Our articles talk about Bitcoin from top to bottom. We explore all general concepts and more specific concepts related to Bitcoin mining.

What are the Antminer hardware errors

The number of hardware errors that appear on the web interface of an ASIC can sometimes seem high, but there is not necessarily a reason to worry. Indeed, it sometimes happens that the machine has been operating very well for several days. The error counter is cumulative and may seem

L3+ – L3+ hashrate is low or a hashboard is faulty

The first step to follow when your ASIC seems faulty is to do a “factory reset” of the machine. You can do this using the interface option, but it is recommended to overwrite the NAND using a MicroSD card. You can download firmware from our website download section: https://d-central.tech/downloads/firmwares/ Let

L3+ Kernel – Antminer L3+ refresh screen failure

Refresh screen glitches are repeated by posting the same message on the same page or sending the same message on different pages. When the miner’s kernel log has a refresh screen failure, how do we troubleshoot the failure? Mar 1 14:20:39 (none) local0.err cgminer[368]: Net Err! lastest job more than

S17 Kernel – Antminer S17 hashboard Chain 2 lacks chips

An Antminer S17 hashboard has 48 chips, but the kernel log finds 16 chips (as shown in the figure below); so, when we encounter this problem, how should we solve them? 2022-05-07 08:49:51 driver-btm-api.c:915:check_asic_number_with_power_on: Chain[2]: find 16 asic, times 0 2022-05-07 08:50:02 driver-btm-api.c:915:check_asic_number_with_power_on: Chain[2]: find 16 asic, times 1 2022-05-07 08:50:13

S17 Kernel – Antminer S17 Pro wrong temp sensor type

The temperature sensor chip is mainly used to sense the temperature of the hash board and its surroundings. If it is damaged, it will cause abnormal temperature readings, and the hash board will not start when the temperature is too low (the kernel log shows that the temperature sensor reading failed),

S17+ Kernel – Antminer S17+ Read temp sensor failed

According to the backstage kernel log, Antminer S17+ read the temp sensor failed, which means the temperature sensor chip is faulty. In this case, the hashboard will not start, or the miner will stop running. 2022-05-08 03:00:34 temperature.c:843:get_temp_info: read temp sensor failed: chain = 0, sensor = 2, chip =

S17+ Kernel – Antminer S17+ hashboard voltage is inconsistent

If the kernel log shows “ERROR_SOC_INIT,” it means that the Antminer S17+ hash board is mixed with inconsistent code, you can troubleshoot by following steps. 2022-03-11 08:38:21 voltage[0] = 1710 2022-03-11 08:38:21 voltage[1] = 1690 2022-03-11 08:38:21 voltage[2] = 1710 2022-03-11 08:38:21 Voltage are different.

S17+ Kernel – Antminer S17+ Chain 0 only find 0 ASIC

When Antminer S17+ kernel log shows Chain 0 only finds 0 ASIC, will cause miners to stop mining, you can troubleshoot by following steps. 2021-05-04 14:22:57 driver-btm-api.c:1162:check_asic_number_with_power_on: Chain[0]: find 0 asic, times 0 2021-05-04 14:23:06 driver-btm-api.c:1163:check_asic_number_with_power_on: Chain[0]: find 0 asic, times 1 2021-05-04 14:23:17 driver-btm-api.c:1164:check_asic_number_with_power_on: Chain[0]: find 0 asic, times
