PatternNG is a problem that occurs as a result of significant dissimilarities in the features of a selected chip compared to other chips. To resolve this problem, it has been determined that the chip’s die is destroyed and needs to get replaced.
Examine a lot more Disclaimer: Please Observe that this details reveals only minerstat supported characteristics and might differ with the options that the particular mining components offers.
In the situation of a certain chip staying fixed, check for abnormal resistance welding of your entrance and rear CLK, CI, and BO in the Xth chip. If the check time is almost twice as long as the good board, it might reveal a difficulty with soldering.
minerstat is not just another calculator - It truly is a powerful mining System that supports your copyright journey. Enhance your gains, conserve precious time, and optimize effectiveness with our suite of quality characteristics:
8V and one.2V patch filter capacitors are small-circuited, or even the IC from the LDO circuit On this area has weak soldering/Bogus soldering/materials problems;
Or the two ASIC chips in this area are not soldered properly. A lot of them are due to quick circuit of 0.8V and one.2V patch filter capacitors (evaluate the resistance of the patch filter capacitors connected with the back and front sides of the PCBA).
Examine the instruments to make certain that the take a look at fixture can work commonly. Determine the parameters of the upkeep station take a look at program, the Edition on the examination jig, and also other similar parameters.
1. Check with the voltage price variety explained via the signal pattern. If the measurement encounters a significant deviation on the voltage worth, it might be in contrast with the measured worth of the adjacent group to determine.
① The particular Examination strategy is as follows: 1st, conduct a single-board PT2 exam to check whether the functionality on the hash board is regular.
5. During the take a look at of repairing and replacing the chip, the chip needs to be analyzed 1st, and after that the functionality test shall be executed right after passing. The functionality examination should ensure that the smaller warmth sink is welded certified.
nine. The take a look at fixtures at the upkeep finish all use the Test_Mode mode and utilize the scan code manner for tests.
Disclaimer: Please Be aware that this data displays only minerstat supported capabilities and might differ through the options that the particular mining components features. Results from mining calculator are estimation based upon The existing problem, block reward, and Trade fee for particular coin.
① The first case: (typically the value from the noted chip is not going to adjust every single exam), this case is likely to get because of abnormal soldering in the front and rear Contact Here CLK, CI, BO of your X-th chip, so give attention to these six resistors.
● Once the routine test is handed (the small-circuit take a look at of the overall regimen exam is essential to stay away from the chip or other resources currently being burnt a result of the quick circuit when the power is turned on), the chip exam is usually done With all the hash board tester, and also the positioning is usually determined based on the test result of the hash board tester. ● Based on the displayed effects in the hash board tester detection, ranging from close to defective chip, Verify the chip exam details (CO/NRST/RO/XIN/BI) and voltages which include VDD0V8 and VDD1V8. ● Based on the sign move, except for the RX signal, reversely transmit the signal (from No. seventy six to No. one chip), a number of with the alerts which includes CLK CO BO RST are ahead transmission (one-seventy six), along with the irregular fault point can be found with the ability supply sequence.
