Examine the location from the temperature sensor. The temperature sensor is all Situated on the again of your PCB, though the resistance is situated around the entrance of your PCB.
Not long ago, quite a few businesses professing for being mining firms imitate us and say that they're associated with us, or that they're our department organizations, that has brought on prospects to be deceived.
(1) When the integer is claimed, it is necessary to examine whether or not the Amount change smaller board is welded effectively, and to check if the parts about the small board have Fake soldering.
Inadequate quantity of chips: If the quantity of chips is insufficient, you are able to refer to PT2 for tests and repair.
If the chip’s visual appearance isn't damaged, the chip with the lowest reaction amount in Each and every area should get replaced.
In case the miner nevertheless loses hashrate, reduce the frequency together with other conditions continue being unchanged. Permit the miner mine to find out if it is going to eliminate hashrate and whether the hash board will hit X. If it nevertheless hits X in shedding hashrate, then take away the heat sink on the hashboard for mining and await the hashrate to drop.
The subsequent fault illustrations are from Antminer 19 series mining devices, other Antminer styles are for reference only.
② Detect whether or not the circuits of U1 and U2 are irregular, including resistor in inadequate soldering, etc.;
We will also provide guidelines regarding how to use Putty software program to diagnose issues with the NONCE response position and domain voltage degrees. Using this type of information, you’ll have all the information needed to keep your Antminer S19 running at best performance.
5. In the take a look at of repairing and changing the chip, the chip ought to be analyzed to start with, after which the operate test shall be executed following passing. The function exam have to be certain that the compact heat sink is welded capable.
minerstat is not just Yet another calculator - It is a powerful mining platform that supports your copyright journey. Look Here Improve your gains, help save precious time, and improve performance with our suite of premium options:
In summary, to repair the issue, just one should really initially inspect the chip’s visual appeal and after that measure the capacitor or resistance in front of it. The difficulty is typically because of inadequate chip soldering or harm to the chip capacitor or resistor, which ends up in irregular resistance.
(one) Utilize the APW12 electric power supply (APW1212V-15V and electrical power adapter cable) to develop a take a look at System: Use thick copper wires to the positive and adverse poles of the ability provide, then link the PSU and also the hash board.
two. Once the EEPROM NG is displayed to the Liquid crystal display display in the hashboard tester, Examine whether the welding of U10 is normal;
