The story so far:
• People with A10 4GB miners will need to get a $1200 memory upgrade (from 4GB up to 6GB) from Inno if they want to continue mining ETH
• There is a small number of people who have the A10 non-Pro that has 5GB of memory. These do not appear to have any new firmware available.
• People with A10 Pro 5GB miners will most likely need to upgrade their firmware, Inno is trying to release a stable version. There are numerous reports of dropping hashrate and very poor accept/rejected shares. We’ve all be testing various versions of the firmware with little luck in the long term, some luck in the short term. I’m personally going to try upgrading my A10 Pro 5GB (A10L) to 6GB, which would only cost me $600 since it’s only a 1GB upgrade, so we’ll see how that goes once the parts come in a few weeks from now.
• People with A10 Pro 6GB (A10U) miners should not be having issues, but some people say they are. Some people have upgraded to the Oct 26 A10U firmware and have reported better performance.
Various A10 Model Numbers and Firmware:
A10 with 4GB - no new firmware available
A10 with 5GB - no new firmware available
A10L with 5GB - Oct 26 firmware available, seemingly good results for some people, but not for others
A10U with 6GB - Oct 26 firmware available, seemingly good results
