Also if I may, (if this thread isn't the place to ask for ethOS technical advice please let me know, but I am dying to ask for some help from the concentration on smartest people on the subject) - would anyone be willing to help me with the overclocking of two dissimilar AMD cards ( 1 4gb ellesmere rx 570 113-2e366fu-o53 elpida (edw4032babg) and 1 8gb ellesmere rx 480 113-d0090101-100 samsung (k4g80325fb) and I I'm only getting about 23.5 Mh/s. Other vitals posted in screenshot. https://ibb.co/dW8Oeb

I've attempted overclocking the cards independently and can't seem to single them out for their specific instructions (I've tried matching by BIOS, ect)

Could someone AMD familiar post me an example config to attempt. I feel like I'm not using these cards effectively.

Thank you so much if you're able to help.

I too am struggling with this. I've been googling for my gpu bios and then copying what other ethosdistro folks have done. For example, i'm running 7 -- rx 570 (113-57045EHB1-W90 Elpida)

I found this...

Code:

# FROM: http://lhmach.ethosdistro.com/?bios=yes
# rig: loc: lhm200 -- 7a2a69

#cor 113-57045EHB1-W90 1080
#mem 113-57045EHB1-W90 1970
#pwr 113-57045EHB1-W90 2
#vlt 113-57045EHB1-W90 940

I tried this out and I do get about 22.50 MH/s per card. Unfortunately, two of my seven cards are unstable at this setting and after about five minutes it starts going all over the place. I've checked and double checked power, risers, etc.... So I decided to tweak the per card settings. Now I'm using (lots of little experiments in here...)

Code:

cor myrig0 1080 1080 1080 1080 1110 1080 1110
mem myrig0 1980 1980 1980 1980 1850 1980 1850
pwr myrig0 2 2 2 2 2 2 2
vlt myrig0 940 940 940 940 1050 940 1050
fan myrig0 40 40 40 40 40 40 40

which is a little more stable. I get about ~22.5 on five cards and ~21.0 on two cards. Every now and then the cards shoot to 511 degrees and everything locks up (I think that is unrelated to overclocking and might be due to keeping the cards/board/PSU way too cold.) Nevertheless, this still isn't 29MH/s or even 25MH/s per card which I'm sort of expecting.

Not sure if this helps...

You should flash your cards-Bios to reach better MH/s --> 29MH/s easy with RX570
go to anorak.tech to find the right BIOS.

It's very easy with ethos to flash the Bios

minestop && disallow
Get the adaptor numbers for the cards with sudo atiflash -i
Save your current bios for backup sudo atiflash -s backupbios.rom
Flash the new bios onto the card sudo atiflash -f -p /path/to/newbios
Repeat. Do each card one by one, reboot, and check.
