Compass Mining has announced design changes ASIC hash boards Bitmain S19
The move is part of the company's efforts to improve the user experience and optimize the mining process.
Compass Mining has notified the community of issues with the new Antminer S19 series rigs from the manufacturer Bitmain intended for cryptocurrency mining. In the official blog of Compass Mining, it was stated that Bitmain made changes to the design ASIC Bitmain S19, which has a critical impact on the performance of new devices. Compass Mining considers change on its back ASIC from laminated boards to aluminum coating as very negative. This can lead to a significant increase in breakdowns and maintenance costs. Without PIC inspection and more complexity in replacing faulty chips, Compass Mining urges miners to prepare for possible repairs.
William Foxley, a representative of Compass Mining, explained that the new devices do not have a Peripheral Interface Controller (PIC) on ASIC, which complicates the management of individual hashrate panels compared to those that PICs have. A device without a PIC will not be able to continue mining on one or two boards. Foxley said that in the past, laminated multi-layer plates with tracks built into layers of laminated material were used in almost all mining equipment. On one side of the board the chips (signal side) were connected by tracks and on the other side the cooler (power side). However, new devices Bitmainu have single-sided plates with an aluminum base. According to Foxley, the aluminum coating could lead to overheating problems. Hashrate aluminum coated boards will have significantly higher failure rates at higher device and ambient temperatures than those built on printed circuit boards (PCBs). In addition, the use of aluminum-coated hashrate boards can lead to increased maintenance time and costs, as the probability of errors in the use of wires, chips or other components increases, and repairs ASIC they can be more complex. William Foxley claims that the unnecessary merging of all components on one side of the board increases the risk of errors in the hashrate work of the board.
