The mining machine manufacturer Innosilicon issued an announcement stating that as the Ethash algorithm continues to scale, it is expected that machines with 4G memory will not be able to run in the near future. Considering that there are still a few A10 (4G) users, they will arrange for the upgrade from A10 (4G) to A10 Pro (6G) soon, and carry out comprehensive maintenance of machines. With immediate effect, Innosilicon has officially accepted A10 (4G) scale-upgrade applications. Since the upgrade requires chip reservation and scheduling in advance, users shall submit reservation request forms before September 27 (including the day).
