Be a part of the global Group of miners who have confidence in minerstat to elevate their mining sport. Are you presently willing to unlock your mining likely?
Repair approach: Verify the appearance, measure the chip capacitor or resistance in front, commonly it's because of lousy chip soldering or a chip capacitor, resistor harming or irregular resistance;
c) LCD Show ASIC113: (Reporting 113), it ensures that the hash board can detect 114 chips at 115200 baud level, but only 113 chips are observed at 12M baud fee, and a person chip could not be discovered at 12M baud fee; Repair strategy: Using the dichotomy process, small-circuit the 1V8 test issue and the RO check level amongst the 38th and 39th chips While using the limited circuit probe. When the log can find 38 chips, there isn't a dilemma with the first 38 chips; if short-circuiting the 47th chip, even so the log stories forty sixth, it implies that the 47th chip can't be detected, and there's no challenge with the Visible inspection. Usually, the 47th chip shall get replaced; Determine five-15 d) LCD Display screen ASICNG: (X, a certain chip is fixedly noted), there are two scenarios: d-one) The very first case: the exam time is largely the same as The nice board (ordinarily the value of X is not going to modify each time you test) (examination time refers back to the time from when the start examination button is pressed to the time when the result of ASICNG: (X) is displayed to the Liquid crystal display). This situation is probably going being caused by the abnormal resistance welding from the front and rear CLK, CI, and BO on the Xth chip, so users shall give attention to these 6 resistors. The little probability is because of X-one, X, X+one, that is definitely, among the three chips, the following pins irregular welding conditions from the chip come about: Determine five-sixteen d-two) The next situation: the exam time is sort of two times as long as the good board (from time to time the worth of X will improve each and every time you examination, and at times X=0); presently, the log typically has the subsequent info (the pink number will not be thirteen someday, determined by which seat the hash board tester is linked to); through the examination, presume which the area voltage of all of the fields before the abnormal place is nearly less than 0.3V, and the domain voltage on the back again fields are almost all bigger than 0.34V. This situation is due to the chip not currently being soldered effectively, generally 1.8V, 0.8V, RXT, CLK usually are not soldered nicely. It is suggested to straight evaluate the area voltage to Find which domain is the issue. The 1V8 and RO quick-circuit strategy Employed in part a) might also Track down the irregular placement;
log-area voltage print command The precise functions are as follows: Open up putty , enter the IP on the miner in query and click Open up Determine 6-7 2. Enter the person name, password and take a look at command to check the NONCE response status and the status of voltage area. In the event the NONCE and area voltage are abnormal, consumer can accomplish measurement and routine maintenance determined by the printed irregular chip.
1. Pay attention for the operation technique when replacing the chip. Right after replacing any add-ons, the PCB board shall have no clear deformation.
Just after managing for a time frame, there is no hashrate, along with the connection on the mining pool is interrupted, Look at the network.
If there isn't any 3.3V output, Look at the connection position with the hash board tester cable as well as the hash board.
Windows mining Our mining checking and administration software program for Home windows GPU rigs is the proper Option for people who prefer to mine on their Windows equipment.
You should watch out never to feel any impostors, please check our accurate Get in touch with details and beware of currently being deceived acquiring scammed, and shedding revenue. be sure to Test our right Speak to way: Below
Don’t Permit defective hashboards have an impact on your mining general performance. Up grade your Antminer S19 Professional with our trustworthy and large-performing alternative hashboards now.
① First off, visually inspect the hash board to determine if there is any deformation or burning of your PCB. When there is any phenomenon, it has to be dealt with very first.
Likely, the IP cannot be identified resulting from irregular Procedure. Seek advice from the very first level for troubleshooting.
a-three) Evaluate the resistance of R8 or R9 having a multimeter to examine whether it is within ten ohms and also the examining will likely not bounce randomly. Otherwise, be sure to change these two resistors. a-4) Check out In case the pins of the 1st chip are not soldered very well (it was found in repair which the pins are tinned observing within the aspect, nevertheless the pins are certainly not stained with tin in the slightest degree in the event the chip is taken off). b) If just one chip are available in action a), it signifies that the very first chip and also the prior circuit are good. Use an identical method to check the next chips. One example is, quick-circuit the 1V8 take a look at level and also the RO exam level concerning the 38th and 39th chips. When the log can discover 38 chips, the primary 38 chips haven't any dilemma; if you continue to obtain 0 chips, Check out the 1V8 first; if It truly is normal, it means that there is a dilemma With all the chip immediately after 38. Carry on to analyze with dichotomy until the problematic chip is located. Assuming that there is a challenge with the Nth chip, in the event the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-1 chips can Get It Here be found, but when the 1V8 and RO among the Nth and N+1th chips are brief circuited, your entire chip can't be observed.
Confer with the voltage price array explained by the signal pattern. If your calculated voltage worth is too huge, it might be compared With all the calculated values of adjacent teams for judgment.
