If the link is OK, the consumer can test the single board PT2 to examine if it could possibly pass the take a look at. If it passes the test, it could possibly mainly be determined that the condition is to the Management board. In the event the test fails, utilize the PT2 repair approach to repair it.
(3) Swap the just one with a higher reply and also the one particular using a lower reply. Following the swap, exam the hash board all over again to examine whether or not the reply of your ASIC chip is standard. If it is irregular, evaluate if the voltage With this area is reduce than the normal price.
Prior to screening the pattern, the repaired hashboard have to interesting down right before testing; otherwise, it'll cause tests NG.
Repair process: through the PT2 take a look at, Verify the serial port print log. In the event the serial port begins to work for a long time, use a short-circuit probe to limited-circuit RO&one.
To the Liquid crystal display Screen ASIC75, small-circuit the 1V8 exam position and also the RO test position among the 38th and 39th chips. If quick-circuiting forty seven chips, although the log stories forty six, it signifies which the 47th chip can not be detected, as well as 47th chip ought to get replaced.
Don’t Enable faulty hashboards have an affect on your mining efficiency. Upgrade your Antminer S19 with our reliable and high-undertaking alternative hashboards nowadays.
Our alternative hashboards are not simply refurbished, These are Inquire Now upgraded to make certain improved performance and reliability than the first. Each and every hashboard goes by way of a demanding recovery procedure which makes them much more reliable than new kinds straight from your company.
(one) Sudden electrical power failure throughout OTP or time of a lot less than 30s will trigger the Management board to fail to open the OTP perform.
The supporting fixture of the hashboard tester ought to fulfill the warmth dissipation in the hashboard and aid the measurement of indicators.
For those who have any dissatisfaction throughout the transaction or have useful tips for us, please Get hold of us by means of this e mail handle:
d-1) The main case: the test time is largely similar to the good board (generally the worth of X will never modify each time you test) (take a look at time refers to the time from when the beginning take a look at button is pressed to the results of ASICNG: (X) displayed on the LCD).
3. The exam SD card are going to be manufactured Based on the necessities, as well as the double-sided warmth sink eight-moments Patter test ought to make an SD card, as shown while in the determine underneath;
① The primary scenario: (normally the worth of your reported chip will never improve each check), this circumstance is likely to generally be brought on by abnormal soldering from the front and rear CLK, CI, BO on the X-th chip, so give attention to these 6 resistors.
The voltage of every voltage area is about 0.36V. When there is 14V electric power supply, commonly it has domain voltage. The priority is specified to measure the output of the facility supply terminal in the hashboard and whether or not the MOS is brief-circuited (evaluate the resistance among pins 1, four and eight). If 14V has ability provide but no domain voltage, keep on to examine.
