I would switch back to windows and test the cards one by one till you find the best settings for each.

I have bought an existing rig from someone claiming it gives
132Mh/s with 5 GPUs 3 RX 480, 1 470 and 1 580. I faced lot of issues on
Windows, not all the GPUs were mining due to one or other issues e.g.
Driver, GPU Hanging etc. however GPUs were giving ~24-25 Mh/s. For
stability I moved to Ethos, testing my first GPU and its only giving
~4Mh/s? am I missing anything here?

Thanks in advnace for your help

Turned globalmem on 2000 and globalcore to 1200 with globalpowertune @ 5.
Having 27mhs on both 480 and 22 on the 470.
Is it ok to add globalmem and core commands with different gpus?
Rig is running at 45 degrees celcius? Seems a bit low ?
Is globalmem 2200 recommended?
Using ethos latest 2017 update. Thanks!

Hi, umm yeah still good but the motherboard is not produced anymore and you will have to go with asrock h81 pro btc r2.0

This is the particular card i am having issues with.. notice the previous owner had flash it with a rx580 bios and i tried flashing it back with rx480 bios though succeed but the version remained as rx580.

i will disable onboard graphics and try oc with claymore again.

You can set core clock to 1130 or 1150 there is no much difference.. i see no undervolt in gpu-z, 145,8w is a lot..

Does that causes unstable undervolt?

I had notice GPU1 which is the one on pcie x16 slot is never 100% load during mining is this normal? (

i had downclock all gpu cores by 50 and fans to spin 100% at 70c now, much better temps at the cost of 6mhs haha

Hi, are you running with on board video card ? If yes, try disabling it from device manager. Ill recommend to OC and undervolt from .bast file like this -cclock 1100,1150,1130,1200 -mclock 2200,2150,2100,2170 -cvddc 900 -mvddc -gser 4 -dcri 5

Hi Ciprian thanks for replying.

I had tried undervolting using claymore but seems like its not working, gpuz vddc is not fixed as it changes every reboot.

right now i am using trixx didnt really like it but at least it works. avg -70 to 100mv decrease. Will AB beta be better? Most of my core OC are 1100 and mem 2200.

Lastly i had a used rx480 nitro+ 8gb oc samsung sku #11260-01-41G which i had brought online and i am not able to find any stock bios for it. not sure what the previous owner did to it the mem straps are causing alot of gpu mem error in hwinfo and he flash the same bios on both sides of the bios 🙁

seems like most people are having 11260-01-20G. This particular 41G runs way hotter then the 20G i had and not being able to undervolt much even flashing from the same bios i took from the 20G..

Lastly i would like to thank you for your wonderful site. really informative.
