hi,

any support for R9 280, R9 290?

thanks

Still nothing ? iam managing 50+- rigs, please let me use your OS and pay you...

1. there is already a description field there for you
2. no plans for this
3. will done be soon
4. there are amd-info and nvdiai-smi commands for that

I've created a big fat example for Miningpoolhub. Check it out, that should help you. But I din't know where is lyra2z on miningpoolhub, if you know pool url and port that should be easy.

Possible.
You open your rig, under primary miner there is "Second miner" link. There you select the second miner, dstm for example.
To specify gpu used by each miner please set them in "wallet" or in "tuning" dialog in the rig. You are looking or "Claymore config override". There are tips for each miner about the config options like "-di 34ab use GPUs 3, 4, 10, 11", just click on (i) icon to see that.

Proper overclocking can be tricky with AMD cards. A lot of guys have success but still there are problems reported.
The 100% working solution is to flash your bios and with everything and do not touch that from web panel. There are upload and download bios buttons for that.
But I don't understand from your post does it consume too much watts or the hashrate is low?

300mhz means it's not mining or it can't set itself to higher performance levels.
If you say it works in windows then there is no problem with risers and so on.
- try to run it with 1 GPU, just to check if the problem still persists
- check GEN1-2 setting for PCI bus in bios, it's often reported to help setting gen1
- i'm almost sure this relates to some MB settings... don't know it's model so try to google.

If you set CoreState 2 does it change? CoreVolt seems not to have big effect on power consumption.

I think I mess around with Core State all the way from 7 to 1. The lower the Core State, the less stable the system is. I understand Linux is a different OS so what ever I do on Win10 may not work so well. I will try to down clock the core voltage in the bios and flashed it. I am not familiar with the mV hex value from 65282 to 65288?

My GPU runs well around 925-950 mV on Win10. What hex value do I set?

Lastly, I just want to say your OS is rock solid. It auto restart miner, it tracks the performance of the rig recording the error it sees, it almost NEVER crash the OS till I cant reboots it. It really good.

I believe all farm operator should use it. It is a no brainer. SMOS doesn't even come close.
