Bitaxe Gamma
Tune for stable hashrate, not screenshot hashrate
The Bitaxe Gamma is a fun lottery miner because it is small, visible, and educational. Tuning it should be boring on purpose: raise hashrate slowly, watch heat and power, and keep the setting that survives real uptime.
Start with a baseline. Record stock frequency, voltage, average hashrate, ASIC temp, VR temp, fan speed, input voltage, uptime, accepted shares, rejected shares, and error rate.
Frequency first
Increase frequency in small steps, then wait long enough to see whether the average hashrate follows. A setting is not better if it runs hot, reboots, or creates bad shares.
Voltage second
Voltage can stabilize higher frequency, but it also raises heat and power draw. Add the smallest voltage step that makes a meaningful stability difference.
Watch the boring signals
- Hashrate average stays close to expected hashrate.
- Rejected shares stay near zero.
- Uptime does not reset.
- Fan is not pinned at 100% all day.
- Input voltage does not sag hard under load.

Download the free CSV log and record each setting before changing it again. Overnight stability is more useful than a five-minute peak.
