Hilfe & Support

Connect the power supply, then join the device’s own Wi-Fi (Bitaxe_XXXX, NERDAXE_XXXX or NerdQAxe_XXXX) and open http://192.168.4.1. Enter your 2.4 GHz Wi-Fi there; afterwards in AxeOS under Pool Settings: stratum host pool.opensourceminers.de, port 3333, stratum user = your Bitcoin address, password x – ready-made values in the pool configurator. The step-by-step guides with pictures are above.

First check that your Wi-Fi password is correct. Make sure you are using a stable 2.4 GHz network and that the Bitaxe has decent reception. It is best to set the device up near your router first. If the connection still fails, restart the Bitaxe and repeat the setup.

In most cases the pool configuration is incomplete or incorrect. Check that pool URL, worker name, wallet address and any other credentials are entered correctly – the pool configurator provides the right values. Also check that there is an active internet connection and that the power supply is stable. The troubleshooter takes you to the cause in three clicks.

The hash rate is extrapolated from shares and therefore swings by ±30 % in the short term – what counts is the hourly average compared with the “expected” value in AxeOS. A hash rate error up to 5 % is normal; persistently above 10 % means too little voltage for the clock, heat (ASIC above 65 °C) or a power supply at its limit (input voltage below 4.8 V). The order to check: hash rate error explained and the troubleshooter.

The one in the box: Bitaxe Gamma, Copperzilla and Nerdaxe Gamma run on 5 V / 6 A (30 W), the Nerdaxe Gaia on 12 V / 6 A, the Bitaxe GT on 12 V / 5 A, Bitaxe 702 and the NerdQaxe models on 12 V / 10 A, NerdQX and NerdOctaxe on 12 V / 20 A. A supply that is too weak does not show up at power-on but as restarts under load – in AxeOS the input voltage on 5 V devices must not drop below 4.8 V. More in the power supply guide.

Yes, mining produces heat, which is why good ventilation and enough distance to other devices matter. Keep the vents clear and do not run the device in enclosed or very warm environments. As a guide: ASIC temperature under 65 °C is fine; from 70 °C the AxeOS overheat protection throttles the miner. For quieter and cooler operation see making a Bitaxe quieter.

Fastest through our web flasher: pick the device, plug in the USB-C cable, click “Install firmware”. As long as “Keep configuration” is ticked, Wi-Fi, pool and Bitcoin address survive the update. The flasher pulls the firmware straight from the official releases and only allows the image that belongs to your model – you cannot pick the wrong one. What an update brings and what to check first is in the AxeOS update guide.

First check the power supply, the cable and the connector. If possible, test another compatible power supply or cable. If the device still does not start, please contact us with your order number and a short description of the fault.

Start with the troubleshooter: it narrows down the most common faults and hands your click path straight to the contact form. If that does not help, send us a short description of the problem by email or Telegram. Photos or a short video help if the fault is visible. We will then go through the next steps with you and help with diagnosis or, if necessary, with a warranty claim.

Everything about withdrawal, returns and warranty claims is on our page right of withdrawal & returns. Please contact us before sending anything back so that we can give you the correct return address – that way your return is processed faster and assigned correctly.
