On the whole, the domain voltage is going to be irregular from the problematic domain. Then measure the RI signal to find out exactly where the RI sign is interrupted. Should the RI signal disappears, it may mainly be determined that the chip is short-circuited or weakened immediately after getting tinned.
2. For The very first time utilize the 19 collection check fixture SD card flash software to update the FPGA Command board with the tester, duplicate it on the SD card just after decompression, and insert the SD card into the fixture card slot: Ability on for approximately 1 moment, and wait for the crimson and green indicators about the control board to flash three occasions in succession, then the update is total (if It's not at all up-to-date, it may well bring about a hard and fast chip to generally be described as faulty through the test).
c) Liquid crystal display Show ASIC113: (Reporting 113), it ensures that the hash board can detect 114 chips at 115200 baud fee, but only 113 chips are located at 12M baud level, and one chip couldn't be located at 12M baud level; Repair approach: Utilizing the dichotomy method, small-circuit the 1V8 examination point and the RO exam level concerning the 38th and 39th chips Together with the small circuit probe. If the log can find 38 chips, there isn't any dilemma with the initial 38 chips; if short-circuiting the 47th chip, but the log stories forty sixth, it indicates which the 47th chip can not be detected, and there's no trouble With all the Visible inspection. Generally, the 47th chip shall be replaced; Figure 5-fifteen d) LCD display ASICNG: (X, a certain chip is fixedly claimed), there are two scenarios: d-1) The first case: the take a look at time is essentially the same as The great board (normally the value of X will likely not alter each time you exam) (test time refers to the time from when the start examination button is pressed to enough time when the result of ASICNG: (X) is shown around the Liquid crystal display). This example is likely being due to the abnormal resistance welding on the entrance and rear CLK, CI, and BO from the Xth chip, so consumers shall deal with these six resistors. The little probability is because of X-1, X, X+1, that's, Amongst the a few chips, the next pins abnormal welding conditions on the chip come about: Figure 5-sixteen d-two) The next circumstance: the examination time is almost two times as long as The great board (from time to time the value of X will transform anytime you take a look at, and often X=0); at this time, the log ordinarily has the subsequent details (the pink quantity isn't 13 someday, based on which seat the hash board tester is connected to); over the examination, think which the area voltage of every one of the fields before the irregular posture is almost under 0.3V, and also the domain voltage with the back fields are almost all better than 0.34V. This situation is brought on by the chip not getting soldered very well, ordinarily one.8V, 0.8V, RXT, CLK aren't soldered well. It is usually recommended to directly measure the area voltage to Identify which area is the problem. The 1V8 and RO quick-circuit method used in part a) may also Identify the abnormal situation;
a) Liquid crystal display Display screen ASICNG: if (0), very first measure the overall voltage of the measuring area and the Increase circuit 20V is typical, and then utilize the short circuit probe to short-circuit the RO check stage as well as 1V8 check issue between the very first and the next chip, after which function the program to locate the chip. Look at the serial port log, if 0 chip remains to be observed presently, It will probably be amongst the following circumstances: a-one) Utilize a multimeter to measure if the voltages for the 1V8 and 0V8 examination points are 1.8V or 0.8V. If not, it suggests that the one.8V or 0.8V LDO circuit of the area is abnormal, or the two ASIC chips of the domain isn't soldered properly; most problems of the phenomenon are a result of quick circuits of 0.8V, one.8V patch filter capacitors (measure the resistance with the patch filter capacitors associated with the front and back on the PCBA). a-2) Check out whether or not the circuits of U2, U3 and U4 are abnormal, which include resistance welding, and so on. a-three) Evaluate the resistance of R232 or R233 with a multimeter to examine if it is in just 1 ohms along with the examining will likely not bounce randomly. If not, remember to switch both of these resistors. a-4) Look at Should the pins of the 1st chip are soldered perfectly (it had been found all through repair the pins are tinned observing with the aspect, nevertheless the pins are usually not stained with tin in the least if the chip is taken out). b) If one chip are available in stage a), it indicates that the very first chip plus the preceding circuit are good. Use the same method to check the next chips. By way of example, short-circuit the 1V8 check level as well as the RO check level concerning the 38th and 39th chips. If the log can discover 38 chips, the very first 38 chips have no challenge; if you continue to obtain 0 chips, check the 1V8 first; if It can be standard, this means that there is a problem While using the chips immediately after 38. Go on to investigate with dichotomy until finally the problematic chip is identified. Assuming that there is a issue While using the Nth chip, when the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-1 chips are available, but when the 1V8 and RO concerning the Nth and N+1th chips are limited circuited, all the chip can not be located.
The voltage of each and every voltage domain is about 1.35V. If there is a 14V powering, there is usually a site voltage, and also the output of the facility terminal of your hash board is calculated 1st; when there is a 14V powering but no area voltage, proceed to examine down.
If the miner that utilizes the Command board flashing must start Ordinarily, the following two actions are required:
You should be mindful to not believe any impostors, please Look at our accurate Get in touch with facts and Watch out for becoming deceived receiving cheated, and getting rid of money. be sure to Look at our right Get in touch with way: In this article
The Antminer S19 Pro is a strong miner, but its performance may be hindered by defective hashboards. By changing them with our upgraded hashboards, you can be sure that your miner is often functioning at its greatest potential.
37V. This situation is attributable to the chip not becoming soldered properly, commonly 1.2V, 0.8V, RXT, CLK are not soldered adequately. It is recommended to directly measure the area voltage to Identify the problematic area. The 1V2 and RO brief circuit system used in section a) could also Identify the irregular place
Home windows mining Our mining monitoring and management program for Home windows GPU rigs is the right solution for individuals who prefer to mine on their Windows devices.
● The repaired hashboard may be judged as a superb product with greater than two passes when tests Using the hashboard tester. For The very first time, following changing the parts, await the computing board to cool down, utilize the hashboard tester to test, and following the exam is passed, set it aside after which interesting it down. For the second time, right after a few minutes when the hashboard cools down, take a look at all over again.
Sample NG Purchase Here is because of the massive distinction between the traits with the chip and various chips. At this time, it is actually located the chip die is destroyed, so just exchange the chip. According to the log info, the alternative policies are as follows: If the appearance of the chip is not really broken, just replace the chip with the bottom response rate in Each individual area.
3V powering in the temperature sensor is ordinary; Test the chip connected to the temperature sensor. The material deformation of the big warmth sink will induce inadequate warmth dissipation from the chip and have an affect on the temperature big difference.
2) Significantly less url: Considerably less link refers to that Amongst the three boards, 1 piece is lacking. Most often, There exists a difficulty Together with the connection between the hashboard as well as Command board. Check out the cable to view when there is an open up circuit.
