Whether you are looking to venture into Bitcoin mining or are an established miner seeking efficient ASIC chip solutions, this guide offers a comprehensive look at BM1397 chips, their variants, and their suitability for the Antminer 17 Series. Read on to discover how to optimize your Bitcoin mining efforts and why D-Central should be your go-to provider for all your ASIC needs.
Understanding ASIC Miners and Hashboards
Before delving into the specifics of BM1397 chips and their application in the Antminer 17 Series, it’s crucial to have a foundational understanding of ASIC miners and hashboards.
ASIC miners are custom-built hardware specifically designed to perform a single task, and in the world of cryptocurrencies, that task is mining. Unlike CPUs or GPUs that are multi-purpose and operate across several tasks, ASIC miners are dedicated machines. Their laser-focused functionality makes them highly efficient at processing the complex mathematical problems inherent in a blockchain’s proof-of-work system, which in turn leads to effective and profitable Bitcoin mining.
Bitcoin’s SHA-256 mining algorithm, due to its complex nature, requires powerful and efficient hardware to solve its cryptographic hash functions. This is where ASIC miners have proven their worth, consistently outperforming other hardware types. Their efficiency stems from their ability to perform more hash calculations per second, which directly correlates with the likelihood of earning block rewards in the mining process. Therefore, ASIC miners have become the go-to equipment for serious Bitcoin miners, playing a dominant role in the mining landscape.
On these ASIC miners, you’ll find a key component known as a hashboard. This printed circuit board is densely populated with numerous ASIC chips and is responsible for carrying out the mining operations. Each hashboard, depending on the miner’s model, houses dozens or even hundreds of ASIC chips that collectively work to compute the hashing algorithm. As such, hashboards are essentially the ‘engine’ of the ASIC miner, driving the mining process forward.
Given their importance, the maintenance and, if necessary, replacement of ASIC chips on these hashboards becomes a critical consideration for maintaining optimal mining operations. As such, knowing the specifics of these chips, like the BM1397, is essential for anyone invested in Bitcoin mining.
Why you Need Replacement BM1397 Chips
ASIC miners, given their intensive computational tasks, generate a considerable amount of heat during operation. This isn’t just a byproduct of the mining process; it’s a tell-tale sign of the energy being expended to solve the complex mathematical problems inherent in Bitcoin mining. Heat generation in itself isn’t an issue; instead, it’s the long-term and uninterrupted operation at high temperatures that can lead to problems.
When ASIC chips run for extended periods at elevated temperatures, their lifespan and efficiency can be compromised. Overheating can lead to chip failure or damage, significantly affecting your mining performance. It’s not an uncommon scenario for miners to push their equipment to its limits, seeking to maximize output.
With the Antminer 17 Series, Bitmain, a leading ASIC miner manufacturer, attempted to address the overheating issue by opting for tin between the heatsinks and chips. This approach aimed to enhance the chip’s ability to withstand high operating temperatures, thereby improving its overall lifespan. However, this design brought along its own set of challenges.
Specifically, the temperature differential between the cooling system and the ASIC chip can cause the tin to crumble. This crumbling results in the formation of small tin balls that can become lodged in the legs of the chips, creating short circuits and potentially causing permanent damage.
The need for replacement chips arises due to these operational issues. When it comes to the BM1397 chips used in the Antminer 17 Series, there are various models and revisions, each with its unique features and capabilities. Understanding these models and knowing which one can serve as an effective replacement is crucial for maintaining your miner’s performance and longevity.

Understanding BIN and Hashboard Levels
Navigating the chip replacements, you’ll come across terms like ‘BIN numbers’ and ‘hashboard levels.’ Understanding what these terms mean can greatly influence the efficiency and longevity of your mining operations.
BIN Numbers: In the context of ASIC chips, the term BIN refers to the process of categorizing chips based on their performance. During the manufacturing process, inherent microscopic imperfections lead to variations in the power efficiency and performance of the chips. This variation allows for categorization of chips into different ‘bins.’
On your hashboard, you will find a sticker that designates the BIN number of the chips installed on that board. The idea is that you should ideally match the BIN number of the replacement chip with that of the original chip on the board. However, our testing indicates that you can match different BINs on a board without noticeable issues.
Hashboard Levels: A hashboard’s ‘level’ refers to the general stress that the hashboard can handle. In other words, it indicates the overall power and thermal load that the board and its chips can withstand without compromising performance or longevity. This concept becomes crucial when you’re configuring your miner to avoid putting too much strain on the hashboard and its chips.
If you’re recycling chips, it’s advisable to use hashboards with a similar pattern and level, designated by the sticker “L1, L2, …” on the board. Matching the chip design with the hashboard level usually yields better results. For instance, you might want to install AI, AH, or AG chips on an AG hashboard following the logic of AI > AH > AG > AF > AD.
These factors add another layer of complexity to the process of chip replacement, emphasizing the importance of expert guidance in maximizing your miner’s performance. D-Central is always available to assist in understanding these intricacies and providing a smooth path for your ASIC repairs and modifications.
Recycling Chips and Mix-Matching for Optimum Performance
In the world of ASIC mining, chip recycling and mix-matching are common practices. This process involves salvaging chips from one hashboard and utilizing them in another, often with the intent of replacing failed chips or optimizing performance. However, this practice isn’t as simple as plug-and-play; it requires careful considerations to achieve the desired results.
- Recycling Chips: Salvaging functional chips from non-operational hashboards is an economical and environmentally friendly practice. It offers an effective way to replace damaged chips, especially when certain chip models are scarce. However, care should be taken to ensure that the salvaged chips are in good condition and compatible with the target hashboard.
- Mix-Matching Chips: While chip replacement ideally involves replacing a chip with the same model, certain situations may require using a different model. For instance, when a specific model is out of stock, you might need to resort to mix-matching chips. This practice involves placing chips of different models on the same hashboard. The caveat here is that not all chip models are compatible with all hashboards.
- Compatibility: When recycling or mix-matching chips, it’s important to choose chips from a compatible or later design for optimum performance. This is where understanding the hierarchy of chip designs (AI > AH > AG > AF > AD) becomes crucial. For example, if you have an AG hashboard, you would want to install AI, AH, or AG chips. This hierarchy represents the improvement in performance and resilience with each subsequent design.
The process of recycling and mix-matching chips, while cost-effective and practical, is intricate and requires in-depth knowledge of chip designs and hashboard levels. At D-Central, our team of experts is well-versed in these nuances, offering assistance and guidance to ensure your mining operations achieve optimum performance.
