NerdOctaxe Specs: 9.6 TH/s, 150W, 8x BM1370 Chips

The NerdOctaxe has emerged as a compact powerhouse in the mini Bitcoin mining market. Looking at this unit up close shows its exceptional build quality and smart engineering choices that improve both performance and reliability.

Build Quality and Design Overview

The NerdOctaxe's solid construction becomes apparent right out of the box. Eight high-performance S21 Pro BM1370 ASIC chips sit in a well-laid-out arrangement. These chips match those in larger industrial miners, just packed into a smaller space. A custom 3D-printed stand raises the unit to let air flow better.

The front panel features an OLED display that shows up-to-the-minute mining stats like hashrate, temperatures, and IP address. You can monitor everything without connecting to a computer. The open-source AxeOS software gives users full control of their mining operations. A smart design touch includes a standard 15 amp automotive fuse as a failsafe that's quick to replace if needed.

Cooling System: Dual 120x25mm Fans

Bitcoin miners need excellent cooling, and the NerdOctaxe delivers with its dual low-profile 120x25mm cooling fans. These fans keep air moving steadily across heat-generating parts. My tests showed impressive results - ASIC temperatures stayed around 55°C while VRM temperatures held at 48°C. The room temperature was 73°F at the time.

The unit's heatsinks sit strategically on both ASIC chips and MOSFET sections to improve cooling. This reliable thermal setup helps maintain ideal temperatures during long mining sessions.

Power Supply: 216W with XT30 Connector

A robust 216W power supply comes with the NerdOctaxe, outputting 12V at 18 amps. The unit employs a XT30 connector instead of standard options. This creates an extra-secure connection that won't disconnect by accident during operation. The power brick can heat up substantially during extended use. Many users lay it on its side or add extra cooling to prevent overheating.

Efficiency Rating: 15 J/TH Explained

The NerdOctaxe draws about 178W at the wall while delivering 9.6 TH/s at stock settings. This gives an efficiency rating close to 15 J/TH. This efficiency stands as a good match for industrial-grade miners, especially in a home mining unit.

Overclocking to 1200mV core voltage pushes the hashrate above 10 TH/s, though power use rises to 199W. The slight drop in efficiency still makes this a great choice for home miners who want maximum output without huge power costs.

Setup Process: From Unboxing to Mining in 10 Minutes

The NerdOctaxe mini Bitcoin mining machine setup is simple, even if you're new to cryptocurrency mining. This compact unit takes about 10 minutes to start mining, unlike industrial miners that need complex setups.

Wi-Fi Connection and AxeOS Interface

The NerdOctaxe powers up right after you plug in the power adapter through its specialized XT30 connector. The screen shows the unit's name and a Wi-Fi network ID that looks like "Nerd Ax 702D".

Your smartphone needs to connect to this network first. The web interface opens by itself and shows the open-source AxeOS dashboard. Beginners will appreciate its accessible interface. You can start the setup by tapping "Settings".

This Wi-Fi setup lets you place the NerdOctaxe anywhere near a power outlet without needing an Ethernet cable.

Joining ckpool.org for Solo Bitcoin Mining

The settings require:

1. Your home Wi-Fi details

2. Mining pool settings

I used ckpool.org as my main stratum pool for solo Bitcoin mining and added a backup option. You can also connect it to your Bitcoin node if you have one, like a FutureBit Apollo. The miner starts working once you save these settings and connect to your home network.

The hashrate reaches a stable 9.6-9.8 TH/s at stock settings in about 10-12 minutes - exactly as promised. You can check your worker's hashrate on ckpool.org's dashboard to confirm the connection.

Original Configuration Tips for Beginners

New miners should remember these tips:

• Monitor temperatures: Check ASIC temperatures on the interface (55°C is normal)

• Record your IP address: You'll find it on the OLED screen for remote access

• Power brick placement matters: The adapter heats up during long runs, so raise it or add extra cooling

Performance Testing: Hashrate, Power Draw, and Overclocking

My rigorous testing of the NerdOctaxe mini Bitcoin mining machine reveals why this unit outperforms other compact mining options in the market. Let me share my real-life experience with this device.

Stock Performance: 9.6 TH/s at 178W

The miner showed promising results right from the start. The hashrate climbed to 9.5 TH/s in just 10 minutes and settled between 9.6-9.8 TH/s, which matches the manufacturer's specs perfectly. My watt meter readings showed 178W at the wall - a bit above the claimed 150W but still remarkable for this output. The OLED display tracked the hashrate continuously and showed occasional jumps to 10 TH/s before I even tried overclocking.

Overclocking Results: 10+ TH/s at 199W

The AxeOS interface made it easy to boost performance. I skipped the "Danger Zone" advanced options and just bumped up the core voltage to 1200mV from its default setting while keeping the 600MHz frequency. The NerdOctaxe responded quickly after a reboot. Within 12 minutes, it pushed over 10 TH/s while drawing 199W at the wall. Solo miners will appreciate this trade-off - a modest 12% power increase for 5-8% more hashrate.

Temperature and Noise Levels in Home Use

My testing environment stayed at 73°F, and the dual 120x25mm fans did an excellent job with cooling. The ASIC temperature leveled off at 55°C with VRM temperatures at 48°C - both safely within limits. The power supply runs hot during long mining sessions, so you should raise it or add extra cooling for round-the-clock operation. The low-profile fan design keeps noise at acceptable levels for a home office setup.

Efficiency vs NerdQaxe++ and Hydro Units

The NerdOctaxe packs twice the punch of its siblings - the NerdQaxe++ (4.4 TH/s) and Hydro (5 TH/s) models. My overclocked unit hit 10.6 TH/s on ckpool.org, confirming these numbers. You'll pay about the same as two NerdQaxe++ units ($680), but it takes up similar space and offers better value in hashrate per dollar and space efficiency. The 15 J/TH efficiency rating makes this machine a smart choice for home Bitcoin miners who want balanced performance and power usage.

Use Cases and Real Earnings After 30 Days

I've been running the NerdOctaxe non-stop for a month, and now I can share real earnings data that shows what home miners should expect. This 8x BM1370 chip powerhouse proves its worth beyond the impressive specs.

Solo Mining Bitcoin: What to Expect

My experience solo mining Bitcoin with the NerdOctaxe through ckpool.org showed reliable performance. The unit delivered a steady 10.6 TH/s hashrate at the time it was overclocked. Mining Bitcoin solo is basically a lottery ticket - a miner this size might need years to find a block with current network difficulty. Many enthusiasts still enjoy this aspect because they might get lucky.

Mining BCH and DGB with NerdOctaxe

The sort of thing I love about this mini mining machine is its performance with Bitcoin Cash and DigiByte. These SHA-256 algorithm cryptocurrencies give smaller miners more frequent rewards. My tests involved switching between these alternatives, which turned out to be more profitable than direct BTC mining for home users. The open-source AxeOS software lets you switch between coins easily.

30-Day Earnings Breakdown and ROI Estimate

The earnings changed with market conditions during my 30-day test:

• Daily average: $0.65-0.80 (depending on coin mined)

• Monthly total: Approximately $22-24

• Electricity cost (@$0.12/kWh): $13-15 monthly

The unit costs $680, so you'll need about 30-36 months to break even at current rates. This machine makes more sense for people looking to hedge against future price increases rather than quick profits.
