3) Seek to update the flash method with SD card;In case the Regulate board card recovery device ought to begin Typically, the subsequent two methods are demanded:
To check repairing and replacing the chip, check the chip 1st and after that do the purposeful examination right after it passes. The practical exam should make sure that the compact heatsink is welded effectively, the massive warmth sink is put in, and also the thermal adhesive gel is applied evenly.
DIY creation of ability adapter cable: Use thick copper wires to attach the good and negative poles of the facility supply to the ability offer and hash board. It is usually recommended to work with 4AWG copper wire with a duration of less than 60cm to the hash board electricity.
six. The repaired hash board should be analyzed which has a exam fixture, and it should pass a lot more than two situations to be judged as a very good products. For The very first time, soon after replacing the add-ons, look ahead to the hash board to cool down, use the check fixture to check, and when is passed, put it on one facet in advance of cooling down. The second time, anticipate the hash board to chill down totally before screening.
When the following error concept "are unsuccessful to examine pic temp" seems inside the log, it signifies that the PIC is irregular.
minerstat isn't just Yet another calculator - It really is a robust mining platform that supports your copyright journey. Increase your gains, preserve valuable time, and optimize performance with our suite of top quality attributes:
Revitalize your Antminer S19 Professional’s functionality with our remarkable substitution hashboards. Expertly refurbished to make certain optimum mining performance, these hashboards are your Answer to faulty mining operations. Don’t Allow faulty hashboards sluggish you down.
(one) A sudden electrical power outage or lower than 30 seconds throughout the process of opening OTP will trigger the Management board to fall short to open up the OTP operate and the control board will never start off (not connect with the net).
Routine maintenance staff need to have electronic expertise, no less than a person yr of upkeep expertise, and proficiency in BGA/QFN/LGA packaging and welding technological innovation.
In accordance with this technique, discover the chip that also has the long-phrase running failure soon after a specific chip is short-circuited. Commonly, it is actually due to a specific chip damaging, so just substitute it;
six. Following the repair, the hash board needs to pass a lot more than two moments to get judged as a fantastic product or service when examined from the exam fixture. For the first time, after changing the add-ons, wait for the hash board to chill down, make use of the check jig to check the pass, after which set it apart to chill down. The second time, hold out a couple of minutes to the hash plate to chill totally ahead of testing yet again.
The method for repairing The problem is as follows: during the PT2 test, carefully check the serial port print log. Once the serial port has actually been working for an prolonged time frame, use a brief-circuit probe to quick-circuit RO and 1.
c) Contact Here LCD Show ASIC75: (Reporting 75), it signifies that the hash board can detect 76 chips at 115200 baud charge, but only 75 chips are found at 12M baud charge, and one chip couldn't uncover at 12M baud charge; Repair technique: Utilizing the dichotomy approach, small-circuit the 1V8 take a look at level as well as the RO test level involving the 38th and 39th chips with the short-circuit probe.
one. Pay attention into the operation strategy when changing the chip. After replacing any add-ons, the PCB board shall don't have any obvious deformation. Check out the alternative pieces and also the surrounding elements for open circuit and shorter circuit problems.
