Be part of the global Local community of miners who have confidence in minerstat to elevate their mining recreation. Will you be all set to unlock your mining probable?
Repair strategy: Look at the looks, measure the chip capacitor or resistance in front, usually It is brought on by inadequate chip soldering or even a chip capacitor, resistor harming or abnormal resistance; VI. Handle Board Dilemma Triggering the next Issues 1. The entire miner does not function 1) Look at whether the voltages at a number of voltage output factors are usual. U8 may be disconnected very first if 3.3V is short-circuited. If it is still small-circuited, the CPU may be unplugged for measurement. For other voltage abnormalities, commonly change the corresponding converter IC. 2) When the voltage is normal, remember to Verify the welding standing with the DDR/CPU. 3) Try and update the flash method with SD card; When the miner of which the Regulate board has been reflashed needs to start normally, the next two ways are demanded: a) Once the card Restoration is passed, the green LED indicator will probably be often on, and the ability shall be restarted; b) Look forward to 30s immediately after powering on once more (time study course of turning on OTP).
② Visually inspect no matter whether there are actually evident indications of burnt areas, elements impression offset or missing components, etc.
(three) When replacing the chip, it's important to plant tin to the pins in the chip initial, after which solder it into the hash board. Utilize heat-conducting gel evenly within the surface of the chip after which you can put in the big heat sink.
③ Utilize a multimeter to evaluate the resistor of R8 or R9 to check out whether it is within 10 ohms, as well as the looking through will not likely leap randomly. If not, switch the two resistors;
d-2) The second scenario; the test time is almost two times as long as The great board (sometimes the worth of X will transform each and every time you take a look at, and in some cases X=0); at the moment, the log normally has the next information and facts (the pink number is not thirteen someday, dependant upon which seat the hashboard tester is connected to); over the test, believe the area voltage of every one of the fields in front of the irregular placement is almost below 0.
Examine the welding good quality of your Go Here chip which connects sensor as well as the modest heat sink. The deformation of huge warmth sink product will induce lousy heat dissipation on the chip and have an impact on the temperature difference.
Check out the serial port log, if 0 chip is still observed at the moment, It will likely be certainly one of the following predicaments:
Proceed to analyze with dichotomy till the problematic chip is discovered. Assuming that there's a trouble with the Nth chip, once the 1V8 and RO involving the N-1th and Nth chips are shorter-circuited, N-1 chips can be found, but in the event the 1V8 and RO among the Nth and N+1th chips are shorter circuited, the entire chip can not be found.
Measure irrespective of whether There may be output on the next pin of U3 and also the voltage is about three.3V; if Sure, make sure you go on to troubleshoot the problem; if there isn't a 3.3V, remember to Test the connection standing on the hashboard tester cable as well as hashboard is Alright, and reprogram the PIC.
Does any info on this website page looks incorrect and you prefer to for us to check it? Make clear The difficulty with just as much info as feasible.
The hash board is a crucial element of the copyright mining machine. If It's not necessarily functioning adequately, it may cause significant troubles. This informative article aims to offer troubleshooting ways for typical faults associated with the hash board.
a-three) Evaluate the resistance of R8 or R9 having a multimeter to check whether it is inside 10 ohms as well as the examining won't jump randomly. Otherwise, be sure to replace these two resistors. a-4) Verify In the event the pins of the primary chip are certainly not soldered nicely (it absolutely was located in repair the pins are tinned observing from your side, but the pins usually are not stained with tin in any way once the chip is removed). b) If a person chip can be found in phase a), it indicates that the first chip plus the preceding circuit are great. Use an analogous process to check the next chips. As an example, short-circuit the 1V8 examination place along with the RO exam level concerning the 38th and 39th chips. In case the log can discover 38 chips, the primary 38 chips haven't any difficulty; if you continue to obtain 0 chips, Examine the 1V8 to start with; if It can be standard, this means that there's a issue With all the chip right after 38. Go on to investigate with dichotomy until finally the problematic chip is observed. Assuming that there's a dilemma Using the Nth chip, if the 1V8 and RO concerning the N-1th and Nth chips are short-circuited, N-one chips can be found, but if the 1V8 and RO in between the Nth and N+1th chips are quick circuited, all the chip can't be observed.
