Be a part of the worldwide Neighborhood of miners who trust minerstat to elevate their mining game. Do you think you're prepared to unlock your mining probable?
two. For The 1st time use the 19 sequence test fixture SD card flash system to update the FPGA Regulate board in the tester, copy it towards the SD card following decompression, and insert the SD card in to the fixture card slot: Electric power on for approximately one moment, and look ahead to the crimson and inexperienced indicators within the Handle board to flash 3 times in succession, then the update is total (if It's not necessarily updated, it may well induce a fixed chip to generally be reported as faulty in the course of the test).
; secondly, after the visual inspection is handed, the impedance of each voltage domain is usually tested 1st to detect regardless of whether You will find there's shorter circuit or an open circuit. If discovered, it must be dealt with first. In addition, Check out whether the voltage of each and every area is about 0.36V.
a) LCD Screen ASICNG: if (0), initial evaluate the whole voltage on the measuring domain as well as boost circuit 20V is typical, then make use of the shorter circuit probe to quick-circuit the RO exam level along with the 1V8 exam level among the first and the 2nd chip, then work the program to find the chip. Check out the serial port log, if 0 chip is still identified presently, It's going to be one of the subsequent situations: a-one) Use a multimeter to evaluate whether the voltages at the 1V8 and 0V8 exam factors are one.8V or 0.8V. Otherwise, it suggests which the 1.8V or 0.8V LDO circuit of the domain is abnormal, or the two ASIC chips of this area is not really soldered effectively; most circumstances of the phenomenon are because of limited circuits of 0.8V, one.8V patch filter capacitors (evaluate the resistance with the patch filter capacitors associated with the back and front with the PCBA). a-2) Check out if the circuits of U2, U3 and U4 are irregular, for example resistance welding, and so forth. a-3) Evaluate the resistance of R232 or R233 with a multimeter to check whether it is in just one ohms and also the reading will never jump randomly. If not, remember to change these two resistors. a-four) Look at if the pins of the 1st chip are soldered well (it was found all through repair which the pins are tinned observing through the facet, but the pins aren't stained with tin at all once the chip is eliminated). b) If one particular chip can be found in move a), it implies that the 1st chip and also the past circuit are fantastic. Use an identical system to check the next chips. Such as, short-circuit the 1V8 check point along with the RO take a look at level in between the 38th and 39th chips. If your log can find 38 chips, the primary 38 chips have no issue; if you still obtain 0 chips, Check out the 1V8 initially; if It is really usual, this means that there is a issue with the chips right after 38. Carry on to investigate with dichotomy until eventually the problematic chip is identified. Assuming that there is a trouble Together with the Nth chip, in the event the 1V8 and RO between the N-1th and Nth chips are short-circuited, N-one chips can be found, but once the 1V8 and RO among the Nth and N+1th chips are quick circuited, all the chip can't be observed.
The voltage of every voltage domain is about one.35V. If there is a 14V powering, there is normally a website voltage, as well as the output of the ability terminal on the hash board is measured initially; if there is a 14V powering but no area voltage, go on to check down.
3. Concentrate towards the soldering procedure when changing the chip. After replacing any components, the PCB board won't be deformed. Examine the changed sections and surroundings for missing pieces, open up circuits and short circuits.
Look at the welding excellent from the chip which connects sensor as well as compact warmth sink. The deformation of enormous heat sink content will induce bad warmth dissipation in the chip and affect the temperature distinction.
The Antminer S19 is a robust miner, but its effectiveness is usually hindered by faulty hashboards. By changing them with our upgraded hashboards, you are able to make sure that your miner is usually jogging at its utmost prospective.
PS: Should the hashboard isn't run or driven off based on the exam sequence, triggering R8, R9, U1, and U2 to burn off out, the chip will report 0;
(two) U1 can not be made use of on other series of products If your OTP function is enabled to the Handle board.
① To start with, visually inspect the hash board to discover when there is any deformation or burning from the PCB. If there is any phenomenon, it should be dealt with initial.
By bringing their own personal tools, participants can learn how to take care of up to five broken products in the course of each session, generating the Contact Here vacation buy itself. Don’t Allow technological facts hold you back again.
I've experienced no concerns using this hash board since installing it in my mining tools. It operates flawlessly and delivers steady performance.
a) LCD Screen ASICNG: if (0), 1st measure the entire voltage on the measuring domain plus the Raise circuit 19V is ordinary, and afterwards utilize the shorter-circuit probe to shorter-circuit the RO exam issue as well as 1V8 check level among the initial and the second chip, and then run the program to find the chip.
