38. Keep on to utilize the binary strategy to examine until finally the problematic chip is observed. Assuming that there's a dilemma With all the Nth chip, if the 1V2 and RX concerning the N-1th chip and also the Nth chip are quick-circuited, the N-one chip are available; However, in the event the 1V2 and RX between the N and N+one chips are short-circuited, the full chip can not be discovered.
d-one) The initial situation: the check time is essentially similar to the good board (ordinarily the worth of X won't transform each time you check) (examination time refers back to the time from when the beginning take a look at button is pressed to the result of ASICNG: (X) displayed over the Liquid crystal display). This example is likely for being a result of the abnormal resistance welding of the entrance and rear CLK, CI, and BO on the Xth chip, so consumers shall center on these six resistors. The smaller likelihood is because of X-1, X, X+1, which is, among the three chips, the subsequent pins irregular welding ailments in the chip come about: Figure 5-sixteen d-2) The second circumstance: the exam time is nearly 2 times as long as The nice board (from time to time the worth of X will adjust each and every time you examination, and at times X=0); at the moment, the log generally has the subsequent information and facts (the purple range just isn't 13, based upon which seat the hash board tester is connected to); throughout the exam, believe that the area voltage of all the fields in front of the irregular situation is sort of a lot less than 0.
c) Liquid crystal display Exhibit ASIC113: (Reporting 113), it signifies that the hash board can detect 114 chips at 115200 baud fee, but only 113 chips are observed at 12M baud charge, and 1 chip couldn't be observed at 12M baud level; Repair process: Using the dichotomy method, shorter-circuit the 1V8 examination level along with the RO test stage involving the 38th and 39th chips with the small circuit probe. If the log can discover 38 chips, there's no issue with the very first 38 chips; if limited-circuiting the 47th chip, though the log stories forty sixth, it signifies which the 47th chip can't be detected, and there's no dilemma Together with the visual inspection. Frequently, the 47th chip shall be replaced; Figure five-15 d) LCD Display screen ASICNG: (X, a particular chip is fixedly reported), there are two circumstances: d-1) The first circumstance: the check time is largely similar to The great board (commonly the value of X will not adjust every time you check) (examination time refers back to the time from when the start test button is pressed to some time when the results of ASICNG: (X) is exhibited over the Liquid crystal display). This case is likely for being caused by the irregular resistance welding of the front and rear CLK, CI, and BO of the Xth chip, so users shall focus on these six resistors. The smaller probability is because of X-one, X, X+1, that is certainly, among the a few chips, the next pins irregular welding disorders with the chip occur: Determine five-16 d-two) The next scenario: the check time is almost two times as long as The great board (often the worth of X will modify whenever you exam, and from time to time X=0); at the moment, the log commonly has the following facts (the purple quantity will not be 13 someday, based on which seat the hash board tester is linked to); in the exam, presume the area voltage of each of the fields before the abnormal placement is almost lower than 0.3V, plus the domain voltage in the back again fields are almost all increased than 0.34V. This case is due to the chip not remaining soldered nicely, normally 1.8V, 0.8V, RXT, CLK are certainly not soldered nicely. It is suggested to directly evaluate the area voltage to locate which area is the condition. The 1V8 Get It Here and RO limited-circuit strategy Employed in section a) might also locate the irregular position;
log-area voltage print command The particular functions are as follows: Open putty , enter the IP of your miner in concern and click on OPEN Determine six-seven 2. Enter the user title, password and test command to examine the NONCE response standing and the standing of voltage area. If the NONCE and area voltage are abnormal, consumer can execute measurement and routine maintenance based on the printed irregular chip.
If the chip’s physical appearance is just not harmed, the chip with the lowest response level in Every area should get replaced.
③ Once the Visible inspection is Alright, the impedance of each and every voltage area could be detected to detect regardless of whether You will find a quick circuit or an open circuit. If identified, it needs to be addressed to start with.
Our substitute hashboards are not simply refurbished, They are really upgraded to guarantee better effectiveness and dependability than the initial. Every hashboard goes via a arduous Restoration procedure that makes them a lot more trusted than new kinds straight from the company.

(two) Considerably less chains: it implies that among the list of 3 hash boards is missing. In such a case, most of the issues are a result of the connection between the hash board as well as the Manage board. Look at irrespective of whether You can find an open circuit in the cable.
● The repaired hashboard is often judged as a great solution with much more than two passes when testing With all the hashboard tester. For The 1st time, after replacing the elements, look ahead to the computing board to cool down, make use of the hashboard tester to check, and following the exam is handed, set it aside then neat it down. For the second time, right after a few minutes once the hashboard cools down, test once more.
Does any details on this page seems to be incorrect and you desire to for us to examine it? Reveal The problem with as much information as possible.
a-three) Evaluate the resistance of R8 or R9 having a multimeter to examine whether it is inside 10 ohms and the looking through is not going to soar randomly. Otherwise, make sure you exchange both of these resistors. a-four) Verify If your pins of the very first chip will not be soldered perfectly (it absolutely was found in repair that the pins are tinned observing from your aspect, although the pins are usually not stained with tin whatsoever once the chip is taken out). b) If just one chip are available in phase a), it signifies that the 1st chip as well as former circuit are good. Use an analogous system to check the following chips. By way of example, quick-circuit the 1V8 check point and the RO test issue involving the 38th and 39th chips. In case the log can find 38 chips, the 1st 38 chips don't have any dilemma; if you still come across 0 chips, Examine the 1V8 first; if It is really usual, it means that there's a problem Along with the chip right after 38. Go on to research with dichotomy till the problematic chip is observed. Assuming that there's a dilemma Using the Nth chip, when the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-1 chips can be found, but if the 1V8 and RO concerning the Nth and N+1th chips are small circuited, the whole chip cannot be located.
