Compass Mining, a bitcoin mining firm, published a blog post stating that Bitmain, the company behind the application-specific integrated circuit mining rig, has made changes to its design. The post advised miners to be aware of the changes as Compass Mining identified “three issues” with two different Antminer S19 series mining devices.Compass Mining, a bitcoin mining company, posted atitled “Bitmain Changed Its ASIC Design.
William Foxley of Compass Mining explains that the new machines lack a peripheral interface controller on the ASICs, making it harder to control individual hashboards compared to those with a PIC. The devices use aluminum plating on the side of the mining rig, which Foxley believes may contribute to overheating issues. Additionally, there is a “consolidation of all components onto one side of the board, causing an increased chance of hashboard errors.
In conclusion, Foxley notes in the blog post that third-party firmware could address the PIC issue and enable a miner to run on one or two boards. Third-party firmware can also lower specific variables to keep the ASIC mining rig cooler. The post suggests selecting the best environmental conditions as another solution. However, regarding the aluminum plating, Compass Mining views it as a net negative.
“We view the design decision to swap to aluminum-plating on hashboards as a net negative–one that will increase ASIC failure and underhashing while increasing service and maintenance costs,” Compass’s blog post concludes. “Paired with the lack of a PIC and increased difficulty of swapping out bad chips, we encourage miners to double down on their repair game as they onboard next generation units into their fleets.
