④ Detect whether or not the pins of the very first chip are usually not soldered thoroughly (you will discover tins over the pins from your aspect in the repair approach, but right after taking away the chip, it's uncovered that the pins are not stained with tin);
(three) Swap the one particular with a better reply as well as a person with a lower reply. Once the swap, examination the hash board again to examine if the reply from the ASIC chip is usual. If it is irregular, evaluate if the voltage On this area is reduce than the normal worth.
b) When the miner even now lowers the hash fee, then reduce the frequency to 200M, and keep other situations unchanged. Enable the miner perform mining to determine if there is a decrease in hashrate and whether or not the hash board will Exhibit X.
six. The repaired hash board should be examined having a take a look at fixture, and it must pass over two situations being judged as a good merchandise. For The very first time, immediately after replacing the add-ons, wait for the hash board to chill down, utilize the check fixture to test, and when is handed, place it on just one aspect ahead of cooling down. The second time, anticipate the hash board to cool down entirely prior to tests.
a) Liquid crystal display Exhibit ASICNG: if (0), to start with measure the full voltage on the measuring area along with the Strengthen circuit 20V is normal, and then use the limited circuit probe to brief-circuit the RO exam point along with the 1V8 exam Go Here issue involving the main and the second chip, and after that work This system to discover the chip.
● Following the plan check is passed (the small-circuit take a look at of the overall plan test is essential to stay away from the chip or other materials remaining burnt due to the limited circuit when the power is turned on), the chip exam could be executed While using the hashboard tester, plus the positioning is usually determined based on the exam result of the hashboard tester.
a) Once the LCD Exhibit ASIC NG: (0), to start with evaluate the full domain voltage of 21V plus the Improve circuit voltage of 25V when they are usual. Then use a short-circuit probe to small-circuit the RO test position and 1V2 check place involving the 1st and next chips, and then operate the chip discovering plan.
Open up MPLABIPE and choose unit: PIC16F1704, click ability to pick out the power offer manner, then click on operate. Step one: find "file" to locate the .HEX file being programmed; the 2nd move: click "hook up" to attach Typically; the 3rd action: click the "system" button, and following completion, click "verify" to prompt the verification to confirm which the programming is profitable.
① The particular Investigation technique is as follows: Very first, conduct only one-board PT2 exam to examine whether the performance of the hash board is ordinary.
(1) Unexpected electrical power failure or below 30s in the process of opening OTP will lead to the Management board to fail to open the OTP perform, as well as the Manage board will likely not get started (not connected to the Internet).

In the event the voltage price has a large deviation, Evaluate it Together with the measured price of the adjacent group to determine the issue.
S19 specifications, computing ability consumption, power offer, use environment together with other linked facts are revealed in the tables:
