Tha latest version run perfectly under Linux with 2 RX580 8Gb
Is there any plan to add dual mining support?

Hello,
What are your settings for the RX580 8G? Core Speed/Mem Speed/Voltage? What do you have your -h set at? Are you running SMOS?
I'm wondering if you are able to get it stable for longer than 24hrs. I can usually get my RX580 8G rigs stable for 5-8 hrs but then it will reset so I end up getting 3-4 resets in a day. When I was mining ETH with the same rig, it would be stable for 24hr+. Right now my settings are 1200/2000/1000mV with a -h of 1600 running SMOS. I am also running RX570 4G rigs and they are a little more stable at 1-2 resets a day. Not sure why the higher memory cards are having issues. Settings for the 4G cards are 1200/1750/1000mV with a -h of 850 running SMOS.
Both of my rigs are using 11 GPUs, 8G of RAM, z270 chipset.
Cheers,
I would hazard a guess that your memory is too far OC'ed. Cards that were stable on ETH for me, have been less tolerant under Cryptonote or Equihash - maybe because both of those are much more memory hard. To be honest, this exact reason is why I stopped using Nicehash Miner and just configure the software to point to their servers as I found when it switches settings, one set of OC/voltage/config for cards that worked in ETH might crash them when it flips to another algo.
I had the same issue and I think I discovered why - Cryptonight uses all of the GPUs memory while ETH only uses ~2.3GB. This means the memory needs more power on cryptonight.
Long story short: increase the power limit on the GPUs. I had mine at 0 for ETH but +5-10 makes my cards stable for Cryptonight.
Interesting, I didn't know that ETH only uses 2.3Gb of memory.
As for the OC'd cards, 2000mHz is actually stock speed so unless I need to underclock to solve this issue.
When you've increased the power limit, is that the memory voltage or just the overall power level? In SMOS I have two options which is why I'm asking. Do you know what voltage level you were running the cards? I'm at 1000mV right now, which is undervolted I believe. I'm not sure what stock voltage levels are (maybe 1300 or 1400?)
Thanks!
2.3GB is the current size of the DAG file (epoch 150 I think). Cryptonote definitely uses more (it tells you on initialisation exactly how much) and hammers the memory controller a lot more, it's a lot less tolerant of overclocking too. 1050-1100mV seems to be 'normal' voltage for the R9 and RX cards when in 3D mode.
