We will try to source a gfx804 based RX550 to see what is going on.
I'll be glad to help. Let me know if you need more logs, test new build or something else.
We have ordered three different RX550 from different makes, hopefully at least one will be with gfx804

One last thing, if you are testing with
-clgreen 1, hashrate may be lower (in this case significantly lower apparently), so please try without -clgreen 1 and see if it makes a difference.
The config seems OK apart from the two -mport options but the second one just overrides the value of the first one, so this isn't really a problem. As for the missing temperature and fan data - this is quite strange, we haven't seen this - perhaps this depends on how hiveOS extracts these: from the miner, or independently. It seems that hiveOS 0.5-74 is based on Ubuntu 18.04, which may be cause or at least part of the problem - we are testing now with Ubuntu 18.04 LTS, so we hope that we will find and fix any problems.
As for the -tt not working - this is normal, as we do not support hardware control under Linux yet. It will be added in the next version.
I think it's because there is a
-tt 0 in there...
You are absolutely right!

After the initial implementation, we haven't used
-tt 0 at all, but it will definitely turn off the hardware monitoring.
Can you add MOAC and CLO coins please? Thanks.
CLO is added already (since 3.0c), you just need to specify
-coin clo and it will mine the devfee in CLO. As for MOAC - it will be added in 3.5d, which will be released later today or tomorrow morning.
Good Job, developers, such a nice miner.
I'm linux user and on the way to migrate my machines on Phoenix, but some bugs don't allow me.
The fan management is just bad. The temperature is good got, but fans doesn't move their first percentage and this could take the cards to hell.
Probably know, but the fans for AMD are managed from (AMDGPU PRO):
/sys/class/drm/card*/device/hwmon/hwmon*/pwm1 (from 0 to 255)
PS: If there is internal GPU - this will confuse the next cards - they'll be +1.
But only root can change this, so
This cron work for me on Ubuntu (I think this is not working on Debian):
@reboot chown [miner_username]: /sys/class/drm/card*/device/hwmon/hwmon*/pwm1
Hope it helps for better fan management.
It's possible to write a custom script, but don't think is the right way to manage the fans.
Thank you for trying our miner! Unfortunately, the cyrrent Linux version, there is
no support for controlling the fans, voltages, etc. It definitely
will be added in the next version but for 3.5 you have to use external software to control the clocks and voltages. We will also finally add Nvidia hardware control for both Windows and Linux in the next version (3.6).
I tested all drivers, same situation, i report this problem before and you say this(down). This screenshot

Sorry about these problems. Unfortunately, there is no easy way to fix this as with our cards the settings work more or less OK. In the next release (3.6), we will add more ways to control the temperatures, voltages and fan speeds, which will hopefully work better for your cards than the current method via the AMD-approved ADL library API.
