L3+ – L3+ hashrate is low or a hashboard is faulty

The first step to follow when your ASIC seems faulty is to do a “factory reset” of the machine. You can do this using the interface option, but it is recommended to overwrite the NAND using a MicroSD card. You can download firmware from our website download section: https://d-central.tech/downloads/firmwares/

Let the ASIC miner age for about 30 minutes after reflashing the firmware.

If that doesn’t solve your problem, try to identify the faulty component. Switch the controller cable between hashboards. If the same hashboard shows the problem, then the hashboard is defective. If the problem follows the cable, either the controller or the cable may be faulty.

If still not resolved, please test each hashboard separately to determine which hashboard failed. You can do this by keeping the power connector of one hash board connected to the cable of the control board and disconnecting the cables of the other two hash boards. With the miner’s operation, you can see the status of the connected hashboard.

If you have a tester like the ARC or PicoBT, you can also test hashboards individually using those and a lab power supply.
