NerdMiner NerdQaxe++ (4.8TH)

The NerdQaxe++ produces 4.8 TH/s of SHA-256 hashrate at stock 72W power draw (600 MHz clock, 1,150 mV voltage). Rev 6.1 hardware supports overclocking to approximately 6 TH/s at 103W (800 MHz, 1,250 mV). Efficiency runs 14.66 to 15 J/TH stock, 16.5 J/TH overclocked. Built on 4 x BM1370 ASIC chips, the same silicon family powering the industrial Antminer S21 Pro. Real world output typically falls within plus or minus 5 percent of rated hashrate depending on ambient temperature, firmware tuning, and rev revision.

Yes, three confirmed on chain verified block finds with combined rewards exceeding $560,000. Block #944,078 was found on April 7, 2026 by a single NerdQaxe++ unit hashing through the Noderunners solo mining pool at approximately 5 TH/s, earning 3.132 BTC. Block #920,440 was found in January 2025 by a single operator running six NerdQaxe++ units together, earning 3.15 BTC worth approximately $342,000 at the time. A third confirmed block find brings total rewards over the $560,000 mark. These are not marketing claims but documented blockchain events verifiable through any Bitcoin block explorer.

The BM1370 is Bitmain's current generation SHA-256 ASIC chip, the same silicon powering their industrial flagship Antminer S21 Pro at 234 TH/s. The NerdQaxe++ runs 4 x BM1370 chips in parallel on a compact open source board, delivering the industrial class 15 J/TH efficiency that defines current generation Bitcoin mining hardware in a desktop form factor. The "++" designation in the product name specifically indicates the upgrade from BM1368 chips (on the older NerdQaxe+ generation) to the current generation BM1370 silicon.

Igen, teljes mértékben. A projekt teljes hardverrajzokat, PCB tervezési fájlokat (Gerber), firmware forráskódokat (AxeOS az ESP-Minerre alapozva) és alkatrész összesítéseket tesz közzé a GitHubon, engedélyezett szabad szoftver licencek alatt. Bárki, akinek van PCB gyártási hozzáférése, saját NerdQaxe++ hardvereket készíthet. Bárki, akinek szoftveres képességei vannak, módosíthatja vagy auditálhatja a firmware-t. Ez ellentétben áll a zárt kereskedelmi ASIC bányászgépekkel, ahol a hardvertervezések szabadalmaztatottak, és a firmware egy fekete doboz. A közösségi ágvágások és felvételi kérések a GitHubon aktív fejlesztést képviselnek, túllépve azon, amit egyetlen kereskedelmi gyártó nyújthat.

The NerdQaxe++ features an integrated LILYGO T-Display S3, a 1.9 inch color LCD screen with two programmable buttons. The display shows real time hashrate, chip temperature, power draw in watts, efficiency in J/TH, current Bitcoin price, submitted share count, and operational status. This standalone monitoring capability means the device works as a complete functional unit without requiring any network device to see operation. For operators wanting physical presence and visual feedback from their mining hardware in a display or work space, the integrated screen is meaningful. The ESP32-S3 controller drives the display alongside mining operations.

WiFi 2.4GHz through the ESP32-S3 controller. No Ethernet port. Initial setup connects the device to home WiFi through a captive portal interface. Subsequent management happens through the AxeOS web interface accessible from any device on the same network. Pool configuration, hashrate monitoring, firmware updates, and performance tuning all run through the browser interface. ESP32-S3 does not support 5GHz WiFi, so plan 2.4GHz coverage in your deployment location. If your router only broadcasts 5GHz, you will need to enable 2.4GHz or position the device near a 2.4GHz capable access point.

Approximately 1 in 1.45 million daily odds, 1 in 47,900 monthly odds, 1 in 3,950 annual odds of finding a Bitcoin block at current network difficulty. Finding a solo block delivers the full block reward (currently 3.125 BTC plus transaction fees, approximately $300,000+ at April 2026 BTC price). Expected value math: ($300,000 reward × 1/3,950 annual probability) = $76 annual expected value per unit, against approximately $44 annual electricity cost at $0.07 per kWh. Mathematically positive expected value, though with extreme variance. Running multiple units linearly improves odds: 6 units improves annual odds to 1 in 660.

Universal 200 to 240V input, with ships with PSU from MillionMiner. At 72W stock draw, electricity cost runs approximately $44 per year at $0.07 per kWh or $63 per year at $0.10 per kWh residential rates. Overclocked at 103W: approximately $63 per year at $0.07 per kWh. Works on standard European Schuko (230V), UK BS 1363, Middle Eastern 220 to 240V commercial, or North American 240V NEMA 6 outlets without voltage conversion. For running multiple units or overclocked operation, verify your circuit has adequate amperage headroom beyond the device draw.

Yes on Rev 6.1 hardware. Overclock specifications: 800 MHz clock and 1,250 mV voltage produce approximately 6 TH/s at 103W and 16.5 J/TH efficiency. Rev 6.1 specifically addresses overclock reliability through the 15A XT30 power connector, 1 oz copper traces reducing board temperatures by 21.4 percent, and spring mounted heatsink for uniform thermal contact. Some retailers void warranty on overclocked operation, so verify warranty terms with your specific supplier before attempting. AxeOS firmware provides overclock tuning through the web interface without requiring external flashing tools.

Hashrate and architecture class apart. Bitaxe Gamma 601: single BM1370 chip, 1.2 TH/s at 17W. NerdQaxe++: four BM1370 chips, 4.8 TH/s at 72W. The NerdQaxe++ produces 4 times the hashrate at 4.2 times the power, essentially linear scaling. Solo mining odds improve proportionally: 1 in 3,950 annual odds for NerdQaxe++ versus 1 in 15,800 for Gamma 601. Additional differentiators: the NerdQaxe++ includes integrated LCD display (Gamma 601 does not), draws more power requiring dedicated outlets rather than USB-C adapter, costs meaningfully more at acquisition. For serious solo mining commitment, the NerdQaxe++ wins. For minimum entry cost to open source mining, the Gamma 601 wins.

Standard AxeOS setup. Step one: connect included PSU to 200 to 240V outlet. Step two: device boots and broadcasts a WiFi setup network (shows on LCD display). Step three: connect to device WiFi from your phone or computer, open captive portal in browser. Step four: enter your home WiFi credentials, device joins network and reboots. Step five: find device IP (shown on LCD display) or through router DHCP client list. Step six: open AxeOS web interface, configure mining pool URL and Bitcoin wallet address, verify hashrate reaches 4.5+ TH/s within 2 to 3 minutes. For solo mining, configure a solo mining pool like Solo CK Pool or Noderunners (where Block #944,078 was found).

Ideal for home deployment. 40 dB effectively silent operation, smaller than a typical paperback book, draws less power than most household appliances, no special electrical infrastructure required. Deploy on desks, bookshelves, living rooms, bedrooms, home offices, or dedicated mining spaces without noise considerations. The integrated LCD display makes it a functional desk accessory beyond just mining hardware. Bitcoin enthusiasts often deploy multiple units as both functional mining fleet and physical expression of their commitment to the network.

Yes, and the block finds demonstrate why this strategy works. Block #920,440 was found by a single operator running six NerdQaxe++ units (36 TH/s total). At approximately $3 monthly electricity per unit at $0.07 per kWh, six units run for $18 per month for a shot at 3.125 BTC. Six units improves annual solo mining odds to 1 in 660, versus 1 in 3,950 per single unit. AxeOS supports swarm monitoring across multiple units on the same network through unified dashboard. Stack and rack multiple units with individual WiFi connections or single mesh network coverage.

Any Stratum compatible Bitcoin pool through AxeOS configuration. For solo lottery mining (the primary use case): Solo CK Pool, Noderunners solo mining pool (where Block #944,078 was found), Public Pool, and similar solo mining services that split block rewards with contributing shares. For pool mining if desired despite minimal revenue: standard pools like Foundry USA, F2Pool, AntPool, and ViaBTC all work. Most operators configure solo pools specifically to capture full block rewards on the rare occasions they occur.

Significant upgrade. NerdQaxe+ Hyd: 2.5 TH/s with passive cooling, BM1368 chips (older generation silicon). NerdQaxe++: 4.8 TH/s with active fan cooling, BM1370 chips (current generation silicon). The "++" nearly doubles hashrate, upgrades to newer chip silicon, improves efficiency through the BM1370 architecture, and adds active cooling that enables higher sustained clock speeds. Trade off: 40 dB acoustic signature from active fans versus passive silent operation of the Hyd variant. For operators prioritizing solo mining odds, the NerdQaxe++ wins decisively. For operators requiring absolutely zero noise, the Hyd variant remains relevant.

Community manufacturer warranty on the complete device covering manufacturing defects under normal operation. Warranty terms vary by the specific manufacturer producing the NerdQaxe++ batch (open source hardware can be manufactured by multiple parties including Power Mining, Altair Technology, D-Central, Solo Satoshi, and others). Typical warranty period runs 3 to 12 months depending on manufacturer. Warranty exclusions include damage from overclocking (though Rev 6.1 hardware handles overclock reliably), inadequate cooling, operation outside specified environmental ranges, and physical mishandling. MillionMiner routes warranty claims through the appropriate batch manufacturer.

Any SHA-256 proof of work cryptocurrency. Primary target: Bitcoin (BTC) for solo lottery mining. Amazon listings document BTC, BCH, BSV, NMC, XEC, PPC, FB as supported coins through appropriate pools. Most operators configure BTC solo mining specifically for the 3.125 BTC block reward opportunity. Merged mining configurations through supporting pools can add marginal BCH and BSV rewards alongside Bitcoin contribution.

Yes, arguably the best Bitcoin hardware gift available under $1,000. Integrated LCD display showing real time hashrate and Bitcoin price makes it a functional desk accessory beyond just mining hardware. Confirmed block finds provide real upside potential (Block #944,078 on April 7, 2026 earning 3.132 BTC proves it works). Home friendly deployment at 40 dB with universal voltage input means recipients can use it without any special infrastructure. Open source hardware ethos aligns with Bitcoin values. Sub $500 price tier at most retailers. Orange pilling gift potential is substantial.

Minimal. At 72W stock operation, annual electricity cost runs approximately $44 at $0.07 per kWh, $50 at $0.08 per kWh, $63 at $0.10 per kWh residential rates. Less than $5 per month. Maintenance is essentially zero: no moving parts to service beyond the dual ball bearing fans (rated for years of operation), no coolant to replace, no fluid infrastructure. Annual dust cleaning with compressed air is the only recurring maintenance. Firmware updates arrive through AxeOS community development without manufacturer dependency.

Within open source solo mining: the Bitaxe Gamma 601 at 1.2 TH/s represents the single chip entry point, the Bitaxe Touch at 1.6 TH/s adds standalone touchscreen interface, and the Bitaxe Supra Hex 701 at 4.2 TH/s provides alternative quad chip architecture. Scale up path for solo mining enthusiasts: running multiple NerdQaxe++ units improves block odds proportionally (the January 2025 block find used six units). For operators wanting to transition from solo lottery mining to pool mining revenue generation: Antminer S21 XP at 270 TH/s or Whatsminer M70S+ at 244 TH/s provide industrial scale Bitcoin mining. Cross algorithm diversification options include Antminer KS7 for Kaspa, Antminer L11 for Litecoin and Dogecoin, Antminer Z15 for Zcash. MillionMiner's ASIC hosting service primarily serves industrial hardware.
