What You Need To Know About the T17+ Mining Hardware

The T17+ mining hardware is a powerful and reliable ASIC (application-specific integrated circuit) for mining cryptocurrencies such as Bitcoin. It features the latest BM1397 chip with four chips per group, 11 voltage domains, and a 25M crystal oscillator clock. To make sure your T17+ runs smoothly you should be aware of the working voltages of each component as well as key circuits like CLK (XIN), TX (CI/CO), RX (RI/RO), BO (BI/BO) signals direction; LDO 1.8V or PLL 0.8V abnormal situation; core voltage abnormality etc., which could lead to malfunctions or poor performance in your miner if not properly taken care of.

Principle Description of T17+ Hash Board Signal Direction

The T17+ hash board signal direction is an important factor in ensuring the miner’s performance and stability. The CLK (XIN) signal direction runs from chip 01 to chip 44, and its voltage during operation is 1.6-1.8V. The TX (CI/CO) signal direction runs from chip 44 to chip 01, with a 0V voltage when the IO line is not inserted, and the voltage during operation is 1.8V. The RX (RI/RO) signal direction also runs from chip 44 to chip 01 but returns to pin 8 of the signal cable terminal via U1 and return to the control board; its voltage is 0.3V when the IO line is not inserted, and 1.8V during operation. BO (BI/BO) signals run from chip 01 to chip 44 with a 0V measurement value when measuring with a multimeter, while RST signals run input from pin 3 of the IO port before being transmitted from chip 01 to chip 44; its voltage is 0V without IO signal or in standby mode and 1.8V in operation. Furthermore, power supply monitoring circuits are connected between chips 44-01, chips 00-45, chips 46-03, chips 04-47 and chips 48-05 which help regulate their respective working voltages as well as providing overheat protection for these components should they exceed their operational limits. Additionally, there are current limiting resistors connected between all four groups of pins on each side of the ICs that helps prevent excessive current draw that could lead to severe damage on your hardware if left unchecked for too long.

Step-by-Step Guide to Troubleshooting and Repairing Antminer T17+

1. Perform visual inspection on the hash board to be repaired, observe whether the PCB is deformed or burnt.

2. Test the impedance of each voltage domain to detect whether there is a short circuit or an open circuit.

3. Check whether the voltage of each domain is about 1.6 V

4. Use test fixture to perform chip detection and determine positioning based on test results

5. Test voltages of chip test points (CO / NRST / RO / XIN / BI), VDD0V8, and VDD1V8 starting from vicinity of faulty chip

6 Re-solder chips if necessary by adding flux around it and heating solder joints until dissolved state is achieved

7 Perform fixture tests twice; once after replacement accessories are complete, then again when hash board has cooled down completely

8 Prepare relevant maintenance/ analysis records for feedback to production, after-sales, research & development departments

9 Install entire miner for conventional aging.

10 Check if all miner components are functioning correctly and conduct final tests with an electrical load.

Common Malfunctions and Poor Performance Issues With T17+ Miners

When it comes to mining hardware, the T17+ miner is one of the best on the market. However, like any piece of technology, there may be common malfunctions and poor performance issues that miners should be aware of. The most typical malfunctions include LDO 1.8V or PLL 0.8V being abnormal, core voltage abnormalities, and short circuits in MOSs corresponding to a group. Poor performance issues can arise from incomplete chip readings due to low voltages or few chips appearing because of PIC soldering errors or programming problems. To ensure your miner runs as smoothly as possible, it’s important to understand these potential pitfalls and take steps to prevent them before they occur.

Common malfunctions and poor performance with hash boards can include low voltage, reset signal issues, chip signal pin output problems, temperature reading abnormalities, and insufficient nonce return. Low voltage is a common issue for ASIC miners; when no operation is performed, the voltage should be 0V and during operation it should be 1.8V. Reset signal issues can occur when the test button of the fixture is pressed, resulting in an output signal again, and when status or voltage of the test points are abnormal. Chip signal pin output problems can be further determined by measuring impedance to ground after power has been turned off. Temperature reading abnormalities can occur when the temperature sensor model or welding of surrounding parts is faulty, while insufficient nonce return may result from chips that have not been soldered correctly or need to be replaced due to bad soldering around them. To maintain hash boards effectively, users should inspect PIC soldering and programming

Tips for Maintaining Your ASIC Mining Equipment

Maintaining your ASIC mining equipment is essential for optimal performance, so it’s important to be aware of the proper techniques. The most important steps for successful maintenance include regularly checking the voltages of all test points, verifying no short circuits exist in the MOSs associated with a group, and ensuring that the PIC soldering and programming are up-to-date. Additionally, it may be beneficial to use an escrow service to ensure secure transactions when buying or selling any mining hardware.


Maintaining ASIC mining hardware is essential for successful operations and can help miners ensure that they are getting the most out of their equipment. By regularly checking voltages, verifying no short circuits exist in MOSs associated with a group, and confirming PIC soldering and programming are up-to-date, miners can maximize efficiency while avoiding common malfunctions or poor performance issues. Additionally, using an escrow service when buying or selling any mining hardware provides extra security to guarantee secure transactions. With these tips in mind, you’ll be better equipped to maintain your ASIC miner so it runs at peak performance.
