This change has raised some concerns and questions among miners.

The lack of a PIC in the Antminer S19j Pro+ could have implications for the machine’s performance and servicing needs. Without a PIC, the machine rely on alternative methods for managing communication between components, which could potentially lead to reduced efficiency or increased complexity in addressing issues that may arise. Additionally, servicing and troubleshooting the mining machine might become more challenging for technicians, as they need to adapt to a different system architecture without a dedicated PIC to manage the device’s operations.

However, it is important to note that Bitmain may have implemented alternative solutions to address these concerns, ensuring that the Antminer S19j Pro+ remains a competitive and reliable mining machine despite the absence of a PIC. Further information from Bitmain or user experiences could provide better insights into the potential impact of this production change on the machine’s overall performance and maintenance requirements.

Investigating the Reasons Behind Production Changes

By learning from past failures, Bitmain may have improved the manufacturing process for the S19j Pro+, ensuring that the heatsinks are properly soldered and that the machine runs cooler than previous models. This could enhance the overall performance, efficiency, and reliability of the mining machine.

There may be other reasons for the production changes in the Antminer S19j Pro+ that are not yet publicly disclosed or well understood. Bitmain may have had specific design goals or faced constraints that led them to make these changes. Without official confirmation or detailed explanations from the company, it is difficult to determine the exact rationale behind these modifications.

The scope and potential repercussions of the production changes in the Antminer S19j Pro+ are still not entirely clear. Some changes, such as the heatsink design, could have a direct impact on the machine’s performance, efficiency, and reliability.
