When changing a fresh chip, it's important to tin the chip pins after which solder them to your hash board. Utilize thermally conductive gel evenly over the chip’s surface, then lock the heatsink.
Figure seven-5 two. Enter the person title, password and take a look at command to check the NONCE reaction status along with the position of voltage area. When the NONCE and area voltage are abnormal, user can carry out measurement and routine maintenance according to the printed irregular chip.
one. Use the 19 sequence hashboard tester SD card swiping method for The very first time to update the hashboard tester Management board FPGA, unzip it and copy it to your SD card, and after that insert the cardboard into the hashboard tester card slot; electricity on for around 1 moment and watch for the Management board indicator to double flash three periods, then the update is concluded; (if it is not updated, it could bring about a specific chip to get undesirable through the examination)
Revive your Antminer S19’s overall performance with our best-notch substitution hashboards. Expertly refurbished to make sure exceptional mining efficiency, these hashboards are your Remedy to faulty mining functions. Don’t Enable defective hashboards sluggish you down.
The voltage of each and every voltage area is about one.35V. If there is a 14V powering, there is mostly a website voltage, and the output of the facility terminal of your hash board is measured initial; when there is a 14V powering but no domain voltage, proceed to check down.
If the temperature exceeds this temperature, Inquire Now the miner will alarm and can't operate normally. Frequently, you could Check out whether or not the drinking water outlet temperature exceeds sixty five levels, and thermal conductive gel could also cause temperature abnormalities.
3. Just after repairing, the hashboard have to be tested for much more than two instances being OK in advance of it could pass!
(1) A unexpected electricity outage or lower than 30 seconds for the duration of the entire process of opening OTP will cause the Handle board to are unsuccessful to open up the OTP purpose along with the Regulate board is not going to start out (not hook up with the online world).
(two) Utilize the check fixture with the V2.1010 Command board (its product is ZJ0001000001), the constructive and detrimental poles of the facility offer in the take a look at fixture should be put in that has a discharge resistor, and it is recommended to work with a cement resistor of 25 ohms and over 100W.
Thinking about the serial port log, if 0 chip continues to be discovered at this time, Will probably be considered one of the following predicaments:
Check out if the 4 resistors of R24~R27 are welding abnormally and Verify whether or not the welding of PIN2, three of U3 is regular.
The hash board is a crucial component of a copyright mining device. If It isn't operating effectively, it can cause significant challenges. This information aims to supply troubleshooting techniques for common faults linked to the hash board.
four. To the test of chip servicing and replacement, it is necessary to detect the chip to start with, and afterwards do a functional take a look at following passing. The useful exam need to be certain that the small heat sink is soldered properly and the massive warmth sink is installed in position (Each individual thermal conductive adhesive should be used evenly just before putting in the big warmth sink).
a) Liquid crystal display Exhibit ASICNG: if (0), 1st measure the entire voltage from the measuring area plus the Improve circuit 19V is typical, and after that utilize the small-circuit probe to limited-circuit the RO test issue plus the 1V8 check point concerning the 1st and the second chip, after which you can function This system to find the chip.
