Sometimes I was asked how to choose used #whatsminer mining rigs. Here I listed FOUR points FYI 👀
1️⃣Aging test twice because restart once is required. When the machine runs to the standard hashrate, run another half an hour and then restart to see if everything is ok.

2️⃣Check the previous miner log to see if there was an error code of hashrate board or power failure. If there is no miner log, then it is better to know the reason.
3️⃣ It is better to confirm the hashrate by testing rather than see the SN label only. Besides, check the label info of the hashboard via #whatsminer tool. Remember that the PCB info of the three boards is different but the BIN info of the three boards is the same.
4️⃣ Check the appearance of the hash board, burned board is not acceptable even it has been repaired, because long time stable running may not be guaranteed.
