10. Should the nonces of most chips in the entire miner or single board are returned to 0, it will likely be a chip welding trouble. Reinstall it and it will be OK.
(three) Swap the 1 with the next reply along with the just one by using a lessen reply. Following the swap, check the hash board again to check whether or not the reply of the ASIC chip is ordinary. If it is irregular, evaluate if the voltage Within this domain is decreased than the normal value.
(two) In the event the chip continue to reports an integer selection following confirming the little board, initial Test whether the RX signal is ordinary, and in addition evaluate whether or not the chip details one.
● After the regimen test is passed (the shorter-circuit check of the final schedule test is important to avoid the chip or other products becoming burnt due to quick circuit when the ability is turned on), the chip exam might be carried out Using the hashboard tester, and the positioning may be determined according to the check result of the hashboard tester.
three. If your PIC sensor NG is exhibited on the Liquid crystal display monitor on the hash board tester as well as the take a look at read through temperature is irregular, then follow the ways beneath to troubleshoot: A) Test if the four resistors of R24~R27 are welding abnormally, and Look at if the welding of PIN2, three of U3 is ordinary; Figure 5-13 B) Test whether or not the 4 temperature senses U4, R28~R30, U6, R31~R33, U7, R34~R36, U8, R37~R39 as well as the matching resistance welding are abnormal, The placement of the temperature sense is shown in Figure 5-14, the temperature sense is all Situated about the back in Look Here the PCB, the resistance is found to the entrance in the PCB, and whether the temperature-sensitive 3.3V electrical power provide is usual;
(2) If the looks in the chip is just not ruined, just change the chip with the bottom response rate in Every single area;
three. Right after repairing, the hashboard has to be tested for in excess of two occasions for being Alright prior to it may possibly pass!
② Detect whether or not the circuits of U1 and U2 are irregular, including resistor in weak soldering, etc.;

When you click on a Microsoft-furnished advert, you will end up redirected on the advertiser’s landing page by means of Microsoft Advertising’s platform.
five. While in the check of repairing and changing the chip, the chip has to be examined initial, after which you can the operate test shall be carried out after passing. The purpose test will have to be sure that the little heat sink is welded qualified.
Through testing, it really is assumed that the domain voltages of all domains in front of the irregular site are Nearly all under 0.3V, although the area voltages of the next domains are Practically all better than 0.
Remember to be cautious not to imagine any impostors, remember to Check out our proper Get hold of information and Watch out for remaining deceived obtaining scammed, and getting rid of cash. please Look at our suitable Speak to way: Right here
Repair system: Verify the looks, measure the chip capacitor or resistor in entrance, it is often due to bad soldering with the chip or even a harmed chip capacitor or resistor or abnormal resistance price;
