We have partnered with the leading aftermarket overclock FW developer Vnish team to help our customers achieve ROI faster.

If you'd like to get the most out of your ASIC, we recommend using our FW version*.

ATTENTION: As of March, 2024 Bitmain closed (for now) the ability to use any king of 3rd party firmware in new stock firmware. If you have a new miner not compatible with Vnish, please roll back to one of the previous versions you can find here:

Install with Vnish/Alpha Miner Toolkit. It makes install easy and allows quick install on multiple machines.
