GPUs stop mining in Linux

[N1kon]

After constantly fighting with windows for months. I decided to make the leap to Linux for my mining rig thinking it would be more reliable. Well.... not really.



When I start mining, everything is fine. Temps never get above 73 on hottest card during mid-day. It appears that after about 30+ mins or so GPUs start disappearing from the miner terminal window and stop hashing (they still show in Nvidia x-server). Some GPUs can take 10+hours to disappear. After about 24 hours of mining, only 4 are still working (confirmed with pool). Only way to get them back is to reboot the rig. I have tried changing risers and I still have this issue. Any ideas?




Currently I am running,

 Ubuntu 16.04
B250 Mining Expert MOBO
DSTM mining ZelCash
7 GPUs
1x Gigabyte G1 GTX1070
2x Gigabyte Mini GTX1070
1x Asus Strix GTX1070
2x Zotac Mini GTX1070ti
1x Gigabyte GTX1080


All card undervolted to 150W or less. No OC no anything.

Power:
1200w PSU ---> 3x GPU + MOBO + HDD, etc.    ~~500W used
1200w Server PSU ---> 4x GPU                         ~~600W used

Try NvOC, i think is better and more easy to solve your problem.

ETN mining can also be via computer CPU. if you've tried mining with applications provided Electroneum for windows. but can not also mine with Terminal Linux.

Look at the system log for errors. (cat /var/log/syslog) or (dmesg)
In similar situation i saw that motherboard disconnect the cards/PCIe slots; the solution: change the motherboard; also stop mining with the CPU and use only GPUs.
