Should the relationship is OK, you may execute a PT2 take a look at on the board to see if it may move the take a look at. If it can be analyzed, it is basically selected that it is a dilemma with the Management board. If it can't be tested, use a similar repair process as PT2 to repair it.

In the event the check chip is just not completely detected, the board must be repaired. If it is usual following the test, take out the hash board individually, utilize the check fixture to hold it in to the Debug master system to mine, and adjust the supporter velocity to 95%.

In the event the faulty chip is situated, weld the chip yet again by including flux round the chip and heating the solder joints from the chip pins into a dissolved point out. This could prompt the chip pins and pads to re-operate in and gather the tin, obtaining the effect of tinning once again.

● Once the routine check is handed (the small-circuit check of the overall schedule take a look at is essential to stay away from the chip or other materials currently being burnt as a result of small circuit when the facility is turned on), the chip take a look at is often done with the hashboard tester, as well as the positioning is usually determined in accordance with the test result of the hashboard tester.

8. When replacing a fresh chip, clean up the pins and apply solder paste making sure that the chip is coated with tin prior to soldering.

Get the top mining effectiveness out of the Antminer S19 XP by using the correct program. Sign up for minerstat and discover the most fitted software package for your setup.

Verify the welding top quality in the chip which connects sensor plus the smaller heat sink. The deformation of huge heat sink material will cause weak warmth dissipation from the chip and have an affect on the temperature change.

(1) A sudden electric power outage or below thirty seconds throughout the process of opening OTP will bring about the Manage board to fall short to open up the OTP functionality as well as the Regulate board will never start (not connect to the online world).

Continue on to investigate with dichotomy until the problematic chip is found. Assuming that there is a issue Using the Nth chip, if the 1V8 and RO among the N-1th and Nth chips are short-circuited, N-1 chips can be found, but once the 1V8 and RO involving the Nth and N+1th chips are quick circuited, the entire chip cannot be identified.

Frequent phenomena: IP cannot be detected, the number of admirers is abnormal, and also the chain is irregular. When there is an abnormality inside the test, Keep to the monitoring interface and exam LOG prompts for upkeep.

Should the short-circuit is still present, you could unplug the CPU and evaluate once again. Other voltage abnormalities generally change the corresponding voltage converter IC.

Our replacement hashboards are not merely refurbished, They are really upgraded to guarantee improved general performance and dependability than the original. Each individual hashboard goes by way of a demanding Restoration approach that makes them additional trusted than new ones straight within the producer.

a-three) Evaluate the resistance of R8 or R9 with a multimeter to check if it is inside 10 ohms as well as the looking at will not jump randomly. If not, please change these two resistors. a-4) Examine In case the pins of the 1st chip are usually not soldered effectively (it had been located in repair which the pins are tinned observing within the facet, although the pins aren't stained with tin in the slightest degree in the event the chip is taken off). b) If one particular chip can Antminer s19 Pro Hashboard be found in move a), it indicates that the very first chip and also the previous circuit are superior. Use a similar technique to examine the following chips. By way of example, shorter-circuit the 1V8 test level as well as the RO test position in between the 38th and 39th chips. If the log can discover 38 chips, the main 38 chips have no challenge; if you continue to uncover 0 chips, check the 1V8 initial; if It is really typical, this means that there's a issue Together with the chip following 38. Keep on to analyze with dichotomy till the problematic chip is located. Assuming that there's a trouble Together with the Nth chip, if the 1V8 and RO concerning the N-1th and Nth chips are short-circuited, N-one chips can be found, but when the 1V8 and RO amongst the Nth and N+1th chips are small circuited, your complete chip can not be located.

Continue on to investigate with dichotomy until the problematic chip is observed. Assuming that there is a challenge with the Nth chip, when the 1V8 and RO involving the N-1th and Nth chips are brief-circuited, N-one chips are available, but when the 1V8 and RO amongst the Nth and N+1th chips are brief circuited, all the chip can not be identified.
