Bitcoin mining firm Compass Mining claims to have discovered “three points” within the ASIC design of the 2 new Antminer S19 miners, models which are primarily used to mine Bitcoin (BTC).
These points might outcome within the machines overheating and, in some circumstances, utterly breaking down.
The agency’s mining operations group warned in its March 6 put up that “Miners should be prepared,” significantly those that bought the S19 90T and S19 XP Antminers manufactured from 2022 onwards.

Whereas the agency acknowledged that “different variations may very well be affected as properly,” the three flaws the agency recognized stemmed from an absence of a peripheral interface controller (PIC) on models, the implementation of aluminum plating as an alternative of laminate materials, and the bunching up elements onto only one aspect of the board.
In accordance with Compass Mining, peripheral interface controllers, or PICs, are used to manage and monitor a spread of gadgets and methods throughout all kinds of electronics. In ASICs, they’re used to interface with hashboards individually, quite than addressing them as one unit.
This, nevertheless, has been eliminated in the latest design, stated the agency.
“In ASICs, a PIC sits on the high of a hashboard and permits every hashboard to be spoken to individually. With out it, it’s a must to handle the unit as one unit, as an alternative of three hashboards.”
Compass Mining defined that this lack of PIC signifies that ought to one hashboard fail, all the unit “fails utterly.”
“As an alternative, a miner fails utterly. We’ve discovered this to be the case with our S19 XP 141 TH models, which have failed utterly when just one board is having points.”
The mining firm additionally stated that by implementing aluminum plating on the hashboard, it could overheat and due to this fact result in the next “failure price” than these constructed on printed circuit boards (PCBs) — which is what the previous S19s have been constructed on.
This is able to result in “increased servicing wants,” the corporate stated.
In the meantime, the corporate has additionally raised considerations concerning the mining unit’s transition to aluminum, referring to it as “web adverse.”
“We view the design choice to swap to aluminum-plating on hashboards as a web adverse — one that can improve ASIC failure and underhashing whereas growing service and upkeep prices,” it wrote.
The agency additionally defined that the presence of the aluminum would make it tougher to interchange malfunctioning chips:
“The shortage of a PIC is compounded by the abrupt change to aluminum-plates on all hashboards. If a board overheats due to the aluminum’s warmth dispersion properties, then all the unit will go down as an alternative of only one board.”
Compass Mining stated they first realized the drop in efficiency after they deployed the S19 XP at its Texas companion facility — which might have been impacted by humidity and warmth.
As for the third problem, the agency famous that by implementing the aluminium plating with out altering the chassis — the bottom body of the ASIC — would additionally contribute to the upper failure charges.
As a result of aluminium could be very warmth emissive, the metallic will trigger “convective heating” contained in the chassis, the agency defined, earlier than proposing some options:
“An answer to this in an air-cooled surroundings could be to extend the mass air circulate sufficiently to dissipate the warmth saved inside the miner – a distinct design or stronger followers.”

Different potential options proposed by the agency embody discovering third-party firmware that enables the frequency and voltage of the machine to keep up affordable temperature and humidity ranges to be able to get extra longevity out of the mining machines.
The agency did nevertheless acknowledge that they might have simply gotten a “unhealthy batch” from Bitmain, noting it’s “frequent data” in Bitcoin mining to not purchase the primary batch of Bitcoin ASICs.
“Unknown errors are sometimes solely revealed over time, so it’s greatest to have others discover them out first,” it stated.
Cointelegraph reached out to Bitmain for remark however didn’t obtain a response by the point of publication.
Bitmain Antminers have been used to mine proof-of-work cryptocurrencies akin to BTC, Dogecoin (DOGE) and Litecoin (LTC).
