4mm); when replacing a new chip, you'll want to tin the chip pins and afterwards solder towards the hashboard, after which lock significant heat sinks following applying thermal gel evenly about the chip floor.
(3) Swap the a single with a better reply as well as the 1 which has a decrease reply. Following the swap, examination the hash board once more to examine if the reply of the ASIC chip is typical. If it is irregular, measure whether the voltage In this particular domain is reduced than the normal worth.
c) Liquid crystal display Display screen ASIC113: (Reporting 113), it means that the hash board can detect 114 chips at 115200 baud rate, but only 113 chips are observed at 12M baud charge, and one particular chip could not be uncovered at 12M baud rate; Repair method: Utilizing the dichotomy strategy, quick-circuit the 1V8 test issue plus the RO exam position among the 38th and 39th chips While using the quick circuit probe. If your log can discover 38 chips, there's no difficulty with the very first 38 chips; if shorter-circuiting the 47th chip, but the log reviews 46th, it implies that the 47th chip can't be detected, and there's no challenge with the visual inspection. Typically, the 47th chip shall get replaced; Determine 5-fifteen d) LCD Exhibit ASICNG: (X, a particular chip is fixedly described), there are two predicaments: d-1) The primary scenario: the examination time is essentially the same as The great board (ordinarily the value of X won't transform every time you exam) (exam time refers back to the time from when the beginning exam button is pressed to some time when the results of ASICNG: (X) is exhibited within the Liquid crystal display). This case is likely being due to the irregular resistance welding of your front and rear CLK, CI, and BO on the Xth chip, so end users shall give attention to these 6 resistors. The smaller probability is due to X-one, X, X+1, that may be, among the three chips, the following pins abnormal welding conditions of the chip happen: Determine 5-sixteen d-two) The next circumstance: the examination time is almost 2 times as long as The great board (sometimes the worth of X will adjust each and every time you examination, and occasionally X=0); right now, the log ordinarily has the following info (the purple selection will not be thirteen someday, depending on which seat the hash board tester is connected to); through the exam, presume which the domain voltage of each of the fields before the irregular situation is sort of fewer than 0.3V, plus the domain voltage of the again fields are Virtually all greater than 0.34V. This situation is brought on by the chip not staying soldered well, usually one.8V, 0.8V, RXT, CLK are certainly not soldered well. It is recommended to specifically evaluate the domain voltage to Find which domain is the problem. The 1V8 and RO quick-circuit process Utilized in portion a) may Identify the irregular posture;
As shown in the determine down below, the very first hash board has no hash charge immediately after operating for approximately three minutes.
Normal signifies There's a difficulty with chips following 38 chips. Continue on using the dichotomy process right up until you discover the problematic chip. Assuming that there's a problem With all the Antminer s19 Pro Hashboard N-th chip, then when 1V2 and RO amongst the N-one and N chips are limited-circuited, the N-one chip can be found. But when 1V2 and RO among the N and N+one chips are limited-circuited, the entire chip can't be located.
Just in case several chips in the same domain Possess a small response charge, the one Along with the reduce nonce in that area ought to get replaced.
Upkeep technique: Over the PT2 exam, look at the serial port print log. It will likely be brought on by an error from the sign up deal with of a particular chip. Just change the BM5 chip as demonstrated in Figure five-19 (asic starts from 0).
The Antminer S19 is a strong miner, but its functionality can be hindered by faulty hashboards. By changing them with our upgraded hashboards, you can be sure that your miner is usually managing at its most likely.
① The particular Examination technique is as follows: Very first, conduct a single-board PT2 take a look at to check whether or not the general performance with the hash board is standard.
(1) Unexpected ability failure or less than 30s in the whole process of opening OTP will lead to the Management board to fail to open up the OTP function, as well as Command board will not likely start off (not connected to the Internet).
six. Following the repair, the hash board has to go over two moments for being judged as an excellent solution when examined through the test fixture. For The 1st time, just after changing the equipment, await the hash board to chill down, utilize the check jig to check the go, and afterwards set it apart to chill down. The second time, wait around a few minutes for that hash plate to chill completely before tests once again.
Almost certainly, the IP can not be observed as a result of abnormal operation. Check with the 1st issue for troubleshooting.
three. The SD tests card will be produced In accordance with the necessities, and the double-sided warmth sink 8-times Sample take a look at ought to make an SD card, as proven within the determine beneath;
1. Make reference to the voltage benefit selection explained because of the sign pattern. If the measurement encounters a significant deviation on the voltage benefit, it may be compared Using the calculated price of the adjacent team to determine.
