What is the safest way to update ASIC firmware?

Verify the exact model and control board, download from official sources, back up settings, and update on a stable power and network connection.

What should I check before flashing?

Confirm firmware compatibility, read release notes, and prepare a rollback plan to stock firmware. Avoid files from unofficial mirrors.

Why does control board compatibility matter?

A mismatched control board is a common cause of failed flashes and boot loops. Always match the firmware to the correct board revision.

How can I reduce the risk of bricking a miner?

Do one change at a time, avoid power loss during flashing, and keep recovery media (SD image / rescue instructions) ready for the exact model.

Are custom firmware gains worth it?

Custom firmware can improve efficiency or add features, but results depend on model, cooling and silicon quality. Start with conservative profiles and monitor stability.

What autotune does

Autotune attempts to find stable frequency/voltage combinations based on your chips’ real characteristics.

It can improve efficiency (hash/W) and reduce manual trial‑and‑error.

Autotune needs time — don’t judge results after 5 minutes.
Always start from a conservative power cap.

Profiles: efficiency, balanced, performance

Profiles bundle settings that target different outcomes: lowest watts, stable default, or higher hashrate.

If your electricity price is high, efficiency usually wins.

Efficiency profile first → verify stability → then consider balanced/performance.
Keep fans/temps under control — heat kills margins and hardware.

Practical safety tips

Use vendor docs for your exact model and control board.

If the miner becomes unstable, revert to a known‑good profile or stock firmware.

Tune one miner first, then scale out.
Log “before/after” watts and pool hashrate for ROI decisions.

FAQ

Can autotune damage hardware?

Bad settings or insufficient cooling can increase stress. Use conservative limits and monitor temperatures.

Why does autotune take long?

It tests many combinations and needs stable operating conditions.

Do all miners support autotune?

No. Support depends on firmware vendor and model/control board.
