NerdQX

^{Revision 1.0}

The standard and spearhead of current multi-ASIC home miners based on open hardware.

About

NerdQX is a new development based on NerdQaxe++. NerdQX also has four BM1370 ASIC chips, a different PCB geometry, and significantly improved and simplified safety mechanisms.

The NerdQX was developed as the world's first multi-ASIC home miner for overclocking, which also enables extremely efficient mining. Furthermore, the NerdQX can measure the temperature of all four ASICs separately and directly, in addition to the existing and somewhat less accurate variant.

NerdQX offers full compatibility with the ESP Miner NerdQAxe+ firmware, which has been specially enhanced for the NerdQX. This means you get the benefits of ongoing support and further development on an open source basis.

Many small and large improvements make the NerdQX the new standard for multi-ASIC home miners based on open hardware.

Highlights

Four ASIC BM1370 processors with clock speeds up to 1000 MHz

Unique in open-source home mining worldwide – ready for performance or economy mode.

New PCB design with significantly increased copper and optimized conductor tracks

The entire layout of the NerdQX has been redesigned electrically and thermally. The use of a significantly higher copper ratio in the conductor tracks significantly improves the current carrying capacity of the board – even under permanently high ASIC loads. The wider spacing and targeted routing ensure stable power supply, reduced heat loss, and more even temperature distribution, while at the same time greatly improving efficiency.

Dedicated cooling of the VREGs with custom-made heat sinks

Unlike previous DIY miners, where voltage regulators often remain completely uncooled, NerdQX sets a new standard here: The VREGs have been mechanically offset to enable the best possible airflow and heat dissipation. In combination with a customized, thermally adapted heat sink, the resulting power loss is efficiently dissipated – a concept that has previously only been used in industrial mining rigs. This measure not only extends the service life of the components, but also allows safe overclocking without the risk of thermal instability in the power range for the first time.

NOTE: This heatsink is available from Ix Tech not DigiKey.

XT60 power connector

Industry standard: extremely low contact resistance, high current carrying capacity, and reliable contact - even in mobile or vibration-prone setups.

Mini automotive fuse, set to the NerdQX power rating of 15 amps

Robust, cost-effective, and easy to replace – provides additional protection against short circuits or overcurrent without the need for complicated safety mechanisms, while allowing for simple visual checks of functionality.

4-pin PWM connector for up to three fans or AiO cooling

Modular, efficient, prepared for quiet or aggressive cooling strategies.

Rounded PCB corners for better protection and a high-quality overall impression

A detail that makes safety and manufacturing quality visible.

Proprietary open-source firmware

The NerdQX firmware is based on the established open source NerdQaxe++ firmware, but has been specifically enhanced for the new design and architecture of the NerdQX. These adjustments allow the NerdQX to be precisely controlled in the range from underclocking to high-performance operation without compromising security or transparency.

Significantly improved sensor technology for temperature monitoring of all four ASICs

Precise temperature measurement allows perfect control over thermal development during cooling. In addition to the not entirely accurate temperature measurement of the ASIC, the NerdQX allows direct measurement and output of the current temperature per ASIC processor for the first time.

Collaboration

The NerdQX project was developed by an international team of enthusiasts.

Special thanks go to shufps, who developed the NerdQaxe and the corresponding firmware; without him, much of this would not have been possible. Thanks also go to the many other talented developers who have been involved in the Nerd* projects so far.

Development

The further development of the NerdQX is being actively pursued in order to develop additional ideas and features with the goal of creating the perfect multi-ASIC home miner that sets new standards.
