What do you need to prepare for overclocking crypto miners? You need a new board, higher power supply up to 4500W, 6000W, and 8000W which are professional overclocking solutions and your anterminer S19 95t, 104t,or 110T. Meanwhile including an immersion cooling system. Below are details of different overclocking PSUs for different hash rate for your reference. 8000W Overclocking Power Supplyfor S19pro 110T overclock  to 180T+/ immersion cooling 6000W Overclocking Power Supplyfor S19pro 110T overclock to 150T+/ immersion cooling 4500W Overclocking Power Supplyfor S19pro 110T overclock to 130T+ / fan cooling Three kinds of Overclocking Boards board 1:  for S19pro 110T overclock to 150T+ by oil coolingboard 2:  for S19pro 110T overclock to 130T+ by fan coolingboard 3:  for S19 95T overclock to 110T+ by fan cooling When you prepared well for those, then you can start assembling the board and remove the old PSU with the overclocking PSU.below video for your reference. After finishing reassemble the board and PSU, then put the miner into the oil immersion cooling system. Hope those information makes your crypto mining business more profitable.

Replace the control board for your ASIC miner is very simple, just follow below steps and you will also be a repair engineer. ( Put on gloves on your hands will be safer.) 1. Remove the ASIC Fans from the miner , took off the fan cable from the control board. 2. Remove the cable between control board and hash board. 3. Take out the hashboard and clean the board, make sure the heat sink stick well on the hash board. 4. Take out the broken control board and replace the new board, make sure the led light and plan ports fits well with the miner shell. 5. Connect all the cables well and assemble the fans well. If All done well and connect the power to test the miner. The below video shows one of the professional Computer engineer’s operations for your reference. If you have any questions for repair miners parts, please feel free to contact us. We will guide you online for free. Whatsapp 86 13728685427, Email 1@sz-sinowell.com

Antminer Power supply Common Troubleshooting Fan don’t work, no 12V output Reason:The power supply on the AC side  is abnormal Ways to deal with 1.Check the AC side if the connector connect tightly 2.Check whether the grid has power and the voltage is normal Fan work normally, no 12V Output Reason: 1.low grid voltage ,2.power protection Ways to deal with 1.Use a multimeter to confirm that the current voltage is above 250V, so as to ensure that the power supply can be turned on 100% 2.Check if the power supply has output or overload. This situation will cause the power supply to enter the lock-up protection state. It can be restored after removing the fault and restarting the power supply. After the power supply stops outputting for a few seconds, it resumes normal working, and continues to work for a few minutes and then stops outputting, trouble happens repeatedly Reason: The power supply has entered the over-temperature protection Ways to deal with 1.Check if the fan work normally2.Check whether the cooling air channel of the power supply is blocked3.Check whether the power supply has been used for a long time and there is too much dust accumulated inside4.Check the voltage used by the power supply or the surrounding temperature exceeds the value of the power supply power setting curve Miner output normally, but fan didn’t work Reson: Fan broken Ways to deal with 1.Check if the fan is blocked by other things2.fan is broken A normally working power supply suddenly

During the process of shipping for those heavy ASIC Miners, there will be some damage to miners, like problems with Fans/PSU/Hash boards/Control boards because international logistics would not take good care of the heavy items. Meanwhile, the miner will stop working after working for a long time. For Hash boards and Control boards, we could support free repairs if you don’t mind affording the Round-trip shipping. For Used miners, we strongly suggest that it’d purchase extra spare parts like Fans/PSU as preparation for exchanges because they usually get damaged during the long trip shipping easily. We offer full series of ASIC Miner’s parts, like Antminers Parts, Whatsminer Parts, Avalon Parts, Innosilicon Parts, and Goldshell KD Box parts. Among those parts, we have basic chips, hash board, fans, power supply, power cord cable, capacitor, control board. Regarding to the repair tools, We have Antminer test fixture, Tin tool sets, hash board code editor, universal chip fixture , Portable desoldering gun, Headband Magnifier,oscilloscope, Electronic magnifier, ANLIXIN-862D desoldering station,205H high-frequency soldering station, DDR5 DDR5X DDR6 combination Tin Tools, etc. We also offer programs like L3+ Tester Production File, universal Antminer test fixture TF card programs, and Antminer hash board PIC file. If you have mining farm, we can offer you Combined shelf, Negative pressure fan, Power socket module, Mobile miner box, ASIC miner external water cooling radiator fan, Miner water cooling water pump.

It is not easy to read and can make bookkeeping a little annoying, but it allows Bitcoin transactions to be tracked across the network, which is important given the Bitcoin mantra of transparency and immutability. By using this system, people can trace every Bitcoin transaction back to the origin of the currency, with the understanding that anyone can send a Bitcoin to anyone at any time. By routing transactions through banks and other financial service providers, each transaction is validated by each node in the Bitcoin network and recorded on a secure blockchain.     Once approved, the transaction will be merged with other transactions to form a block that will be added to the ever-growing transaction chain. The transaction data is then sent via a decentralized network of Bitcoin nodes.   Once completed the block is encrypted and the transaction log is permanent; it cannot be removed from the blockchain or altered. The blockchain is public, which means that anyone who owns the blockchain can view the transaction logs.   Public blockchains allow users (who need computing power) to participate in the authorization and recording of transactions on the blockchain via nodes. Each node has its own copy of the Bitcoin blockchain, and when the network approves or dismantles a block, it is updated, trusted, and verified. Network nodes validate transactions and add them to their copies of the blockchain, which are then broadcast and added to other nodes.     Bitcoin transactions make the existing public register accessible to everyone, making transactions harder to
