one. Utilize the 19 collection hashboard tester SD card reflash application for The 1st time to update the hashboard tester Command board FPGA, unzip it and replica it to the SD card, and after that insert the cardboard into your hashboard tester card slot; electrical power on for around 1 moment and wait for the Regulate board indicator to double flash three moments, then the update is accomplished; (if it is not current, it could induce a particular chip to report fault through the check)
(three) Swap the 1 with an increased reply plus the one having a lessen reply. After the swap, exam the hash board once again to examine if the reply with the ASIC chip is typical. Whether it is abnormal, measure if the voltage During this area is decrease than the normal worth.
8V, 1.8V patch filter capacitors (evaluate the resistance of the patch filter capacitors connected to the back and front in the PCBA)
Revive your Antminer S19’s performance with our top rated-notch substitute hashboards. Expertly refurbished to ensure optimum mining performance, these hashboards are your Remedy to defective mining functions. Don’t Permit defective hashboards sluggish you down.
Join the global Group of miners who belief minerstat to elevate their mining video game. Have you been willing to unlock your mining opportunity?
Disclaimer: Be sure to Be aware this info shows only minerstat supported options and may possibly vary from the features that the actual mining hardware gives. Success from mining calculator are estimation based on The present problem, block reward, and Trade price for unique coin.
2. Make the SD tests card In keeping with the requirements, and instantly unzip the compressed package deal of the single-sided warmth sink inspection chip to generate the SD card;
② Detect if the circuits of U1 and U2 are abnormal, for instance resistor in lousy soldering, and so on.;
Get the most beneficial mining general performance out within your Antminer S19 by utilizing the suitable application. Join minerstat and discover the most fitted software package on your set up.
If the chip isn't observed, check for doable difficulties like irregular voltage with the 1V8 and 0V8 test details, troubles With all the U1 and U2 circuits, resistance of R8 or R9, and if the pins of the very first chip are soldered nicely.
If the massive heat sink product is deformed, it may cause poor heat dissipation of the chip and have an impact on the temperature variance.
three. Right after repairing, the hash board must be examined much more than two moments to generally be Okay just before it can pass! 4. Verify if the applications and hash board testers can perform normally, determine the upkeep station to check computer software parameters, take a look at fixture variations, etc. 5. Inside the examination of repairing and replacing the chip, the chip ought to be examined initially, and then the function test shall be performed soon after passing. The purpose take a look at ought to make sure the compact heat sink is welded qualified. When setting up the big heat sink, the area in the chip has to be evenly coated with thermal gel and also the cooling fan shall be at entire speed. When utilizing the chassis to dissipate warmth, 2 hash boards needs to be placed simultaneously to sort an air duct. six. When measuring the signal, use four enthusiasts as help for warmth dissipation, along with the supporters shall maintain whole speed. seven. When powering on the hash board, the consumer must initially join the unfavorable copper wire of the facility offer, then the favourable copper wire of the facility source, and finally plug during the sign cable. When eliminating, the buy of installation needs to be reversed. Go Here Initial, clear away the sign cable, then take out the optimistic copper wire of the ability offer, And at last take away the damaging copper wire of the ability provide. If the person does not adhere to this buy, it is vitally straightforward to trigger harm to R8, R9, U1, U2 (not all chips are available). Ahead of screening the pattern, the repaired hash board has to be cooled down just before tests, otherwise, it may well bring about PNG screening. 8. To exchange a different chip, printing pins and soldering paste are essential to ensure that the chip is pre-soldered after which you can soldered for the PCBA for repair. III. hash board tester earning and matters needing interest The supporting fixture of the hash board tester should really fulfill the warmth dissipation in the hash board and aid the measurement of indicators. one. Use the 19 collection hash board tester SD card swiping application for The very first time to update the hash board tester control board FPGA, unzip it and duplicate it into the SD card, and afterwards insert the card to the hash board tester card slot; energy on for around 1 minute and watch for the Command board indicator to double flash 3 times, then the update is completed; (if It's not necessarily updated, it might bring about a certain chip to become terrible throughout the examination). Determine three-1 2. Make the examination SD card Based on the necessities, and straight unzip the compressed bundle of The only-sided heat sink inspection chip to generate the SD card; Determine three-2 3. The check SD card will be built Based on the requirements, and the double-sided heat sink eight-periods patter exam really should make an SD card, as demonstrated within the figure under;
I was upset While using the performance of this hash board. It absolutely was slower than other choices I had tried using, and did not produce precisely the same amount of hashing ability.
1. Listen for the Procedure approach when changing the chip. After changing any accessories, the PCB board shall don't have any noticeable deformation. Examine the substitute parts as well as surrounding areas for open up circuit and short circuit concerns.
