Is my Bitaxe normal?

Just got a Bitaxe, new or used, and not sure the numbers look right? Here are the stock numbers from the Bitaxe's own firmware, board by board, and what to check first.

1. The one-minute check

Open your miner's dashboard (type its IP address into a browser on the same Wi-Fi). Look at five things:

Hashrate: use the 10-minute or 1-hour average. The live number swings a lot.
ASIC temperature: the automatic fan aims for 60°C by default.
Power: close to the seller-stated figure in the table below.
Frequency and core voltage (Settings): stock values are in the table. A used miner may have been overclocked.
Pool and fallback pool (Settings): both should be pools you chose, paying a Bitcoin address you own.

2. Stock numbers for each Bitaxe

At stock settings, a healthy board's average hashrate lands near "Expected at stock". The firmware's own self-test passes a board that reaches the pass mark.

Board	Chip	Stock settings	Expected at stock	Self-test pass mark	Seller-stated power	Power input
Bitaxe Ultra (204 / 205)	BM1366	485 MHz · 1.2 V	≈434 GH/s	369 GH/s (85%)	≈12 W	5 V
Bitaxe Supra (401 / 403)	BM1368	490 MHz · 1.17 V	≈625 GH/s	500 GH/s (80%)	≈15 W	5 V
Bitaxe Gamma (601 / 602)	BM1370	525 MHz · 1.15 V	≈1.07 TH/s	910 GH/s (85%)	≈18 W	5 V
Bitaxe Gamma Duo (650)	2x BM1370	400 MHz · 1.15 V	≈1.63 TH/s	1.39 TH/s (85%)	≈26 W	5 V
Bitaxe GT 801 (801)	2x BM1370	525 MHz · 1.15 V	≈2.14 TH/s	1.82 TH/s (85%)	≈43 W	12 V
Bitaxe Naja Duo (1201)	2x BM1373	327 MHz · 1 V	≈4.40 TH/s	3.74 TH/s (85%)	≈42 W	12 V
Bitaxe Gamma Hex (1300)	6x BM1370	690 MHz · 1.2 V	≈8.45 TH/s	7.18 TH/s (85%)	≈140 W	12 V

Stock frequency, voltage and the expected-hashrate formula (frequency × cores × chips) are from the open-source AxeOS firmware (ESP-Miner), checked Oct 28, 2026. The pass mark is the share of that number the firmware's own self-test asks for. Power is what sellers state for the model, so your reading can differ a little. Shop listings often quote higher hashrates than these because they assume a higher frequency.

3. Hashrate lower than it should be?

Wait 10 minutes and read the average, not the live number.
Check the power supply. The 600-series and older boards run on 5 V; the 801, 1201 and 1300 run on 12 V. A weak or wrong supply is a common cause of low hashrate and restarts.
Put settings back to stock (table above). Overclocks from a previous owner can make a chip unstable.
Check the fan and heatsink. Dust, a loose heatsink or dried-out thermal paste make the chip run hot and slow.
Update to the latest official AxeOS from the ESP-Miner releases page.

4. Running hot?

Around 60°C with the fan on auto is normal: that's what the fan aims for.
Above 75°C on the chip (or 105°C on the voltage regulator), AxeOS stops mining, sets the fan to 100% and shows an overheat message. Fix the cooling before you turn it back on.
Give it open air: not in a cupboard, not against a wall, not in direct sun.
A louder fan is the trade-off for a cooler chip. Lowering the frequency a little cuts both heat and noise.

5. Bought it used? Check these too

Firmware: the System page shows the version. Official AxeOS is open source; if it's a build you can't find on the releases page, reflash the official one.
Hidden fees: some modified firmware on resold miners sends part of the hashrate to someone else. Official firmware plus your own pool settings avoids this.
Pool settings: re-enter the pool, the fallback pool and your own Bitcoin address yourself.
Power supply: make sure it came with the right one (5 V or 12 V, see the table) and that it isn't a no-name brick that runs hot.

Questions

Why is my Bitaxe Gamma under 1.2 TH/s?

At stock settings (525 MHz) the firmware expects about 1.07 TH/s from a Gamma 601 or 602. Many listings quote 1.2 TH/s or more, which assumes a higher frequency. Look at the 10-minute or 1-hour average, not the live number, which jumps around.

What temperature is normal for a Bitaxe?

AxeOS's automatic fan aims for an ASIC temperature of 60°C by default, so readings around there are by design. If the ASIC goes above 75°C, or the voltage regulator above 105°C, the firmware stops mining and runs the fan at full speed.

What does the error percentage mean?

It's the share of the chip's work that came back wrong. A small number is normal. A high or rising number usually means the chip is too hot, or the voltage is too low for the frequency it's set to.

Does a higher best difficulty mean I'm closer to a block?

No. Every share is a fresh draw, so past shares don't move you closer. The solo odds page shows what your best difficulty means next to the network's.

Is a used Bitaxe worth it?

It can be, if it hits the stock numbers above, runs official open-source firmware and the price is well under a new one. Check the pool settings yourself before you trust it.
