PatternNG is a problem that occurs resulting from major distinctions inside the characteristics of a particular chip in comparison with other chips. To resolve this situation, it's been recognized that the chip’s die is ruined and wishes to get replaced.
To test repairing and replacing the chip, examination the chip initially and afterwards do the purposeful examination just after it passes. The purposeful check should ensure that the small heatsink is welded effectively, the big warmth sink is put in, and also the thermal adhesive gel is utilized evenly.
Get the most effective mining general performance out of your respective Antminer S19 by utilizing the correct application. Be a part of minerstat and locate the most suitable computer software for the set up.
three. Make the SD card In keeping with the requirements. If the hash board is just mounted with an individual-sided warmth sink and detect the chip, instantly decompress the compressed deal to help make the SD card;
To summarize, the repair procedure with the hash board requires regime inspection, chip check, fault localization, and testing and verification. Through these measures, the defective chip could be Positioned and repaired or changed, plus the hash board is usually tested to ensure it's working correctly.
③ Once the Visible inspection is Okay, the impedance of every voltage domain might be detected to detect whether There exists a small circuit or an open circuit. If observed, it need to be handled to start with.
Remember to be cautious never to imagine any impostors, you should Examine our suitable Make contact with information and beware of remaining deceived having ripped off, and shedding income. make sure you Examine our ideal Call way: Here
Verify the serial port log, if 0 chip remains to be discovered at the moment, Will probably be amongst the subsequent scenarios:
(2) Utilize the take a look at fixture in the V2.1010 control board (its model is ZJ0001000001), the positive and detrimental poles of the facility source of your check fixture have to be installed with a discharge resistor, and it is recommended to work with a cement resistor of 25 ohms and earlier mentioned 100W.
If the chip will not be located, check for feasible challenges like abnormal voltage within the 1V8 and 0V8 check factors, troubles Together with the U1 and U2 circuits, resistance of R8 or R9, and if the pins of the initial chip are soldered nicely.
If the massive heat sink content is deformed, it can result in bad warmth dissipation of the chip and have an effect on the temperature distinction.
If there is no difficulty With all the connection, you could conduct the PT2 examination on the single board to examine whether the take a look at can move. If it could be passed, most certainly the Regulate board is defective. When the take a look at fails, use the PT2 servicing process to repair.
a-three) Evaluate the resistance of R8 or R9 which has a multimeter to examine whether it is within 10 ohms along with the looking at will not jump randomly. Otherwise, you should switch both of these resistors. a-four) Check out If your pins of the main chip usually are not soldered properly (it had been located in repair which the pins are tinned observing with the side, however the pins usually are not stained with tin in any respect when the chip is removed). b) If 1 chip are available in action a), it implies that the 1st chip as well as past circuit are fantastic. Use an analogous system to check the next chips. Such as, quick-circuit the 1V8 test level along with the RO check issue among the 38th and 39th chips. If your log can find 38 chips, the main 38 chips have no challenge; if you still discover 0 chips, Verify the 1V8 to start with; if It really is ordinary, it means that there's a difficulty Using the chip immediately after 38. Carry on to research with dichotomy until eventually the problematic chip is located. Assuming that there's a trouble With all the Nth chip, if the 1V8 and RO involving the N-1th and Nth chips Get It Here are brief-circuited, N-one chips are available, but if the 1V8 and RO involving the Nth and N+1th chips are shorter circuited, all the chip cannot be discovered.
a. Make sure the enthusiast connector has become plugged into the socket and there's no injury to the lover cable. (Below photos are bad socket and lousy cable illustrations)
