NMQAxe++ White Bitcoin Miner – 4× BM1370 – 4.8TH/s Default / Up to 5.7TH/s – Touchscreen

The NMQAxe++ ASIC Bitcoin Miner is a powerful four-chip SHA-256 home miner designed for enthusiasts looking for considerably more performance than a traditional single-chip miner while retaining a compact, desktop-friendly design.

Powered by 4 × BM1370 ASIC chips, the NMQAxe++ typically delivers approximately 4.6–4.8 TH/s at its standard/default settings, with performance of up to approximately 5.7 TH/s available through advanced tuning.

Each NMQAxe++ supplied by eHasher also features an additional dedicated VRM cooling fan. This eHasher cooling enhancement provides additional airflow directly across the miner's voltage regulation and power delivery components, helping to control temperatures during continuous operation and advanced tuning.

Designed for both solo mining and pool mining, the NMQAxe++ can be used with Bitcoin (BTC), Bitcoin Cash (BCH), eCash (XEC), DigiByte (DGB) and other compatible SHA-256 cryptocurrencies.

With Wi-Fi connectivity, advanced monitoring and tuning, intelligent electrical protection and an impressive 2.8-inch full-colour touchscreen, the NMQAxe++ provides serious multi-chip mining performance in a compact home-friendly package.

Approx. 4.6–4.8 TH/s Default – Up to Approx. 5.7 TH/s Tuned

At its standard/default operating settings, the NMQAxe++ typically delivers approximately 4.6–4.8 TH/s, providing an excellent balance between hashrate, electrical efficiency, temperature and noise.

For experienced users wanting additional performance, frequency and core voltage settings can be adjusted through the miner's management interface. During eHasher testing, approximately 5.5–5.7 TH/s has proven to be a realistic upper tuning range.

Although higher performance figures may sometimes be possible depending on the individual miner, firmware, cooling and operating environment, eHasher advertises approximately 5.7 TH/s as the maximum tuned performance rather than claiming performance that may activate the miner's protection circuitry or may not be sustainable on every unit.

Increasing frequency and core voltage will increase power consumption and heat output. Advanced tuning should therefore be carried out gradually while carefully monitoring the miner's operating temperatures.

Enhanced eHasher VRM Cooling

The NMQAxe++ uses a substantial main heatsink and active fan cooling system to remove heat from the ASIC chips.

In addition, units supplied by eHasher feature an additional dedicated VRM cooling fan positioned to provide targeted airflow across the voltage regulation and power delivery area of the PCB.

This additional cooling has been fitted by eHasher to improve airflow around these components and assist temperature management during both standard operation and advanced performance tuning.

During eHasher testing, typical VCORE / power-stage temperatures of approximately 72–75°C have been observed at standard settings producing around 4.6–4.8 TH/s.

When tuned towards approximately 5.5–5.7 TH/s, temperatures of approximately 92–105°C may be observed depending on frequency, core voltage, ambient temperature, cooling conditions and individual component characteristics.

Advanced Power-Stage Temperature Monitoring

An important feature of the NMQAxe++ is the way in which its power delivery temperature is monitored.

The miner uses a Texas Instruments CSD95472Q5MC power stage. This component provides a dedicated TAO/FAULT temperature analogue output, which reports a voltage proportional to the internal die temperature.

This is important when interpreting the temperature displayed by the NMQAxe++, because this measurement should not be directly compared with PCB, external VRM or surrounding board temperature measurements used by some other miner designs.

A power-stage temperature approaching or exceeding 100°C may therefore initially appear unusually high when compared with another miner displaying a PCB-level temperature, even though the two readings may represent significantly different measurement points.

According to Texas Instruments, the CSD95472Q5MC has a recommended operating temperature range of -40°C to 125°C, with an absolute maximum operating junction temperature of 150°C.

For customers wanting to examine the component specifications directly, the manufacturer's technical datasheet is available here:

The NMQAxe++ firmware also incorporates temperature monitoring and protection designed to prevent the power circuitry from being operated beyond its intended limits.

Intelligent Current / Overload Protection

The NMQAxe++ incorporates intelligent current and overload protection designed to protect the miner's power delivery circuitry when advanced tuning settings demand excessive current.

If frequency or core voltage settings are pushed beyond the electrical limits of the miner, the protection system can intervene and stop normal mining operation rather than allowing the miner to continue operating under excessive electrical load.

If protection is activated, performance settings should be reduced towards the standard/default configuration before normal operation is resumed.

This is particularly useful when experimenting with advanced tuning because it provides an additional level of protection against excessively aggressive operating settings.

2.8" Full-Colour Touchscreen Display

One of the standout features of the NMQAxe++ is its 2.8-inch full-colour IPS capacitive touchscreen.

Rather than simply displaying a fixed status page, the touchscreen provides access to a variety of display screens showing different mining, system and cryptocurrency information.

Depending on the selected display mode, information can include:

• Current hashrate
• ASIC and system information
• Power and operating statistics
• Temperature information
• Mining statistics
• Network information
• Cryptocurrency market information
• Clock display
• ASIC / hashrate distribution information

The display can be changed directly using the touchscreen interface, allowing you to quickly select the information you want to see without accessing the web management interface.

Custom Photo Screensaver

The NMQAxe++ allows you to upload your own image for use with the screensaver function, adding an extra level of personalisation to the miner.

This is particularly useful for desktop or home display use and allows you to personalise the unit with your own photograph, logo or other compatible image.

Simple Plug & Play Setup

Getting started is straightforward. Simply connect the supplied 12V / 10A power supply, power on the miner and connect it to your Wi-Fi network.

Once connected, the miner's local IP address can be used to access its web-based management interface from another device on the same network.

No specialist mining hardware or networking knowledge is required for standard operation, making the NMQAxe++ suitable for newcomers to multi-chip home mining as well as experienced mining enthusiasts.

Advanced Performance Tuning & Customisation

The NMQAxe++ provides extensive configuration options through its management interface, including:

• ASIC core voltage settings
• Mining frequency and clock speed
• Mining pool configuration
• Screen brightness
• Display orientation and screen rotation
• Screensaver settings
• Custom screensaver image
• Performance monitoring
• Temperature monitoring

This allows experienced users to find their preferred balance between hashrate, power consumption, operating temperature and noise.

Performance & Tuning Information

Approximately 4.6–4.8 TH/s is the expected performance at the standard/default configuration. Performance of up to approximately 5.7 TH/s may be achievable through advanced tuning.

Hashrate naturally fluctuates and individual results can vary depending on operating settings, firmware, ambient temperature, cooling conditions and individual ASIC characteristics.

Increasing mining frequency or core voltage increases power consumption and heat output. Temperatures should therefore be monitored carefully whenever performance settings are changed.

During eHasher testing, VCORE / power-stage readings of approximately 72–75°C at standard settings and approximately 92–105°C when heavily tuned have been observed. These figures are provided as examples of observed operation and are not guaranteed operating temperatures.

The miner's built-in current, overload and thermal protection may intervene if operating settings demand excessive current or temperature limits are approached. If protection activates, tuning settings should be reduced before operation is resumed.

The NMQAxe++ combines four BM1370 ASIC chips, multi-terahash SHA-256 performance, intelligent electrical protection, advanced power-stage temperature monitoring and a highly customisable touchscreen interface in a compact home-friendly package.

With the addition of eHasher's dedicated VRM cooling fan, each unit receives additional targeted cooling to the power delivery area, providing an enhanced cooling configuration for both standard operation and enthusiasts who want to explore advanced tuning.
