Hint for enable correct undervolting in smos:
Use ssh client to access farm.
Login as miner/miner.
sudo su
mc -c
Find and edit string #95 in /root/utils/oc_dmp2.sh - remove REM symbol (#) before "--memstate" and add "--vddci 900" before "--mvdd 950"
Use your own voltages if presented not adequate for your card (i use --vddci 850 --mvdd 900 for Sapphire rx588 SE with custom bios).
reboot
What about SMOS automatic updates if I do any change in this file? Will SMOS overwrite my changes? Is it possible to disable automatic updates to prevent oc_dmp2.sh file overwriting?
