Step-by-Step Installation Guide

This guide shows you step by step how to mount the Copperzilla on your Bitaxe yourself.

The guide for setting up the Bitaxe is available here.

Congratulations on your Copperzilla 2.0

Do not touch the copper heatsink with bare hands. The fine film of grease on your skin leaves permanent stains on the copper.
Only handle it by the fan or wear gloves.

Take off Heatsink

1. Remove the old heatsink

  • Carefully disconnect the fan cable from the pins.
  • Carefully unscrew the 4 screws that go through the Bitaxe from the back.
  • Carefully lift the heatsink off the miner.
  • Carefully and thoroughly clean the ASIC chip with a suitable cleaning cloth.

2. Check the contents

Check that your Copperzilla kit is complete. The box contains the following parts:

  • 1x assembled Copperzilla incl. fan
  • 4x spacers
  • 4x hex nuts
  • 1x mounting plate
  • 1x hex screw head
  • thermal paste incl. cleaning cloth, if included

You also need your Bitaxe.

Check if the screws are tightned

3. Preparation

Check that the 4 screws of the Copperzilla are fully screwed in and have not come loose during transport.

Apply Thermal paste to the ASIC Chip

4. Apply thermal paste

Apply a lentil-sized dab of thermal paste to the center of the ASIC chip.

5. Place the miner

Before you connect the Copperzilla to the miner, be sure to remove the protective film from the contact surface.
Make sure the curved heat pipes face up and the fan cable faces down.
Then carefully place the miner upside down on the heatsink. The chip should now lie flat on the contact surface.

6. Screw it together

  • Place the 4 spacers on the 4 screws.
  • Place the mounting plate on the spacers.
  • Place the 4 hex nuts on the screws.

Tighten the nuts with the supplied hex screw head carefully and only hand-tight (no more than 1 to 2 Nm).

Do not overtighten, otherwise the ASIC may be damaged.

Fan gets plugged in

7. Connect the fan

Now carefully plug the fan cable onto the pins at the bottom end of the mainboard.

Then push the fan all the way up towards the display so that it protrudes slightly. This adds a little performance, because the voltage regulator is then passively cooled as well.

8. Adjust the settings

Because the chip now stays much cooler, you can raise the frequency in your AxeOS dashboard and generate more hashes per second.
Our recommendation:

Silent mode: 750 MHz / 1200 mV, about 1.5 TH/s
Very quiet fan, about 50% more hashrate than a typical Bitaxe with stock cooling.

Performance mode: 1000 MHz / 1300 mV, about 2 TH/s
2 TH/s on a single Bitaxe.
