s19 hash board repair Things To Know Before You Buy

3) Try to update the flash method with SD card;When the Manage board card recovery machine must start out Commonly, the subsequent two measures are necessary:

d-1) The main circumstance: the check time is essentially the same as the good board (commonly the worth of X will likely not change every time you take a look at) (exam time refers back to the time from when the beginning take a look at button is pressed to the result of ASICNG: (X) displayed over the LCD). This situation is likely to get caused by the abnormal resistance welding in the front and rear CLK, CI, and BO of your Xth chip, so buyers shall concentrate on these six resistors. The smaller likelihood is because of X-1, X, X+1, that's, among the three chips, the next pins irregular welding situations from the chip happen: Determine 5-16 d-two) The 2nd situation: the test time is almost two times as long as the good board (from time to time the value of X will change when you test, and in some cases X=0); at this time, the log generally has the subsequent data (the pink quantity just isn't thirteen, based upon which seat the hash board tester is linked to); during the examination, believe that the area voltage of each of the fields before the irregular place is nearly under 0.

b) If the miner even now cuts down the hash rate, then reduce the frequency to 200M, and preserve other ailments unchanged. Enable the miner complete mining to discover when there is a lessen in hashrate and whether or not the hash board will Screen X.

Repair system: in the PT2 take a look at, Verify the serial port print log. If the serial port starts to operate for the long time, use a brief-circuit probe to brief-circuit RO&1.

3V, along with the area voltage of your again fields are Virtually all bigger than 0.38V. This situation is a result of the chip not being soldered effectively, commonly 1.8V, 0.8V, RXT, CLK will not be soldered perfectly. It is usually recommended to directly evaluate the domain voltage to locate which area is the problem. The 1V8 and RO short-circuit technique used in portion a) may also Identify the irregular placement;

Or The 2 ASIC chips On this area are not soldered properly. Most of them are attributable to short circuit of 0.8V and 1.2V patch filter capacitors (evaluate the resistance in the patch filter capacitors relevant to the front and back sides in the PCBA).

Popular phenomena: IP can't be detected, the volume of enthusiasts is irregular, along with the chain is abnormal. When there is an abnormality during the test, follow the checking interface and take a look at LOG prompts for maintenance.

● The repaired hashboard is often judged as a good merchandise with greater than two passes when screening with the hashboard tester. For The very first time, immediately after replacing the areas, wait for the computing board to cool down, use the hashboard tester to test, and following the take a look at is handed, established it apart and after that great it down. For the second time, right after a couple of minutes in the event the hashboard cools down, exam all over again.

minerstat is not only A further calculator - It truly is a robust mining System that supports your copyright journey. Strengthen your earnings, preserve important time, and maximize efficiency with our suite of premium functions:

Soon after replacing the components, watch for the hash board to chill down and utilize the hash board tester to check. When the examination is passed, established it aside and cool it down.
