Hey friends, I have some old ASIC machines from Canaan including Avalon 721 6TH. Recently, I have decided to overclock this ASIC machine and increase its hash rate from 6TH to 7TH. I’m aware of the risks involved with overclocking such as overheating and the end of warranty. But don’t worry it’s been a year after my purchase and Avalon provided 90-day warranty. In any worst case, if my device gets damaged I can get my machine repaired by paying maintenance costs.�
