What is the issue of the miner? According to the images above all miners are running but the two miner shows only 2 hashboards and the other one shows 3 hashboards but the 3rd hashboard only have 51 ASIC chips so the 12 ASIC chips might be dead. Let me ask if these two miners with 2 hashboards only have 2 hashboards each? or they have 3 hashboard but the 1 hashboard not showing on the miners status? Better explain here what exactly the problem of the miner Because you are still getting hashboard on these miners but with lower hashrate.

Not really, this means most likely Chip number 52 is dead , but regardless, this board is as good as dead, depending on the firmware , but I would say most firmware versions by bitmain don't do well with boards that report anything below 63 chips on a single board. The 3 images he posted look pretty normal, 2 miners with 2 hash boards, 1 miner with 2 good hash boards and 1 bad hash board, the problem is the part that says the same day What are the chances of 3 boards on 3 different miners , get toasted on the same exact day? op did you have any power issues? any chances the voltage has dropped? can you try different PSUs to confirm it's not a power issue? also please post the kernel log for each, use the code format when you post the Kernel log example : Code: i2c /dev entries driver Title: Re: 3 of my miners failed the same day Post by: Steamtyme on September 16, 2019, 06:09:08 PM You might get a decent diagnosis here, but don't waste any time, get your RMA started with Bitmain if that's still an option. It will only drag out if you wait before getting it started. How long were they running before the failure? Sometimes cables come loose in transport so if something isn't seated right it could be reading as dead. I've had minimal exposure to Bitmain gear, but in the past I would lose a chain and not the entire board if there was suspect chip.
