one) Because the very first-era drinking water radiator are unable to meet the heat dissipation specifications, a drinking water pump really should be added in collection (or two water radiators in sequence) over the transformation;
A short while ago, many corporations boasting to get mining businesses imitate us and say that they're relevant to us, or that they're our branch businesses, that has caused shoppers to get deceived.
The voltage of each voltage domain is about 0.32V. If there is 16V electricity provide, typically it's area voltage. The precedence is supplied to evaluate the output of the facility source terminal with the hashboard and Test if the MOS is brief-circuited (measure the resistance in between pins 1, 4 and 8). If 16V has ability supply but no area voltage, go on to examine.
a) Liquid crystal display Exhibit ASICNG: if (0), very first evaluate the entire voltage with the measuring domain and the Increase circuit 20V is standard, and after that make use of the brief circuit probe to quick-circuit the RO exam level along with the 1V8 exam point between the first and the 2nd chip, then function This system to discover the chip. Examine the serial port log, if 0 chip remains identified right now, It's going to be amongst the next circumstances: a-1) Use a multimeter to measure whether or not the voltages within the 1V8 and 0V8 examination details are 1.8V or 0.8V. Otherwise, it implies the 1.8V or 0.8V LDO circuit of the area is abnormal, or the two ASIC chips of this area will not be soldered effectively; most situations of this phenomenon are attributable to shorter circuits of 0.8V, 1.8V patch filter capacitors (evaluate the resistance of the patch filter capacitors connected with the front and back with the PCBA). a-2) Look at whether the circuits of U2, U3 and U4 are abnormal, which include resistance welding, and many others. a-three) Evaluate the resistance of R232 or R233 by using a multimeter to examine whether it is within just one ohms and also the looking at won't bounce randomly. Otherwise, please substitute these two resistors. a-four) Check In the event the pins of the initial chip are soldered well (it absolutely was identified during repair that the pins are tinned observing through the side, but the pins will not be stained with tin in the least if the chip is removed). b) If 1 chip are available in step a), it suggests that the main chip plus the earlier circuit are very good. Use an identical method to examine the following chips. By way of example, quick-circuit the 1V8 examination position and also the RO check stage involving the 38th and 39th chips. In the event the log can discover 38 chips, the very first 38 chips haven't any difficulty; if you still obtain 0 chips, Check out the 1V8 first; if It can be normal, it means that there is a trouble Using the chips just after 38. Carry on to research with dichotomy until the problematic chip is identified. Assuming that there's a trouble While using the Nth chip, when the 1V8 and RO between the N-1th and Nth chips are small-circuited, N-one chips can be found, but if the 1V8 and RO involving the Nth and N+1th chips are shorter circuited, the complete chip cannot be discovered.

b) Enter the consumer identify, password and also the examination command to begin to see the NONCE return standing as well as position from the voltage domain. If there is abnormality in NONCE and area voltage, it could be repaired in accordance with the irregular chip printed.
Maintaining an Antminer S19 is often a daunting process in the event you don’t know very well what to look for. Understanding The essential measures of maintenance and troubleshooting is critical in retaining your miner functioning easily and successfully. Within this guide, We'll deal with the basics of Antminer S19 maintenance, from plan inspections to tests hash boards and replacing defective chips.
Test the welding high quality of the warmth-delicate chip as well as compact heat sink. The deformation of the massive heat sink materials will induce weak warmth dissipation in the chip and have an effect on the temperature variation.
37V. This situation is Price Here brought on by the chip not remaining soldered appropriately, usually 1.2V, 0.8V, RXT, CLK will not be soldered adequately. It is recommended to straight evaluate the area voltage to locate the problematic domain. The 1V2 and RO short circuit strategy Employed in segment a) might also Find the irregular area
When using the chassis to dissipate heat, two hashboards really should be put concurrently to variety an air duct. The only-sided examination with the generation must also make sure that the air duct is formed (essential).
● When locating the defective chip, the chip should be welded all over again. The method is to incorporate flux round the chip (if possible no-clean flux), and heat the solder joints in the chip pins to the dissolved point out to prompt the chip pins and pads to re-operate in and collect the tin, so as to realize the influence of tinning all over again. If the fault remains precisely the same just after re-soldering, you are able to immediately substitute the chip. ● The repaired hash board could be judged as a superb merchandise with in excess of two passes when testing with the hash board tester. For The 1st time, just after changing the elements, await the hash board to chill down, make use of the hash board tester to check, and after the take a look at is passed, set it apart after which great it down. For the second time, after a few minutes when the hash board cools down, exam all over again. 0 About products and solutions buy, remember to Make contact with our profits manager:
The method for repairing The problem is as follows: through the PT2 test, carefully keep track of the serial port print log. In the event the serial port has actually been working for an prolonged time period, use a brief-circuit probe to short-circuit RO and one.
S19 requirements, computing energy intake, energy offer, utilization atmosphere and various connected information are proven from the tables:
Additionally, these suggestions must also include things like instructions on cleaning components with authorised solvents like isopropyl alcohol or distilled water, as well as the best way to keep parts faraway from Extraordinary temperatures and humidity concentrations properly. At last, frequently scheduled upkeep checks ought to be carried out each and every handful of months or at the very least each year to ensure the right functioning of all parts in the technique.
