Antminer
MOSFET issue In the world of crypto mining, uptime is everything. Every minute a machine is offline is money left on the table. Previously, I discussed common MOSFET issues specifically affecting the Antminer S19J Pro. Today, we are broadening that scope to look at a quick—albeit temporary—fix for older generation units, like the standard S19 … Read more
Antminer S19K Pro The Bitmain Antminer S19K Pro is a workhorse in the current mining landscape, but like any piece of high-performance hardware running 24/7, it develops characteristic faults. One of the most common headaches technicians face with the S19K Pro hashboard is power irregularity. When a hashboard domain isn’t receiving the correct voltage, it … Read more
Antminer S19J Pro: Fixing the Common MOSFET Issue, Bitmain Antminer S19J Pro repairing
Bitmain Antminer S19K Pro The cryptocurrency mining hardware market is constantly evolving, and keeping up with the hardware architecture of new models is essential for any repair technician. Recently, the Bitmain Antminer S19K Pro has become a popular choice for miners. With a current market price hovering around $720 and a hash rate of 120 … Read more
Got a fan error on your Antminer S19K Pro? Good news: this is often one of the easier DIY repairs, and you likely won’t need to send it to a repair shop. If you’re certain it’s a fan issue, you can save time and money by handling it yourself. However, a fan error on the … Read more
EEPROM Error When running Bitmain Antminer S19, you may sometimes see an EEPROM error, especially after swapping a hashboard from another miner. At crypto miner repair centers, it’s common to consolidate machines by exchanging hashboards, and that’s when EEPROM issues often appear. As mentioned in a previous article, one way to fix an Antminer EEPROM … Read more
Bitmain Antminer S21 The Bitmain Antminer S21 delivers a higher hashrate compared to many other models, making it a powerful option for mining. Like all miners, however, it can face issues when certain chips or components fail. The good news is that if only a few chips are bad, the Antminer S21 can often be … Read more
When it comes to repairing the Antminer S19XP hashboard, understanding the S19XP voltage flow is absolutely essential. Bitmain Antminer hashboard designs vary greatly between models, and the Antminer S19XP is no exception. Unlike Whatsminer models—which follow a relatively consistent voltage structure across versions like M30 and M50—the S19XP voltage flow is unique and requires specific … Read more
When inspecting an Antminer S19XP hashboard, understanding the voltage flow of its five key signals is critical: RST, RX, BI (BO), CLK, and TX. Each of these signals has a specific voltage range as it passes through the ASIC chips, and a failure in any one of them can prevent the entire hashboard from working. … Read more
Antminer S19XP {ERR:H1} error With the rise of more efficient crypto miners, it’s easy to overlook older models. However, some like the Antminer S19XP are still going strong with nearly 140 TH/s of hashing power. Despite its reliability, a common issue with this unit is the XP bad ASIC chip (BM1366AL , BM1366AG)error. This article walks through a real example of … Read more
