This is one of the most common breakdowns, since all the work of mining the cryptocurrencies directly falls on the chips, which leads to breakdowns. This could be a power distribution problem, a problem with the first or last chip, or a problem requiring complete chip reflow. The hashboard needs fixing.

This is a common issue with Antminer 17 Series. It is mostly due to very poor solder quality leading to 30% failure rates on theses generations. We have noticed alot of microfracture happen especially with models T17e, S17e, T17+ and S17+. Just like the unrecognized chips, this could also be a power distribution problem or a problem with the first or last chip.

This is, again, a common problem with Antminer 17 Series. This is due to the copper plating on top of the chips which delaminate. This copper delamination is also due to the poor quality of the solder in the manufacture of these machines. Since very little TIM allows for a good heat transfer from your chips to the heatsinks, the copper plating peels off from the top of the chip and the heatsinks follow. Your machine cannot mine even if only one heatsink is missing. There are two solutions available, either a repair that requires replacing all the chips delaminated from your hashboard, or a replacement of the original heatsinks for our upgraded all-in-one heatsink, which completely protects you from this problem in the future.

Any hashboard or units containing traces of burns are automatically disqualified from our repairs. In almost no case these can be rescued or very rarely in a profitable manner. We also disqualify from our repairs any 17-series hashboard that has silicon to hold its heatsinks or any form of glue that prevents the signal from being detected. There is a large volume of machines bought in China which contains only glue or silicon and which burns your chips within hours of use. We advise you to get reimbursment from the sellers of these machines which are nothing short of scams.

Machines which have several delaminated chips/heatsinks missing or which need replacement of more than 5 chips are disqualified on a case by case basis, depending on the level of difficulty and the cost of the repair, it may happen that we will tolerate such a repair, it will however be longer and not be a priority.

For the equipment to work as long as possible, it is necessary on time to:
• blow fans;
• assess the operation of the cooling system;
• check the effectiveness of cooling systems;
• blow heatsinks;
• track the operation of chips and the possibility of overheating.

One or more of your temperature sensors need to be replaced. In some cases, it may also be chips around the temperature sensor that are not passing the correct values ​​and may require chip replacement. You can send your hashboard to our repair center where we will quickly replace your sensors, test all chips, and return your board ready for hashing.

Yes, absolutely! Our Innosilicon A10 upgrade service from 4G to 5G or 6G is one of our most popular services. This is explained by the high valuation of these machines thanks to their monster profitability of the moment. This is a tough and long task and requires between 24 to 48 parts replacement.

First of all, the prices vary between them according to the level of difficulty of a repair, the number of points of failure and our experience with models that are more problematic than others. Second, the prices of the parts themselves are bound to have a direct impact on our pricing since we include the replacement of 5 parts on each repaired hashboard. If you have say 5 boards under repair with us, rest assured, the set of 25 chips is interchangeable between your hashboards under repair. This is why our prices can also vary over time, if a shortage of chips is felt as it is now, the prices of parts unfortunately increase, making the repair more expensive.

We currently have lead times of around 1 to 3 months. This is explained by the rise in prices, the high failure rates of the 17th generation of Bitmain, the strong demand for upgrades from A10 as well as all the measures relating to COVID 19. Indeed, our center for repair is currently running at maximum legal capacity. We are striving to continue to grow very quickly, with a list of clients growing day by day. Thank you to all for your confidence and your understanding.
