PatternNG is a dilemma that occurs due to considerable variations within the properties of a selected chip as compared to other chips. To take care of this difficulty, it's been recognized that the chip’s die is ruined and wishes to get replaced.
Get the ideal mining general performance out within your Antminer S19 by using the correct program. Be part of minerstat and locate the most suitable program in your setup.
(one) Once the integer is described, it's important to check whether or not the Stage change little board is welded perfectly, and to check whether the elements around the compact board have Bogus soldering.
3. The test SD card will be produced Based on the requirements, and the PT1 chip detection chip and PT2 perform exam will be right decompressed for making the SD card.
8. When replacing a brand new chip, clean the pins and utilize solder paste to make certain the chip is coated with tin just before soldering.
three. In the event the‘PIC sensor NG’is shown on the LCD display screen with the hashboard tester as well as the tested temperature is irregular, then follow the actions underneath to troubleshoot:
If there is no 3.3V output, Verify the connection status from the hash board tester cable and the hash board.
If your EEPROM NG is exhibited over the Liquid crystal display monitor of your hash board tester, Examine whether or not the welding of U5 is typical.
At that time, Microsoft Marketing will use your full IP tackle and person-agent string in order that it may correctly method the advertisement click and charge the advertiser.
Typical phenomena: IP can't be detected, the amount of supporters is irregular, as well as chain is irregular. If there is an abnormality inside the test, Adhere to the checking interface and take a look at LOG prompts for upkeep.
Log classification: current log, only data the current log once the miner is commenced; historical log, information the logs which the miner has produced, though the file material is proscribed, which include if it exceeds the upper Restrict, only the most up-to-date is saved.
3. After repairing, the hash board needs to be analyzed over two situations for being Okay before it can pass! 4. Check out whether the resources and hash board testers can get the job done normally, determine the maintenance station to check computer software parameters, check fixture versions, and so on. 5. While in the examination of repairing and changing the chip, the chip needs to be analyzed first, after which the functionality test shall be executed after passing. The function examination will have to make sure that the little warmth sink is welded capable. When putting in the large heat sink, the surface of the chip need to be evenly coated with thermal gel as well as the cooling enthusiast shall be at complete velocity. When using the chassis to dissipate warmth, 2 hash boards needs to be put simultaneously to form an air duct. six. When measuring the signal, use 4 fans as aid for warmth dissipation, as well as the fans shall retain total velocity. seven. When powering about the hash board, the person have to first link the destructive copper wire of the ability source, then the constructive copper wire of the facility source, and finally plug inside the sign cable. When eradicating, the order of installation need to be reversed. Initial, clear away the sign cable, then take out the good copper wire of the power offer, And at last clear away the destructive copper wire of the facility source. If the user does not follow this get, it is very easy to induce harm to R8, R9, U1, U2 (not all chips are available). Prior to tests the pattern, the repaired hash board has to be cooled down ahead of screening, in any other case, it may cause PNG tests. 8. To replace a new chip, printing pins and soldering paste are essential to ensure that the chip is pre-soldered and then soldered into the PCBA for repair. III. hash board tester building and matters needing interest The supporting fixture of the hash board tester should really satisfy the warmth dissipation from the hash board and aid the measurement of alerts. 1. Make use of the 19 collection hash board tester SD card swiping software for The 1st time to update the hash board tester Regulate board FPGA, unzip it and copy it for the SD card, then insert the cardboard to the hash board tester card slot; electric power on for about 1 minute and look ahead to the Handle board indicator to double flash three instances, then the update is concluded; (if It is far from updated, it might induce a certain chip for being bad through Look Here the take a look at). Determine three-one two. Make the take a look at SD card In keeping with the necessities, and immediately unzip the compressed offer of The one-sided warmth sink inspection chip to make the SD card; Determine 3-two three. The exam SD card will probably be designed according to the necessities, as well as double-sided warmth sink 8-times patter test needs to make an SD card, as revealed from the figure underneath;
② The second circumstance: Micro-shorter circuit involving signals (0-hundreds of ohms), brought on by the little resistor worth of the chip pins, first use a heat gun to solder and find out whether it is Alright;
Home windows mining Our mining monitoring and management software for Home windows GPU rigs is the ideal Resolution for those who prefer to mine on their Home windows equipment.
