ASIC Miner ICERIVER KAS KS0 Profitability

ASIC Miner ICERIVER KAS KS0 Profitability In the realm of cryptocurrency mining, the Iceriver KAS KS0 miner has garnered widespread attention. Tailored specifically for the Kaspa network's KHeavyHash algorithm, it boasts high hashing power and low power consumption, making it an ideal choice for many miners. In this article, we will comprehensively assess IceRiver KS0 profitability while considering the Kaspa market conditions and the attributes of KS0 miner. Kaspa Market Dynamics Kaspa is a vibrant cryptocurrency network aimed at delivering high performance and scalability for everyday transactions. At the time of writing this article, the Kaspa coin trades at approximately $0.04959. But it's essential to note that cryptocurrency markets are highly susceptible to price volatility. Hence, investors must remain vigilant about market dynamics. Additionally, the Kaspa network's mining difficulty and reward mechanisms play a role in mining returns. Attributes of the IceRiver KS

Antminer S17 kernel log common faults and solutions

Antminer S17 kernel log common faults and solutions

The following faults are from the backstage kernel log of Antminer S17. Other models of Antminer are for reference only.

Fault 1: The number of chips is incomplete, only some chips are detected

find 16 asic
Only 16 chips are detected from the kernel log, but a single S17 hash board has 48 chips, so the chip count is insufficient.
Solution:
Use the fluke 15B+ multimeter to check whether the voltage and resistance of the 5 signal points of the No.16 and No.17 chips are normal and compare them with the resistance of the normal chip to determine the faulty chip.

Fault 2: The power supply voltage is unstable

The unstable power supply voltage will cause the miner's hash board to shut down automatically, and the hash rate calculation cannot be performed, thus causing the miner to be unable to mine normally.
voltage instability prompt
Solution:
a: First, visually check whether the miner's power cord is loose; it is recommended to re-plug or replace a new power cord.
b: Use the fluke 15B+ multimeter to check whether the miner's power supply voltage has reached the standard voltage for the normal operation of the miner. If it does not reach the standard voltage, replacing the Antminer S17 power supply with the new APW9 power supply is recommended.

c: Check whether the miner is grounded correctly; if the miner is not grounded correctly, the miner's voltage will also be unstable.

Please refer to the article for miner grounding detection: Check if your miner is properly grounded.

Fault 3: Chip count is 0, no chip detected

find 0 asic
Solution:
1. Swap the data cable that shows "find 0 asic" with the other two normal hash board data cables (only the hash board is replaced), and first eliminate the problem of the data cable and the Antminer S17 control board.

2. Check whether the total voltage of the hash board is normal; if it is abnormal, you need to use a fluke 15B+ multimeter to check whether the voltage of each PIC, MOS tube, and boost circuit is abnormal.
3. Measure whether the voltage of the RI signal is normal and directly find the RI signal of a group of chips on the edge of the domain from the middle domain for detection. If it is normal, we will check it forward, and if it is abnormal, we will check it backward.
The RI signal transmission direction of the S17 hash board is shown in the following figure (from No.48 to No.1):

4. If the kernel log and test fixture test results show "ASIC=0 or NO hash board", mainly check whether the voltage of the chip RI signal and the ground value is abnormal. If there is any abnormality, most of them are caused by chip pseudo soldering. First, re-solder it twice. If it cannot be solved, replace the faulty BM1397 chip.

How to repair antminer T17 Hashboard and repair guide manual download

How to repair antminer T17 Hashboard and repair guide manual download This version contains the basic circuit schematic diagram and chip signal direction and voltage introduction We currently publish in Chinese and the English version will be released soon Basic overview: Antminer T17 single hash board uses a total of 30 hash chips, the model is "BM1397", and the signal direction is sequentially transmitted from U1 to U30. Signal direction: "CLK / CO / BO / RST", transferred from U1 to U30, "RI" is transferred from U30 to U1 It also passes 5 test points for testing and maintenance The five test points are: CLK-CO-RI-BO-RST (Please note: The location of the test points in different voltage domains are also different, please refer to the picture notes) For notes and instructions on the test points, please see the following articles: The whole board has 30 chips, divided into 10 voltage domains, and each voltage domain contains 3 chips For the description of

How to repair ASIC miner hash board

How to repair ASIC miner hash board Important parts of ASIC miners – Hash board One  ASIC miner consists of 3 to 5 Hash board, a control board, a casing, and software, among which the Hash board are easiest  to broken. because the ASIC bitcoin miner hash board consists of many serially connected ASIC chips. When they work, they will be in a high-temperature environment for a long time. In this environment, it is easy to burn the chip or scatter the solder due to high temperature which makes the hash board or the mining machine unable to work and no hash rate. How to quickly detective which chips broken it’s the most important when we repairing ASIC miners The Antminer chips fixture fast efficient and easy to use Bitmain Antminer repair inspection tool The ASIC bitcoin miner hash board consists of many serially connected ASIC chips. When they work, they will be in a high-temperature environment for a long time. In this environment, it is easy to burn the chip or scatter the solder du
