The Modern Minibit Gamma

Description

Why the Modern Minibit Gamma — The Overclocked Bitaxe That Hits Nearly 2 TH/s

The Modern Minibit Gamma is what happens when Bitcoin mining engineers get their hands on the Bitaxe Gamma platform and refuse to leave performance on the table. D-Central’s ASIC repair technicians — the same team that services thousands of mining machines every year — designed a proprietary thermal management system that unlocks the BM1370 chip’s full potential. The result: nearly 2 TH/s from a single 3nm chip, in a case that fits on your desk.

• Nearly 2x the hashrate of a stock Bitaxe Gamma — sustained 1.8+ TH/s, with peaks above 2 TH/s, versus the stock 1.0–1.2 TH/s. Same chip, engineered differently.
• Proprietary thermal management built for overclocking — the Modern Bitaxe Heatsink (40x40x40mm aluminum) paired with a 60mm fan replaces the stock 40mm fan. Larger fan means lower RPM, better airflow, and less noise at higher performance.
• Dual heatsink design — a dedicated voltage regulator heatsink with active cooling keeps the VR under 60°C even at 1000 MHz. Stock Bitaxe units have no VR cooling — this is where overclocks typically fail.
• Assembled and tested in Canada — every unit is overclocked, stress-tested, and validated by D-Central’s team in Laval, Quebec. Not a kit. Not a gamble. A tuned machine.
• $5 from every sale supports OSMU — Open Source Miners United, the community behind Bitaxe, NerdAxe, and the entire open-source mining movement.

Engineered for Overclocking

Overclocking a Bitaxe Gamma is straightforward in software — AxeOS lets you crank the frequency with a slider. The hard part is keeping everything cool and stable when you do. That is the problem D-Central solved with the Modern Minibit Gamma.

The Thermal Problem

The BM1370 ASIC chip generates significantly more heat at 900–1000 MHz than at its stock 525 MHz. But the chip itself is only half the story. The voltage regulator (VR) — the component that feeds power to the ASIC — also heats up dramatically under overclocked loads. On a stock Bitaxe Gamma, the VR has no dedicated cooling. Push the frequency too high and the VR overheats first, causing instability, throttling, or shutdown.

D-Central’s Solution

• Modern Bitaxe Heatsink (40x40x40mm aluminum) — a purpose-built heatsink that sits directly on the BM1370 chip, providing significantly more thermal mass than stock cooling.
• 60mm fan (4000 RPM) — replaces the stock 40mm fan. A larger fan moves more air at lower speed, which means better cooling with less noise. The 60mm fan at 4000 RPM outperforms a 40mm fan at 6000 RPM in both airflow and acoustics.
• Dedicated VR heatsink (3mm base, 6x9x12mm fins) — a separate heatsink mounted directly on the voltage regulator with active airflow from the same 60mm fan. This is the key innovation: the enclosure channels airflow across both the ASIC heatsink and the VR heatsink in a single pass.
• Enclosure-directed airflow — the custom case is not just cosmetic. It functions as an air duct, directing the fan’s output across both thermal zones in sequence. One fan, two heatsinks, one engineered airflow path.

Thermal Performance

At the maximum tested frequency of 1000 MHz:

• ASIC temperature: under 65°C
• Voltage regulator temperature: under 60°C
• Both well within safe operating margins for 24/7 sustained operation

Performance Benchmarks

Every Modern Minibit Gamma is validated against these benchmarks before shipping. All figures measured at stable operating temperature after thermal equilibrium.

Frequency	Hashrate	Notes
525 MHz	1.07–1.08 TH/s	Conservative setting. Low heat, maximum efficiency. Stock Bitaxe Gamma territory.
700 MHz	~1.4 TH/s	Recommended max with a standard 5V/6A power supply. Great balance of performance and longevity.
900 MHz	1.81 TH/s	High performance. Requires 5V/8A PSU recommended. ASIC and VR temps well within safe range.
1000 MHz	~2.0 TH/s	Peak performance. Requires a high-quality 5V/8A+ PSU. Monitor temps via AxeOS dashboard.

For overclocking, increase frequency in 25 MHz steps through the AxeOS web interface. Let each step stabilize for 15–20 minutes before increasing further. The Modern Minibit Gamma’s thermal headroom gives you room to find your ideal balance between hashrate and efficiency.

Enclosure Colors and Customization

The Modern Minibit Gamma ships in D-Central’s custom standing enclosure — designed to direct airflow, not just look good on a shelf. Choose your combination:

Enclosure Finishes

• Silver — clean, industrial. Pairs with Black & Silver grille.
• Bronze — warm metallic. Pairs with Black & Bronze grille.
• Black — stealth mode. Pairs with Red, Blue, Green, Orange, Purple, or Black grille.

Special Edition

Frequently Asked Questions

What makes the Modern Minibit Gamma different from a regular Bitaxe Gamma?

Three things: thermal engineering, overclocking validation, and Canadian assembly. The Modern Minibit Gamma uses D-Central’s proprietary Modern Bitaxe Heatsink with a larger 60mm fan and a dedicated voltage regulator heatsink — components the stock Bitaxe Gamma does not have. Every unit is overclocked to 1000 MHz, validated stable, and stress-tested before shipping. The result is 1.8–2+ TH/s sustained versus the stock Gamma’s 1.0–1.2 TH/s.

What power supply do I need?

The Modern Minibit Gamma uses a standard 5V barrel connector power supply. A 5V/6A (30W) PSU will run the unit at frequencies up to ~700 MHz. For full overclocking potential above 700 MHz, use a 5V/8A (40W+) PSU. Power supplies are available in our shop. Never use a 12V power supply — it will permanently damage the hardware.

How loud is the Modern Minibit Gamma?

Designed for 24/7 desktop operation. The 60mm fan at 4000 RPM is quieter than the stock Bitaxe’s 40mm fan at 6000 RPM — a larger fan moves the same (or more) air at lower speed, producing less noise. Most users describe it as comparable to a quiet desktop PC. You can comfortably run it in a home office or living room.

What are the chances of finding a Bitcoin block?

At ~2 TH/s, you have roughly a 1-in-1.75-million chance per day of finding a full block. Over a year, that is approximately 0.02% cumulative probability. These are long odds — but the ticket costs only $3–5/month in electricity, and the prize is the full 3.125 BTC block reward (currently over $300,000 CAD). Bitaxe-class devices have confirmed multiple solo block finds. Every hash has an independent chance. Every hash counts.

Can I adjust the overclock settings myself?

Yes. The Modern Minibit Gamma ships pre-configured, but AxeOS gives you full control. Through the web dashboard (accessible from any browser on your network), you can adjust the ASIC frequency, core voltage, fan speed target, and temperature limits. Want to run at a conservative 525 MHz for maximum efficiency? You can. Want to push toward 1000 MHz for maximum hashrate? The thermal system was built for it.

Which mining pool should I use?

For solo mining (the primary use case), the two main options are Solo CKPool (solo.ckpool.org) — established, 2% fee, excellent infrastructure — and Public Pool (web.public-pool.io) — self-hostable, fee-free. For pool mining with predictable small payouts, Ocean and Braiins are solid choices. Solo mining is recommended for open-source miners: you’re rolling the dice for a full block reward while directly supporting Bitcoin decentralization.

Does the Modern Minibit Gamma only work on 2.4 GHz WiFi?

Yes. Like all Bitaxe-based devices, it connects via 2.4 GHz WiFi only. Most routers broadcast both 2.4 GHz and 5 GHz bands — make sure you connect the Minibit to the 2.4 GHz network. If your router uses a combined SSID for both bands, check your router settings to ensure 2.4 GHz is enabled. 5 GHz and WiFi 6E (6 GHz) are not supported.

How much electricity does it cost to run per month?

At stock settings (~21W), roughly $2 CAD/month at typical Canadian electricity rates ($0.10/kWh). When overclocked, power draw increases — budget approximately $3–5 CAD/month depending on your frequency setting and local rates. That is the ongoing cost of your solo mining lottery ticket.

Does D-Central offer warranty and support?

Yes. Every Modern Minibit Gamma is assembled and tested by D-Central’s ASIC repair team in Laval, Quebec. If anything goes wrong, you are dealing directly with the Canadian company that built it — and the same team that repairs Antminers, Whatsminers, and Avalons professionally. D-Central offers bilingual support in English and French.

Is the Modern Minibit Gamma open source?

The underlying Bitaxe Gamma platform is 100% open source under the MIT License — hardware schematics, firmware, everything. D-Central’s additions (the heatsink design, enclosure, and overclocking profile) are proprietary engineering on top of that open-source foundation. You get full transparency on the mining hardware and firmware, with D-Central’s thermal expertise layered on top.

Modern Minibit Gamma vs Bitaxe GT — which should I buy?

Both deliver approximately 2 TH/s. The Modern Minibit Gamma uses a single overclocked BM1370 chip on a 5V barrel connector — simpler power setup using the same PSU as standard Bitaxe models. The Bitaxe GT uses two BM1370 chips at stock frequencies on a 12V XT30 connector — better efficiency (~18 J/TH) but requires a different power supply. The Minibit is the better choice if you already own Bitaxe power supplies and accessories. The GT is the better choice for maximum efficiency. D-Central carries both.

What if my Modern Minibit Gamma needs repair?

D-Central operates one of North America’s leading ASIC repair facilities in Laval, Quebec. The same technicians who built and overclocked your Minibit are the ones who can diagnose and fix it. We have serviced 2,500+ mining machines since 2016. No other Bitaxe retailer offers this kind of lifecycle support.

Supporting Open-Source Mining

The Modern Minibit Gamma is built on the Bitaxe platform — one of the most important open-source hardware projects in Bitcoin. The Bitaxe and the broader OSMU (Open Source Miners United) ecosystem exist because a global community of engineers, developers, and Bitcoin believers decided that mining hardware should be transparent, auditable, and accessible to everyone.

$5 from every Modern Minibit Gamma sale goes directly to OSMU to fund continued development of open-source mining hardware and firmware.

The Bitaxe Gamma board is released under the MIT License. The AxeOS firmware is open source. The hardware schematics are publicly available. You own the hardware. You control the software. No telemetry. No vendor lock-in. No permission required.

Every hash you produce with this machine is a vote for decentralized mining. The Bitcoin network is more secure, more censorship-resistant, and more distributed when hash power is spread across thousands of individual miners instead of concentrated in a handful of industrial facilities. That is the mission. Every hash counts.
