If you decide to increase your income in mining, then buying additional equipment is the best option. But there is not always money for it. Places for installation may also not be enough. Then only ASIC firmware remains. I installed this one for my ASIC: https://ultramining.com/en/firmwares/bitmain/antminer-l3/
as an option. In general, Ultramining has a lot of firmware from Bitmain that you can download, so come and have a look!
