Description
Why the Bitaxe GT — The Most Powerful Single-Board Bitaxe for Solo Bitcoin Mining
The Bitaxe GT (Gamma Turbo) is the most powerful single-board Bitaxe ever built. Two BM1370 chips — the same silicon that powers the Antminer S21 Pro — on a compact 120x60mm six-layer PCB, delivering 2.15 TH/s at just 35–43W. Designed by Skot, the original creator of the Bitaxe, the GT doubles the Gamma’s hashrate in nearly the same footprint.
- Two BM1370 chips, one board — the Bitaxe GT packs dual Antminer S21 Pro-generation ASICs onto a single 120mm x 60mm PCB. That is 2.15 TH/s of SHA-256 hashrate from a board smaller than a credit card holder.
- Best-in-class efficiency — at ~18 J/TH, the Bitaxe GT matches the efficiency of industrial mining machines costing thousands of dollars. Run it 24/7 for roughly $3.80/month in electricity at $0.12/kWh.
- 6-layer PCB engineering — the GT uses a 6-layer board with 1oz copper traces for superior heat dissipation and signal integrity. This is not a hobbyist layout — it is serious engineering in a tiny package.
- XT30 power connector — unlike single-chip Bitaxe models that run on a 5V 2.1mm barrel jack, the GT uses a 12V XT30 connector built to handle higher current reliably. The same connector trusted in high-performance RC and power applications.
- Whisper-quiet desktop operation — a 60mm Noctua NF-A6x25 fan keeps both chips cool at approximately 35 dB. Library-level quiet. Run it next to your monitor and forget it is there — until it finds a block.
The Bitaxe GT is the flagship of the single-board Bitaxe family. It doubles your solo mining odds compared to the Bitaxe Gamma, fits on any desk or shelf, and costs less to run per month than a streaming subscription. For miners who want maximum hashrate from the Bitaxe form factor, this is the top of the line.
D-Central Technologies is a pioneer in the Bitaxe ecosystem. We created the original Bitaxe Mesh Stand — the first company to manufacture it — developed custom heatsinks for the Bitaxe and Hex, and have been shipping open-source miners from Laval, Quebec since the early days of the OSMU movement. Every Bitaxe GT is inspected and tested by our ASIC repair technicians before shipping. $5–$10 from every sale goes directly to OSMU development.

Quick Setup
- Power on — Connect the 12V XT30 power supply. The Bitaxe GT boots up and creates a Wi-Fi hotspot. The OLED screen displays the device name and connection info.
- Connect and configure — Join the Bitaxe GT’s Wi-Fi hotspot from your phone or computer. The AxeOS captive portal opens automatically. Enter your home Wi-Fi network credentials, your Bitcoin wallet address, and your solo mining pool (e.g.,
solo.ckpool.orgorweb.public-pool.io). - Start mining — Save settings and the GT connects to your home network. Both BM1370 chips spin up and begin hashing. Access the full AxeOS dashboard from any browser on your network to monitor hashrate, temperatures, shares, and network stats in real time.
- Tune and forget — The GT is designed for 24/7 unattended operation. The EMC2103 thermal controller and Noctua fan manage cooling automatically. Adjust ASIC frequencies through the web dashboard if you want to push past stock speeds — or leave it at default and let it run.

Frequently Asked Questions
What is the Bitaxe GT?
The Bitaxe GT (Gamma Turbo, Model 801) is the most powerful single-board Bitaxe miner. It uses two Bitmain BM1370 ASIC chips — the same silicon in the Antminer S21 Pro — to deliver 2.0–2.15 TH/s of SHA-256 hashrate at 35–43W. Designed by Skot (the original Bitaxe creator), the GT doubles the Bitaxe Gamma’s hashrate on a compact 120x60mm six-layer PCB. It runs the open-source AxeOS firmware and connects via Wi-Fi for browser-based management.
How does the Bitaxe GT compare to the Bitaxe Gamma?
The GT has 2x BM1370 chips vs the Gamma’s 1x, delivering roughly 1.8x more hashrate (~2.15 TH/s vs ~1.2 TH/s). The key tradeoff: the GT uses a 12V XT30 power connector instead of the Gamma’s 5V 2.1mm barrel jack, and draws 35–43W vs the Gamma’s 18–20W. The GT’s 6-layer PCB provides better thermal performance than the Gamma’s 4-layer board. Both use the same BM1370 chip and AxeOS firmware — the GT simply gives you two chips instead of one.
What are my chances of finding a Bitcoin block with the Bitaxe GT?
At 2.15 TH/s against the current network hashrate (~800+ EH/s), your daily probability of finding a block is approximately 1 in 1.6 million. Over a full year of 24/7 mining, your cumulative probability is roughly 0.023%. That is nearly double the odds of a single-chip Bitaxe Gamma. The Bitaxe GT is a lottery ticket that costs approximately $3.80/month in electricity — if you hit a block, the reward is the full 3.125 BTC (~$300,000+ CAD).
What power supply does the Bitaxe GT need?
The Bitaxe GT requires a 12V DC power supply with an XT30 connector, rated for at least 10A (124W). This is different from single-chip Bitaxe models that use a 5V 2.1mm barrel jack. Do not use a 5V Bitaxe power supply on the GT — it will not work and may damage the hardware. We carry compatible XT30 power supplies in our accessories shop.
How loud is the Bitaxe GT?
The Bitaxe GT operates at approximately 35 dB — library-level quiet. The 60mm Noctua NF-A6x25 fan is one of the quietest fans in its class, running at 3000–3500 RPM. You can place it on your desk, shelf, or in your home office without noise being an issue. It is designed for 24/7 residential operation.
Can I overclock the Bitaxe GT?
Yes. The AxeOS firmware supports frequency and voltage adjustments through the web interface. Users have pushed the GT to 2.4–2.55 TH/s with overclocking. The 6-layer PCB and Noctua cooling provide solid thermal headroom. Increase frequency in small steps, monitor chip temperatures through the dashboard, and ensure your power supply can handle the increased draw. The EMC2103 thermal controller provides automatic protection.
Bitaxe GT vs NerdQAxe+ — which is better?
Both deliver roughly 2.1–2.5 TH/s, but through different architectures. The Bitaxe GT uses 2 chips (BM1370) at ~18 J/TH efficiency on a compact 120x60mm board — it is the more power-efficient and space-efficient option. The NerdQAxe+ uses 4 chips (BM1368) at ~20 J/TH, is quieter (<25 dBA vs ~35 dB), and has a larger 1.9" color LCD. Choose the GT for efficiency and compact size. Choose the NerdQAxe+ for silence and the Nerd-series ecosystem. D-Central carries both.
Which mining pool should I use?
For solo mining (the primary use case), the top choices are Solo CKPool (solo.ckpool.org) — 2% fee, proven infrastructure, 14+ confirmed block finds — and Public Pool (web.public-pool.io) — fee-free, community-driven, fully transparent. For pooled mining with regular small payouts, Ocean and Braiins are solid options. At 2.15 TH/s, solo mining lets you hunt for the full 3.125 BTC block reward.
How do I update the firmware?
Two options: (1) OTA update — open the AxeOS dashboard in your browser, navigate to Settings, and upload the latest firmware file. Takes about 60 seconds. (2) USB-C webflash — connect the GT to your computer via the USB-C port and use the Bitaxe Web Flasher at bitaxeorg.github.io for a full firmware refresh. Always use official firmware from the GitHub releases page.

Can I buy a Bitaxe GT in Canada?
Yes. D-Central Technologies is a Canadian company based in Laval, Quebec. We ship the Bitaxe GT across Canada with fast domestic shipping, CAD pricing, and bilingual support in English and French. No cross-border customs or duties. Every unit is tested by our ASIC repair technicians before shipping. Visit our shop to order.
How much electricity does the Bitaxe GT cost per month?
At 35-43W continuous draw, the Bitaxe GT costs approximately $3.80 CAD/month at $0.12/kWh (Quebec average) or $6.30 CAD/month at $0.20/kWh. That is less than a streaming subscription — and you get a shot at 3.125 BTC every single day.
Supporting Open-Source Mining
The Bitaxe GT is 100% open-source hardware and software. The PCB design is licensed under CERN-OHL-S-2.0 and the firmware under GNU GPL 3.0. Every schematic, layout file, and line of code is publicly available. You can inspect exactly what your miner is doing, verify the design yourself, and contribute improvements back to the community.
$5–$10 from every Bitaxe GT sold by D-Central goes directly to the OSMU development fund. This money supports the open-source engineers designing the next generation of decentralized mining hardware. Every sale is a vote for an open, transparent, community-driven future for Bitcoin mining.
