i read this but no understud
--eth_hashwatch(=M,M) Defines a min/max watchdog hashrate in MH/s expected when gpus are hashing. If a GPU falls outside
of this range for too long it will be considered faulty and the watchdog will be triggered. The
default min/max values are 2 MH/s and 150 MH/s. To activate with default values, use
--eth_hashwatch. To set your own values, use e.g.
--eth_hashwatch=1.25,60. The same range is used
for all gpus in the rig. A negative value for one side disables it, e.g. use --eth_hashwatch=-1,1000
to handle gpu resets that result in huge fake hashrates but no minimum check.
what is what in this? --eth_hashwatch=1.25,60

1 is gPU1 ?
25 is minimum 25mh ?
60 is maximum 60mh?
or 1.25 is MH min?
i have 6 vega and 1 vega give 45-50mh/s - all rig have 280mh
this option use only1 gpu HR or all rig HR ? what command i must use?
or
this option use for 1,vega- and i use only default command --eth_hashwatch??
i wont restart miner if my rig give 200mh or less. pls what comand i use for this?
this command --eth_hashwatch=200,300 is good? 200hr min 300 max? why i must use MAX?
or i must use for 1 gpu limit?
this command --eth_hashwatch=40,51
every gpu follows this range in your mining config.
if any GPU falls under 1.25 MHs it would trigger watchdog. If it goes beyond 60 MHs it would trigger the watchdog. Ethash is in MHs for almost every card hence the MHs is unit of measurement.
You can use anything below 40 for min and anything above 60 or a more flexible range like 35 as min,70 as max.
