antminer s19 pro hashboard Fundamentals Explained
b) If one chip are available in move a), it implies that the primary chip and also the previous circuit are ordinary. Use a similar technique to check the next chips. For example, if the 1V2 exam stage and RO exam issue amongst the 38th and 39th chips are shorter-circuited, Should the log can discover the 38th chip, then there's no issue with the very first 38 chips. If 0 chips remain identified, very first Test if the 1V2 is regular.
This spare element is particularly suitable for quick upkeep and repair on the S19 Professional hash board, making sure seamless operations and substantial-effectiveness mining.
Look at the welding high-quality of the heat-sensitive chip along with the compact warmth sink. The deformation of the big heat sink content will bring about lousy heat dissipation from the chip and have an impact on the temperature variance. Figure five-14 four. Phenomenon: One board detection chip is just not comprehensive (PT1/PT2 stations) a) LCD Exhibit ASICNG: if (0), to start with measure the whole voltage of the measuring domain and also the Improve circuit 19V is standard, and after that utilize the shorter-circuit probe to quick-circuit the RO test position plus the 1V8 exam place among the main and the 2nd chip, and afterwards work This system to discover the chip. Looking at the serial port log, if 0 chip remains to be found at this time, It will probably be certainly one of the next cases: a-one) Use a multimeter to measure if the voltages on the 1V8 and 0V8 examination details are 1.8V or 0.8V. Otherwise, it indicates which the one.8V or 0.8V LDO circuit of this area is irregular, or The 2 ASIC chips of the domain is not really soldered effectively; most of the are a result of quick circuits of 0.8V, 1.8V patch filter capacitors (measure the resistance of your patch filter capacitors connected to the back and front of your PCBA). a-two) Check whether the circuits of U1 and U2 are irregular, for instance resistance welding, and so on.
(3) When changing the chip, it is necessary to plant tin within the pins from the chip to start with, then solder it on the hash board. Apply warmth-conducting gel evenly to the surface of your chip then install the massive heat sink.
Ordinary means There's a issue with chips right after 38 chips. Keep on utilizing the dichotomy strategy right until you discover the problematic chip. Assuming that there is a problem with the N-th chip, then when 1V2 and RO in between the N-one and N chips are brief-circuited, the N-one chip can be found. But when 1V2 and RO amongst the N and N+1 chips are shorter-circuited, the whole chip can't be discovered.
● Following the program examination is handed (the short-circuit test of the final plan take a look at is important to stay away from the chip or other components getting burnt because of the quick circuit when the facility is turned on), Get It Here the chip take a look at may be executed Together with the hashboard tester, as well as the positioning could be determined in accordance with the examination results of the hashboard tester.
three. Soon after repairing, the hashboard has to be examined for over two times being Alright prior to it might pass!
The Antminer S19 is a powerful miner, but its performance is often hindered by faulty hashboards. By changing them with our upgraded hashboards, it is possible to make certain that your miner is usually operating at its utmost prospective.

six. Following the repair, the hash board has to pass more than two situations to generally be judged as a good product when tested by the exam fixture. For The very first time, immediately after replacing the extras, look forward to the hash board to cool down, utilize the check jig to check the pass, and afterwards set it apart to chill down. The second time, wait around a couple of minutes to the hash plate to chill entirely before screening all over again.
Referring into the examination procedure doc, the general challenges that come up are assembly process challenges and Manage board system issues. Common challenges consist of The shortcoming to detect the IP, irregular range of detected lovers, and irregular detected chain.
Examine whether or not the conductive copper bar is in poor Make contact with, Look at if the ability Manage wire is free or weakened, and replace the power supply.
four) No hash price immediately after operating for your time period, mining pool link is interrupted: check the network.
