38. Proceed to use the binary system to check right up until the problematic chip is located. Assuming that there is a issue with the Nth chip, if the 1V2 and RX among the N-1th chip along with the Nth chip are limited-circuited, the N-1 chip are available; Having said that, once the 1V2 and RX concerning the N and N+1 chips are small-circuited, the entire chip cannot be discovered.
two. For The 1st time utilize the 19 collection check fixture SD card flash method to update the FPGA Regulate board on the tester, copy it to the SD card immediately after decompression, and insert the SD card in to the fixture card slot: Electric power on for approximately one moment, and look ahead to the red and inexperienced indicators to the control board to flash three times in succession, then the update is complete (if it is not updated, it may well trigger a hard and fast chip being noted as faulty throughout the exam).
Look at the welding high quality of the warmth-delicate chip along with the smaller heat sink. The deformation of the massive warmth sink product will cause weak heat dissipation in the chip and have an effect on the temperature distinction. Figure five-14 four. Phenomenon: One board detection chip is not finish (PT1/PT2 stations) a) Liquid crystal display Show ASICNG: if (0), to start with evaluate the whole voltage of the measuring domain plus the Enhance circuit 19V is normal, then utilize the quick-circuit probe to limited-circuit the RO check level along with the 1V8 test place concerning the initial and the next chip, and after that function the program to discover the chip. Looking at the serial port log, if 0 chip remains to be uncovered right now, Will probably be amongst the following situations: a-one) Use a multimeter to evaluate whether the voltages in the 1V8 and 0V8 check factors are one.8V or 0.8V. If not, it indicates the 1.8V or 0.8V LDO circuit of the domain is irregular, or the two ASIC chips of this domain isn't soldered effectively; most of this are attributable to short circuits of 0.8V, one.8V patch filter capacitors (measure the resistance on the patch filter capacitors connected to the back and front with the PCBA). a-two) Examine whether the circuits of U1 and U2 are abnormal, including resistance welding, and so forth.
As demonstrated within the figure under, the primary hash board has no hash amount immediately after working for about three minutes.
PatternNG is attributable to the large difference between the traits on the chip and other chips. At the moment, it is actually observed that the chip die is broken, so just swap the chip. Based on the log details, the alternative regulations are as follows: If the appearance of the chip will not be broken, just change the chip with the lowest response charge in Every domain. The next determine demonstrates one of several exam logs, it may be noticed with the log which the reaction charge of four chips asic[36][37][43][seventy five] is lower.
In the event the miner still loses hashrate, decrease the frequency as well as other situations stay unchanged. Allow the miner mine to find out if it's going to eliminate hashrate and if the hash board will strike X. If it however hits X in dropping hashrate, then remove the heat sink of your hashboard for mining and look forward to the hashrate to fall.
Windows mining Our mining checking and management application for Windows GPU rigs is the proper Alternative for many who prefer to mine on their own Windows equipment.
The repaired hash board might be judged as an excellent solution with greater than two passes when examined Using the hash board tester.
Home windows mining Our mining monitoring and administration application for Home windows GPU rigs is the proper Remedy for those who choose to mine on their own Windows devices.
Verify the LCD Show ASICNG by measuring the total voltage on the measuring domain and Improve circuit.
● The repaired hashboard might be judged as a fantastic products with more than two passes when tests Using the hashboard tester. For the first time, after changing the pieces, look ahead to the hashboard to chill down, use the hashboard tester to check, and following the examination is passed, established it aside and then cool it down. For the 2nd time, immediately after a few minutes in the event the hashboard cools down, test all over again.
3. The exam SD card might be produced As outlined by the requirements, as well as double-sided heat sink 8-times Patter exam has to make an SD card, as demonstrated within the figure down below;
six. Determine the upkeep Buy Here station item and the corresponding examination program parameters and test fixtures.
PS: If the hash board just isn't run or run off in accordance with the test sequence, leading to U2 and U10 to burn off out, it can report 0 when tests the chip;
