five. Inside the exam of repairing and changing the chip, the chip must be examined 1st, after which the functionality examination shall be carried out right after passing. The function examination should be sure that the tiny heat sink is welded qualified. When putting in the massive warmth sink, the surface area on the chip have to be evenly coated with thermal gel along with the cooling supporter shall be at total velocity.
If there is Untrue welding, it should be re-soldered. When there is problems, it needs to be calculated whether or not the resistance value is typical. Change the corresponding elements abnormally, and Examine the compact board soldered about the PCB; the smaller board is demonstrated while in the figure below.
Do-it-yourself production of electric power adapter cable: Use thick copper wires to connect the constructive and damaging poles of the facility source to the facility source and hash board. It is recommended to utilize 4AWG copper wire which has a size of less than 60cm for the hash board power.
(3) Abnormal temperature: The maximum PCB temperature set by our checking procedure cannot exceed 90C/194T.
2. When using the S19 pro+ Hyd series test fixture for the first time, utilize the SD card flash application to update the FPGA to the fixture Management board, unzip it and duplicate it on the SD card, and insert the card into the fixture card slot.
d-two) The second case; the take a look at time is sort of 2 times as long as the good board (often the value of X will improve whenever you examination, and often X=0); presently, the log usually has the following details (the red amount is just not 13 sometime, based upon which seat the hashboard tester is linked to); over the examination, assume the domain voltage of every one of the fields in front of the abnormal position is nearly below 0.
Preserving an Antminer S19 can be a frightening job should you don’t understand what to search for. Understanding The essential methods of upkeep and troubleshooting is critical in keeping your miner working easily and efficiently. On this information, We're going to go over the basics of Antminer S19 routine maintenance, from regimen inspections to tests hash boards and replacing faulty chips.
2. Following the plan inspection is Alright (brief circuit detection of basic plan inspection is necessary, so as to not burn off the chip or other supplies resulting from short circuit when the facility is turned on), the chip could be examined with the check fixture, and the judgment and positioning may be carried out based on the take a look at results of the check fixture;
PatternNG is due to the large distinction between the features from the chip and other chips. At the Contact Here moment, it is identified that the chip die is destroyed, so just swap the chip. Based on the log info, the substitute principles are as follows:
(two) U1 cannot be utilised on other number of styles if the OTP purpose is enabled around the Regulate board.
Keep on this process and quick-circuit the next chips one after the other until a chip is found that also brings about long-phrase operating failure even after being quick-circuited. This failure is often on account of harm to that exact chip, and so it ought to be replaced.
Home windows mining Our mining monitoring and management computer software for Home windows GPU rigs is the proper Remedy for individuals who choose to mine on their Home windows machines.
four. For your exam of chip servicing and substitution, it's important to detect the chip very first, and after that do a useful examination right after passing. The practical examination should make certain that the small warmth sink is soldered perfectly and the large heat sink is mounted in place (Each and every thermal conductive adhesive should be used evenly in advance of setting up the big warmth sink).
