With the AvalonMiner 741 we updated the number and quality of power connectors
Canaan AvalonMiner 741: The ROQSolid Miner, Refined. AvalonMiner 741 through a series of internal circuit optimization, the number of external power supply interface is adjusted to 6. This change improves the power compatibility, and enhance the user experience. Meanwhile, integrated Airforming Cooling technology, which not only can better protect the fan, but also better gather and export the heat inside to improve the efficiency of heat dissipation. More reliable, open, and even higher quality. Designed to last for the long hash.
Software Update and How to Update Your AvalonMiner & Controller
Canaan engineers have been hard at work to bring a software update to the AvalonMiner 721 and AvalonMiner Controller. As announced previously, our latest software update brings improved hashrate, improved API and bug fixes.
With the AvalonMiner 721 we upgraded the number and quality of power connectors.
The AvalonMiner 721 is ROQ Solid. In the AvalonMiner 721 we upgraded the number and quality of power connectors to increase efficiency and reliability of the AvalonMiner 721. The front face of the AvalonMiner 721 now has “8-on-front” 6-pin female power connectors so that an operator connects 8 of a power supply unit’s 6-pin male power connectors to an AvalonMiner 721. In our tests, Canaan has seen a 5-8 % increase in efficiency in our latest generation miner by moving from 4 power connectors to 8. Also, by connecting 8-on-front power connectors with quality cables, an AvalonMiner 721 should run even more consistently and reliably.
NOTE: The previous firmware works for AvalonMiner 721. The above firmware released for the AvalonMiner Controller and Raspberry Pi 1, 2, and 3 is officially starting to support AvalonMiner 721 from this current version. If there is a phenomenon where a user can update the MM firmware stating “it is not recognized,” please note that the controller firmware is normal.
As a followup to our release of the manual files, the Avalon 7 English Setup Manual is here available. This is a graphical description of how to connect up data and power connections of one or more Avalon 7 (AvalonMiner 721) units. Check out the PDF.
