Fine Tuning the Bitaxe Settings

Why is any fine-tuning needed?

  • Every Bitaxe contains a single ASIC chip. Because of tiny manufacturing tolerances, chips vary slightly in efficiency and heat output—often called the silicon lottery.
  • We ship your miner with a deliberately high clock (636 MHz) and moderate undervolting (1125 mV). For the vast majority of chips this gives the best blend of high hashrate and great efficiency straight out of the box.
  • A few chips are more “temperamental”. They need a one-time voltage tweak so the fan doesn’t have to run at full speed all the time.

Quick health check

  • Power the miner and let it run for 5–10 minutes.
  • Open the web dashboard and watch the numbers:
  • The firmware’s Automatic Fan Control locks onto an ASIC target temperature of 60°C.
  • If your Bitaxe cannot reach 60°C while the fan sits at 100 %, the chip simply wants a bit less core voltage.

Fine-tuning in three small steps

  • Step 1 – Drop voltage one notch
    • Set the Core Voltage to 1100 mV in the Settings.
    • Wait 5 minutes and check whether the temp settles at 60°C and the fan backs off below 100 %.
  • Step 2 – Still too hot or loud?
    • Lower once more to 1060 mV and test again.
  • Step 3 – Counter-check for over-throttling
    • If hashrate falls sharply (below ~1.00 TH/s), you went too low.
    • Raise the voltage one step until stability and performance return.

(Selectable steps: 1060 mV → 1100 mV → factory default 1125 mV.)

Stress-free hashing cheat-sheet

  • Look first, tweak second: confirm temps before touching voltage.
  • Change one step at a time and watch the miner for a few minutes.
  • The sweet spot is reached when:
    • the ASIC hovers steadily at 60°C,
    • the fan isn’t pinned at 100 %,
    • hashrate is around 1.30 TH/s.

 

With this small “handshake” between you and your unique chip, your Bitaxe will run cool, quiet, and maximally efficient for the long haul. Good luck & happy hashing! ⚡️
