The open-source solo mining community moves fast. Just months after the Bitaxe Gamma 601 redefined desktop mining with the BM1370 ASIC chip, the hardware ecosystem is already taking its next massive leap forward.
If you have been following the solo mining scene, you know that the debate of Bitaxe 601 vs 602 is the hottest topic in hardware forums. But the 602 isn’t just a minor cosmetic update—it represents a complete reimagining of thermal limits and power delivery.
At DigLucky, we have officially launched the mass production of the Bitaxe Gamma 602. In this technical deep dive, we will map out the engineering journey from the original 1.2T baseline , explain how we now achieve a stable 1.7 TH/s on the 602 at a competitive factory price, and reveal the hardware breakthroughs that allowed us to unlock this unprecedented performance as of May 2026.
⚡ Quick Answer: The Bitaxe 601 vs 602 Roadmap
Understanding the upgrade path from the Gamma 601 to the 602 is simple:
- The Baseline (Bitaxe 601): Shipped with a standard heatsink. Factory default was 1.2T. Pushing it to 1.5T caused excessive fan noise and thermal throttling.
- The Present (Bitaxe 602 – Available Now): Upgraded with a high-density pin-fin heatsink. Currently ships at a stable 1.5T with library-level silence. Crucial detail: It costs exactly the same as the 601.
- The Reality (Bitaxe 602 – 2026 Update): Having successfully resolved the thermal bottlenecks of previous designs, DigLucky has finalized all power-delivery optimizations. As of May 2026, all mass-produced Gamma 602 units ship with a factory-verified, stable hashrate of 1.7 TH/s as the standard default.
Phase 1: The Bitaxe Gamma 601 Era (1.2T to 1.5T)
When the Bitaxe Gamma 601 was introduced, it was a revolution. Utilizing a single BM1370 ASIC chip (the same silicon found in the Antminer S21 Pro), it easily achieved 1.2 TH/s at roughly 18 Watts.
However, geeks always want more. At DigLucky, our engineers began pushing the frequency and core voltage (Vcore) in AxeOS to see what the silicon could handle. We successfully achieved 1.5 TH/s on the 601.
The Bottleneck: While the chip could handle 1.5T, the physical hardware of the 601 could not. The standard extruded aluminum heatsink became completely saturated with heat. To keep the chip from entering the “thermal throttle” zone (>70°C), the 40mm fan had to run at maximum RPM, turning a quiet desktop miner into a noisy distraction.
We realized that to make high hashrates viable for residential users, the physical cooler had to evolve.
Phase 2: The Bitaxe Gamma 602 Revolution (1.5T, Zero Price Increase)
Enter the Bitaxe Gamma 602. The core PCB architecture remains largely identical to the 601, but the physical thermal module has been completely overhauled.
The 602 features a custom-machined, high-density black anodized pin-fin heatsink. This design exponentially increases the surface area exposed to airflow.
The Current State of the 602:
- Stable 1.5 TH/s: Because heat is dissipated so efficiently, the 602 runs at 1.5T effortlessly without aggressive thermal throttling.
- Whisper Quiet: The fan can maintain low RPMs while keeping the ASIC core cool, restoring the silent desktop experience.
- The DigLucky Pricing Promise: Hardware upgrades usually mean price hikes. Not here. Thanks to DigLucky’s robust supply chain and manufacturing scale, we have brought the Bitaxe Gamma 602 to market at the exact same retail price as the older 601. You get superior thermals and higher out-of-the-box hashrate for free.
Phase 3: The 1.7T Breakthrough
Solving the thermal equation with the 602 heatsink was just the prerequisite. Now, we are attacking the final frontier of the BM1370 chip.
If the chip stays cool, the only thing stopping us from reaching higher hashrates is the Power Delivery Network (PDN) and firmware optimization. Pushing past 1.5T requires providing massive, impeccably clean current to the ASIC without voltage droop.
The 2026 Reality: Having pushed the power delivery network (PDN) to its limits, we have standardized the factory-default hashrate of the mass-produced Bitaxe Gamma 602 to a highly stable 1.7 TH/s.
This represents a monumental 50% increase in computational power compared to the original 1.2T baseline, all on a single piece of desktop silicon.
📊 The Bitaxe Evolution Timeline
| Specification | Bitaxe 601 (Standard) | Bitaxe 602 (Current) | Bitaxe 602 (2026 Upgraded) |
|---|---|---|---|
| Heatsink Type | Standard Extruded | High-Density Pin-Fin | High-Density Pin-Fin |
| Factory Hashrate | 1.2 TH/s | 1.5 TH/s | 1.7 TH/s±5% |

| Price Point | Baseline | Same as 601 | Same as 601 |
Breaking the Silicon Limit: Lab Verification at 2.0 TH/s
While our commercial 1.7 TH/s standard is meticulously optimized for 24/7 stability and hardware longevity, our engineering team continues to push the boundaries of the BM1370 silicon.
In a controlled laboratory environment—utilizing enhanced thermal management and precision voltage tuning—we have successfully verified that a single BM1370 chip can sustain a hashrate of 2.0 TH/s.

This successful verification demonstrates a significant power headroom in our hardware design. By standardizing our shipping units at 1.7 TH/s, we ensure that every DigLucky miner operates within a reliable “sweet spot,” providing maximum performance without compromising the lifespan of the ASIC or its components.
Conclusion: Never Settle for Standard
The debate between the Bitaxe 601 vs 602 is officially settled. The 602 is not just a replacement; it is the definitive platform for the BM1370 chip.
By upgrading the thermal architecture without raising the price, DigLucky is ensuring that solo miners have access to the absolute best hardware possible. Now that the 1.7 TH/s version is officially shipping as our new performance standard, the Bitaxe Gamma 602 stands as the definitive high-efficiency solution for modern desktop Bitcoin mining.

Frequently Asked Questions (FAQ)
Q: If the Bitaxe 602 is so much better, why is it the same price as the 601?
A: DigLucky is a source-factory manufacturer, not a dropshipper. By leveraging our massive supply chain network and optimizing our assembly lines, we absorbed the cost of the premium pin-fin heatsink, allowing us to pass the performance upgrade to our users for free.
Q: I have a Bitaxe 601. Can I just flash the AxeOS firmware to reach 1.7T?
A: We do not recommend it. Pushing a standard Bitaxe 601 to 1.7T will likely result in immediate thermal throttling or hardware crashes due to the limitations of the original extruded heatsink. The 1.7T firmware is specifically tuned for the thermal dynamics of the 602.
Q: Is the high-performance 1.7 TH/s version of the Bitaxe Gamma 602 available now?
A: Yes. The 1.7 TH/s optimized units officially entered mass production in April 2026 and are currently in stock at our Shenzhen facility. These factory-assembled units are verified to deliver a stable 1.7 TH/s (upgraded from legacy 1.5T models) and now come standard with an upgraded 40W (5V/8A) power supply to ensure long-term hardware longevity at maximum performance.
