Bitcoin mining company Compass Mining claims to have found “three issues” in the ASIC design of the two new Antminer S19 miners, units that are primarily used to mine Bitcoin (BTC).
These issues could result in the machines overheating and in some cases, completely breaking down.
The firm’s mining operations team warned in its Mar. 6 post that “Miners need to be ready,” particularly those who purchased the S19 90T and S19 XP Antminers manufactured from 2022 onwards.

While the firm stated that “other versions could be affected as well,” the three flaws the firm identified stemmed from a lack of a peripheral interface controller (PIC) on units, the implementation of aluminum plating instead of laminate material, and the bunching up components onto just one side of the board.
According to Compass Mining, peripheral interface controllers, or PICs, are used to control and monitor a range of devices and systems across all sorts of electronics. In ASICs, they’re used to interface with hashboards individually, rather than addressing them as one unit.
This, however, has been removed in the most recent design, said the firm.
“In ASICs, a PIC sits at the top of a hashboard and allows each hashboard to be spoken to individually. Without it, you have to address the unit as one unit, instead of three hashboards.”
Compass Mining explained that this lack of PIC means that should one hashboard fail, the entire unit “fails completely.”
“Instead, a miner fails completely. We’ve found this to be the case with our S19 XP 1
