I found the problem. Changed BIOS settings from "GEN1" to "AUTO"

Is your monitor plugged into GPU0?

Have you modded your bios of GPU0 the same as the other cards?

Can you try another MoBo?

I am running 40 cards total on this version and modded all cards with timings, undervolt and clock speeds and I don't have that issue at all.

All my AMD rigs GPU0 performs the same as other GPU's that are alike.

Why does GPU0 have much less performance than others?
I tried from 2 to 6 cards 470 and 580
On the cards nVidia there is no such thing, everyone works the same performance.

Thank you ! You gave me a real envy to test your distro with your answer! I hope it will help me, and if I succeed... will pm you to ask your address as a thank you.

thanks again ! and I wish you a lot of success with your software!

edit: would be nice to have a torrent link to download it

It seems like no one has succeeded with that because no one posted a success story
I am ok to use Polaris BIOS Editor, or do manual hex patching. No matter what I was not able to fix the issue with high power consumption under linux with rx470 and asked for anyone who WAS able to do that to share how.

I think I've found the problem, it is not solved by updating:
I installed xubuntu in a new pendrive. And did a apt dist-upgrade, after that, I rebooted and installed lastest amdgpu-pro drivers, and then it happended exactly the same.
I am able to press ctrl+f1 and work via command prompt, but it is not solved by updating.
I am still trying to connect the pendrive to the 2.0 USB port, but it is not recognized. Why do you suggest to do it like this?

Thanks for your help!

What GPUs are you using?

4 Asus Dual RX 580 8GB

Actually, I tried to remove all nvidia-smi commands at all and reboot. Still higher power consumption with modded BIOS comparing to Windows.
That is why I asked anyone who was able to run rx470 undervolted on Linux: please post your PBE screenshots and linux settings.

So I believe I am having the same problem (except my cards are stock), my hash rate doesn't change no matter what settings I use, I even tried your suggestion here leaving overdrive and performance level blank and I was still getting the same hash...

 If you want to do a build using the AMD 15.12 drivers (which are the best for the R-series cards but don't support the Fury or anything later), you will have to move to Ubuntu 14.04 (or earlier but I don't recommend earlier) for the base build - and even THERE you can't "upgrade" everything as the newer XOrg version that "apt-update" inflicts on 14.04 DOES NOT WORK WITH THE fglrx DRIVERS.


 AMD got particularly stupid when they decided to ignore older cards in their LINUX "pro" driver series, though they've had a long history of not supporting LINUX all that well.
 A lot of folks count 15.12 as an amazingly good but one-time exception.

I tried with a new motherboard MSI Z270 Gaming Plus with only one GPU directly connected to it,  and a new PSU.
Same Result.
I have extra pendrives but I am not able to copy the image there because they are 15.5 Gb and I it needs 15.6.

It isn't yet available

is it possible to set overclock individually and set the max TDP with watts like nvOC?

How did you get linux to oc rx cards? would you mind sharing it?

Didn't you think about putting oneBash to GitHub? Makes it much easier for custom modifications.

For instance, I would group similar options for cards (mostly for nvOC version) into loops using bash (you can pull changes if like it). Another option for me may be to split oneBash into few option files like 10-power.sh, 20-miners.sh, etc... Next step would be to add a kind of rig autodetect (say, using NIC MAC) and load rig-dependant options automatically, still having single settings repository.

Will do it for myself, but integration of user changes will be much easier using git.

You've missed the point. I have modified BIOS using PBE, but it seems that drivers ignore flashed settings and use some driver defaults for voltages.

I guess I do something wrong. Anybody who is running rx470 under linux with low voltages, can you show your PBE values and corresponding rxOC settings (powerplay, etc)?

I've added myself on both nvoc and rxoc but can you add ubiq to further versions of onebash? TY

I use amdmeminfo alot during my initial farm setup -- saves me a lot of trouble going back and forth Windows and GPUZ.

I can identify GPU details, memory, etc and flash them all in Linux (Polaris-BIOS editing in Windows though)

The utility also list each card according to slot ID so its cool.

check into atiflash i couldnt use it in while it was in it current folder
had to install it into another fold.. /usr/local/bin is where i put it

After trying nvOC I decided to try rxOC. It works, but I have few questions.

My test rx470 rig has modified BIOS with low voltage levels (around 950mV for GPU, for instance). Under Windows I used WattTool to alter clocks and voltages as well. But if I didn't run WattTool, I had BIOS-defined low voltages and clocks.

Now under rxOC I set GPU clock to 6 (of 7 max). It runs but I have 200 more watts for 6 GPUs comparing to Windows system. Using rocm-smi, I realised that GPU still runs at level 7. After explicit command to set it to lower levels (say, 5 or 6), I can see it set for few seconds, and then it immediately reset to level 7. I read that change is active until another OpenCL program is started. So I tried to change it before Claymore's miner, and after it started - nothing helped.

In addition, since power usage is much more than under Windows, I guess that drivers ignore BIOS voltage levels and set them explicitly to some defaults (at least, I read about that on Windows some day).

So in short, all rx470 run and maximum clocks and use some high voltages and not those written in the BIOS.

Any suggestions? I wish I can have the same power and performance as on Windows system. Hash rate is a bit lower comparing to Windows one (around 0.5-0.7 MH/s per card), and it might be the difference between Linux and Windows miner timers (it always was for fglrx as well). But what about voltages? Please advise!
