Everything about hashboard antminer s19

1. Utilize the 19 series hashboard tester SD card reflash software for The very first time to update the hashboard tester Management board FPGA, unzip it and copy it to the SD card, after which insert the card into the hashboard tester card slot; electrical power on for about one minute and look ahead to the Command board indicator to double flash three occasions, then the update is completed; (if It's not necessarily up to date, it could trigger a specific chip to report fault during the test)

Repair technique: check the appearance, evaluate the chip capacitor or resistance in front, usually It is a result of poor chip soldering or even a chip capacitor, resistor damaging or abnormal resistance;

c) Liquid crystal display display ASIC113: (Reporting 113), it signifies that the hash board can detect 114 chips at 115200 baud fee, but only 113 chips are discovered at 12M baud rate, and 1 chip could not be discovered at 12M baud amount; Repair system: Utilizing the dichotomy technique, short-circuit the 1V8 examination place plus the RO exam position involving the 38th and 39th chips With all the shorter circuit probe. In the event the log can discover 38 chips, there's no dilemma with the first 38 chips; if brief-circuiting the 47th chip, though the log reviews forty sixth, it indicates the 47th chip cannot be detected, and there is no problem While using the visual inspection. Generally, the 47th chip shall be replaced; Determine five-fifteen d) LCD Exhibit ASICNG: (X, a particular chip is fixedly noted), There's two situations: d-one) The very first circumstance: the take a look at time is basically the same as The great board (commonly the value of X will likely not adjust every time you exam) (test time refers to the time from when the beginning take a look at button is pressed to time when the result of ASICNG: (X) is displayed about the LCD). This case is likely to be attributable to the irregular resistance welding on the front and rear CLK, CI, and BO with the Xth chip, so consumers shall give attention to these 6 resistors. The little likelihood is because of X-one, X, X+1, that is certainly, Amongst the three chips, the next pins irregular welding problems on the chip take place: Figure five-16 d-two) The second case: the examination time is nearly 2 times as long as The great board (from time to time the worth of X will transform when you exam, and from time to time X=0); presently, the log typically has the subsequent details (the pink selection is just not 13 someday, based on which seat the hash board tester is linked to); through the test, suppose the area voltage of many of the fields in front of the abnormal placement is nearly less than 0.3V, as well as domain voltage on the back fields are Nearly all increased than 0.34V. This case is attributable to the chip not remaining soldered effectively, generally one.8V, 0.8V, RXT, CLK will not be soldered well. It is suggested to straight measure the area voltage to Track down which domain is the condition. The 1V8 and RO short-circuit approach Utilized in area a) can also Identify the Price Here abnormal posture;

Upkeep process: Examine the appearance and measure the capacitance or resistance of your entrance chip. Generally, it is actually attributable to bad chip welding or hurt and irregular resistance of a specific chip capacitor or resistor, or problems with the chip itself;

8V, one.8V patch filter capacitors (measure the resistance of the patch filter capacitors linked to the back and front in the PCBA)

● When finding the faulty chip, the chip should be welded all over again. The tactic is to add flux throughout the chip (preferably no-clear flux), and warmth the solder joints from the chip pins to the dissolved state to prompt the chip pins and pads to re-operate in and collect the tin, so as to accomplish the effect of tinning again. Should the fault continues to be the exact same after re-soldering, you can specifically substitute the chip.

Our alternative hashboards are not only refurbished, They can be upgraded to ensure far better functionality and trustworthiness than the initial. Just about every hashboard goes by way of a arduous Restoration system which makes them far more reliable than new kinds straight from your producer.

Windows mining Our mining monitoring and management software for Home windows GPU rigs is the perfect Remedy for those who choose to mine on their own Home windows devices.

Make sure you watch out to not believe that any impostors, please Test our accurate Get in touch with information and beware of getting deceived acquiring ripped off, and shedding dollars. please Examine our suitable Get hold of way: In this article

In keeping with this method, discover the chip that also has the long-time period working failure immediately after a certain chip is short-circuited. Generally, it's because of a certain chip harmful, so just substitute it;

● When locating the defective chip, the chip must be welded once again. The tactic is to add flux round the chip (if possible no-cleanse flux), and warmth the solder joints with the chip pins to a dissolved state to prompt the chip pins and pads to re-run in and accumulate the tin, In order to obtain the effect of tinning once more. If your fault continues to be exactly the same right after re-soldering, you'll be able to specifically replace the chip. ● The repaired hash board is often judged as a good solution with a lot more than two passes when screening With all the hash board tester. For the first time, after changing the pieces, look ahead to the hash board to chill down, make use of the hash board tester to test, and after the examination is passed, established it apart and after that awesome it down. For the 2nd time, just after a few minutes when the hash board cools down, test once again. 0 About goods purchase, be sure to Get hold of our income manager:

three. When sensor NG is exhibited around the Liquid crystal display monitor of your fixture, the check reading through temperature is abnormal. Be sure to Keep to the methods down below to troubleshoot:

② The next circumstance: Micro-quick circuit among alerts (0-numerous ohms), caused by the modest resistor price of the chip pins, first use a heat gun to solder and see if it is OK;

Carry on to research with dichotomy until finally the problematic chip is found. Assuming that there is a problem Along with the Nth chip, once the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-one chips can be found, but when the 1V8 and RO between the Nth and N+1th chips are limited circuited, the complete chip can't be located.
