in my opinion using global commands not usefull. i only set globalfanspeed and maxgputemp for all rigs
maxgputemp 75
globalfan 80
settings fine for all my rigs.
all of other settings as core mem clock settings optimised rig by rig
I don't have the time to optimize all cards individual. So I choose for stable settings that will work on every card with Samsung memory.
But my problem has nothing to do with the global commands. I think it has something to do with nvidia-smi but didn't found the solution yet.
I'm thinking of switching back to nvOC because that gives me a better hashrate and lower power usage

But now I just bought ethOS and I like the panel they use. So maybe it will be better to continue using ethOS and hopefully I will found a solution to get the same results as nvOC.
