831 / VDDCI 800 Mem 2150 and i get 30.8
i can raise a bit but it will raise watts and there is no point.

This is what I can get from 6 saphire nitro pulse rx580 8gb with micron chip.
I have moded the bios with polaris bios editor one click timing patch.
I can get stable 34 mh/s with 90w on hiveos.
If you lower the clocks and and voltage you can get even less power usage.

Yes I can share my bios tomorrow but I don’t think it is a good idea to flash my saphire bios in your amd gpu even if they are both with the same micron chip.
Have you tried to make a custom bios for your gpus with polaris bios editor(one time click)? If you don’t know how, you can provide me the bios and i can make it and give it back to you, it is very simple… and then you can test it
