Yes those screen shots look pretty horrid with the miners restarting every few minutes. One thing that can cause it is low line voltage as the 1047 PSU does not like a low line when trying to run at full speed.
Do they work better in "Normal" mode vs High Performance? Normal mode should put them around 30-31THs.
What in your AC line at? It must never go below 205VAC and preferred range is 220-240VAC,
Considering globalstar's links point to them being in Iran I have to assume that they bought through a reseller and not one of
Canaan's authorized distributors because Canaan has none that service Iran. The only authorized distributor that *might* ship to Iran would be
Cryptouniverse who are located in Russia.
If that is the case then it is the reseller they bought the miners from that they should name here and go after to get the miners fixed. Canaan cannot control what unauthorized and/or unscrupulous resellers do. All Avalons I have ever gotten (through Blokforge in USA) arrived in pristine condition.
I've been mining since 2014 and quit running Antminers in late 2016 because of reliability issues: the s1 through s7 were great but starting with the s9's I averaged 20% failures (dying hash boards) after just 1 year. After that I began running over 2 dozen Avalons ranging from the 7xx series to the current 10xx series and have never had even 1 major failure with them. Lost a couple fans after they have been running for about 2 years but that is the only problem I have had with them.
