NerdOctaxe Gamma Complete Setup Guide — 12 TH/s Eight-Chip Solo Mining Beast

What Is the NerdOctaxe Gamma?

The NerdOctaxe Gamma is the most powerful open-source Bitcoin miner ever built for the desktop. Eight BM1370 ASIC chips — the same silicon inside Bitmain’s flagship Antminer S21 Pro — packed onto a single PCB, delivering 9.6–9.8 TH/s at stock settings. That is more hashrate than an entire Antminer S9, the machine that once dominated Bitcoin mining, sitting on your desk and drawing about 200 watts from a 12V power supply. Tuned properly, it pushes past 12 TH/s. This is not a novelty miner. This is a serious piece of hashing hardware.

The NerdOctaxe Gamma runs NerdOS, an ESP-Miner fork purpose-built for multi-chip open-source miners. It connects via WiFi, presents a web dashboard for configuration and monitoring, supports OTA firmware updates, and gives you per-chip control over all eight ASICs. A built-in LILYGO T-Display S3 color LCD shows real-time stats without needing to open a browser. Two physical buttons on the display let you cycle through screens — hashrate, temperature, pool status, individual chip metrics — at a glance.

Every NerdOctaxe Gamma sold by D-Central is hand-assembled in Laval, Quebec by the same team that repairs thousands of Antminers every year. We know BM1370 chips because we work with them daily in industrial machines. We know thermal management because we diagnose and fix cooling failures for a living. We know power delivery because we trace voltage regulator failures on hashboards every week. That expertise is soldered into every NerdOctaxe Gamma we ship.

D-Central Technologies has been a pioneer in the open-source mining ecosystem since its earliest days. We created the original Bitaxe Mesh Stand, developed custom heatsinks for Bitaxe and Bitaxe Hex, and stock every variant of every major open-source miner. The NerdOctaxe Gamma represents the current apex of what open-source mining hardware can do — and we are proud to build it by hand in Canada.

This guide walks you through every step: unboxing, power setup, WiFi configuration, pool selection, frequency tuning across all eight chips, thermal management, ECO mode, and troubleshooting. Whether you are upgrading from a Bitaxe or adding TH-scale hashrate to your solo mining operation, this guide has you covered.

Technical Specifications

Before you begin, here is what you are working with. The NerdOctaxe Gamma is a fundamentally different class of open-source miner — 200 watts of hashing power on a single board.

Performance Modes at a Glance

The NerdOctaxe Gamma supports three distinct operating profiles. Choose based on your priorities — raw hashrate, efficiency, or balanced daily driving.

NerdOctaxe Gamma vs. Antminer S9

For context, here is how the NerdOctaxe Gamma compares to the Antminer S9 — the most iconic Bitcoin miner ever produced:

The NerdOctaxe Gamma delivers S9-class hashrate at one-sixth the power consumption, in a form factor that sits on your desk instead of screaming in a server room. Three generations of ASIC chip evolution — from BM1387 to BM1370 — condensed into an open-source package you control completely.

What’s in the Box

Your NerdOctaxe Gamma from D-Central arrives hand-assembled and tested. Here is what you should find:

• NerdOctaxe Gamma PCB — The main board with 8x BM1370 ASIC chips, ESP32-S3 controller, and LILYGO T-Display S3 color LCD
• 2x Thermalright AXP90-X53 coolers — Pre-mounted aluminum heatsinks with fans, covering all 8 chips
• XT60 power connector — Soldered to the board (the power input — NOT a USB-C device)

If anything is missing or shows signs of shipping damage, contact D-Central support immediately. Every NerdOctaxe Gamma is tested before it leaves our Laval workshop.

What You’ll Need

Safety Warnings

The NerdOctaxe Gamma is a 200-watt device. This puts it in a fundamentally different safety category than a 15-watt Bitaxe. Read this section completely before powering on.

• Power circuit: 208W wall draw on a 120V circuit is about 1.7 amps — well within a standard 15A circuit’s capacity, but do not daisy-chain multiple power strips or share the circuit with other high-draw appliances (space heaters, air conditioners, microwaves). A dedicated circuit or at minimum a circuit with headroom is recommended.
• XT60 connector: The XT60 carries 15–20 amps at 12V. Always ensure the XT60 connection is fully seated — a loose connection under high current generates heat at the contact point and can melt the connector. Push the XT60 in firmly until it clicks.
• PSU quality: Use a reputable 12V power supply rated for at least 240W. No-name PSUs with inflated wattage ratings may deliver dirty power (voltage ripple) that damages ASIC chips or causes instability. Server PSUs (HP, Dell) with XT60 breakout boards are popular and reliable options.
• Surface: Place the NerdOctaxe Gamma on a non-flammable, heat-resistant surface. Do not place it on carpet, paper, fabric, or near flammable materials. A desk, shelf, or metal surface is ideal.
• Do not block the cooler fans: The dual Thermalright AXP90-X53 coolers must have unobstructed airflow. Both intake and exhaust must be clear. Blocking airflow will cause rapid thermal shutdown.
• Do not touch the heatsinks during operation: The heatsinks can reach 55+ degrees Celsius. Not dangerous to a brief touch, but hot enough to cause discomfort. Allow the device to cool for several minutes after shutdown before handling.
• Do not operate unattended for the first 24 hours: During initial setup and burn-in, monitor the device closely. Check temperatures periodically. Once you have confirmed stable operation for 24 hours, the NerdOctaxe can run continuously with periodic remote monitoring.

Step 1: Unbox and Inspect

Before connecting power, take a few minutes to inspect your NerdOctaxe Gamma. Every unit is hand-assembled and tested at our Laval workshop, but shipping can shift components.

1. Visual inspection of the PCB: Look for any obvious shipping damage — cracked PCB, loose components, disconnected wires. The board should look clean and intentional.
2. Verify both Thermalright coolers are seated: The NerdOctaxe Gamma uses two Thermalright AXP90-X53 aluminum coolers to cover all 8 BM1370 chips. Each cooler should sit flat and firm against the PCB with no wobble. Gently try to rock each cooler side to side — if either moves, the mounting may have loosened in shipping. Do not power on until both coolers are firmly secured.
3. Check cooler fan connections: Each Thermalright cooler has a fan. Verify both fan cables are connected to their headers on the PCB. A disconnected fan means 4 chips will run without active cooling — they will overheat within minutes.
4. Inspect the XT60 connector: The XT60 power connector should be firmly soldered to the board. Check for any cracks or loose solder joints at the base of the connector.
5. Check the LILYGO display: The T-Display S3 should be mounted securely. The 1.9-inch color LCD should be free of cracks. The two buttons on the display should click cleanly when pressed.
6. Inspect the USB-C port: The USB-C port is used for serial connection and firmware flashing (not power). Make sure it is intact.

Step 2: Connect the Power Supply

The NerdOctaxe Gamma is powered via a 12V DC XT60 connector. This is a high-current connector common in the RC hobby, drone, and power supply world.

Power Supply Requirements

Recommended PSU options:

• Server PSU with XT60 breakout board — HP DPS-1200FB or Dell 1100W server PSUs are excellent, inexpensive options. Pair with a 12V XT60 breakout board (widely available). These deliver rock-solid 12V at high current with excellent voltage regulation.
• RC/drone 12V power supply — Purpose-built 12V supplies with XT60 output designed for high-current applications. Look for at least 20A / 240W rating from a reputable brand.
• Mean Well LRS-350-12 — Industrial-grade 12V / 29A (350W) supply. Requires wiring an XT60 connector but delivers exceptionally clean power.

Connecting the XT60

1. Ensure the PSU is unplugged from the wall outlet.
2. Connect the XT60 — The XT60 connector is keyed (it only fits one way). Align the connector and push firmly until it seats with a click. Do not force it at an angle.
3. Verify the connection — Give the XT60 a gentle tug to confirm it is fully engaged. A half-seated XT60 under 20A load will overheat.
4. Plug the PSU into the wall outlet.

The NerdOctaxe Gamma will power on immediately. There is no power switch.

Step 3: First Boot

When power is applied, the NerdOctaxe Gamma goes through its boot sequence:

1. Both cooler fans spin up — You should hear both Thermalright fans engage. This confirms power is reaching the board and fan headers.
2. The LILYGO display activates — The 1.9-inch color LCD lights up and shows the NerdOS boot screen, followed by status information (firmware version, WiFi status, hashrate placeholder).
3. NerdOS initializes all 8 BM1370 chips — The firmware runs its initialization sequence, powering up and testing each ASIC chip in order.
4. WiFi access point broadcasts — If no WiFi network is saved (first boot), NerdOS creates a WiFi hotspot for configuration.

If the fans do not spin or the display does not activate, disconnect power immediately. Check the XT60 connection, verify your PSU is outputting 12V, and inspect the board for any visible issues. Contact D-Central support if the device does not boot.

Step 4: WiFi Configuration

On first boot, NerdOS broadcasts a WiFi access point for initial configuration.

Connect to the NerdOS Hotspot

1. On your phone, laptop, or tablet, open WiFi settings.
2. Look for a network named “NerdOctaxe”, “NerdOS_XXXX”, or similar (where XXXX is a unique identifier).
3. Connect to this network. No password is required on initial setup.
4. Your device may show a “no internet” warning — this is normal. You are connected directly to the NerdOctaxe, not to the internet.

Access the NerdOS Web Portal

After connecting to the NerdOctaxe’s WiFi hotspot, open your browser and navigate to:

http://192.168.4.1

The NerdOS dashboard will load, showing the main configuration interface.

Configure Your Home WiFi

1. In the NerdOS dashboard, navigate to the WiFi / Network settings section.
2. Enter your WiFi SSID (network name) — case-sensitive, exactly as it appears in your router.
3. Enter your WiFi password.
4. Click Save. The NerdOctaxe will reboot and attempt to connect to your home network.

Find Your NerdOctaxe’s IP Address

After the NerdOctaxe connects to your home WiFi, you need its new IP address:

• Check the LILYGO display — NerdOS displays the device’s IP address on one of the LCD screens. Press the buttons to cycle through views until you see the network information screen.
• Check your router’s admin page — Look in the connected devices list for “NerdOctaxe,” “NerdOS,” or “ESP32.”
• Use a network scanner — Fing (iOS/Android) or Advanced IP Scanner (Windows) will find all devices on your network.
• Try mDNS — Navigate to http://nerdoctaxe.local or http://nerdos.local in your browser.

Once you have the IP address, bookmark it. You will use it frequently.

Step 5: Configure Mining Pool

With the NerdOctaxe Gamma on your network, it is time to point it at a mining pool. At 9.6+ TH/s, this device is a serious solo mining contender.

Solo Mining with Public Pool (Recommended)

Public Pool is the community-standard solo mining pool for open-source miners. Zero fees, open-source, and built for exactly this use case.

In the NerdOS dashboard, navigate to Mining / Stratum settings and enter:

Alternative Solo Pools

Set Your Bitcoin Address

Your Worker Name is your Bitcoin wallet address. On solo pools, this is where the full block reward (3.125 BTC) gets sent if your NerdOctaxe finds a block.

1. Open your self-custody Bitcoin wallet (Coldcard, Trezor, Sparrow, Electrum, BlueWallet, etc.).
2. Copy a receive address — use a bc1q (native SegWit) address for the lowest fees.
3. Paste it into the Worker Name or Username field in NerdOS.
4. Optionally append a device identifier: bc1q…address.nerdoctaxe1

Double-check the address character by character. Click Save. The NerdOctaxe will reboot and begin mining.

Step 6: Frequency Selection and Fan Curve

After the NerdOctaxe reboots and connects to your pool, it will start hashing at whatever frequency NerdOS defaults to. Now you choose your operating mode.

Setting Stock Frequency (600 MHz)

For initial setup, we recommend running at stock 600 MHz to verify everything is stable:

1. In the NerdOS dashboard, navigate to Tuning or ASIC Settings.
2. Set the Core Frequency to 600 MHz.
3. Set the Core Voltage to the recommended stock value (displayed in NerdOS, typically around 1150–1200 mV).
4. Click Save and allow the NerdOctaxe to restart mining.
5. Monitor for 30 minutes minimum — verify all 8 chips are hashing, temperatures are in the 52–55 degree Celsius range, and shares are being accepted.

Fan Curve Configuration

NerdOS lets you configure the fan curve — how aggressively the dual Thermalright fans respond to temperature changes.

• Default fan curve: NerdOS ships with a reasonable default that ramps fan speed as temperature increases. For stock 600 MHz operation, the default is usually fine.
• Aggressive fan curve: If you plan to tune above 600 MHz, set a more aggressive fan curve that starts ramping earlier (e.g., 40% at 45 degrees, 70% at 50 degrees, 100% at 55 degrees). More airflow at lower temperatures gives you more overclocking headroom.
• Quiet fan curve: If noise is a concern in ECO mode, you can set a gentler curve since ECO’s lower power output generates less heat.

ECO Mode Setup

ECO mode reduces frequency to 495 MHz, dropping power from ~208W to ~153W while maintaining ~8.1 TH/s of hashrate. This is the most efficient operating point — roughly 14 J/TH.

When to Use ECO Mode

• High electricity costs: ECO mode saves ~55W (about 1.3 kWh/day, or $4–6/month at typical North American rates)
• Warm climates or summer: Less power means less heat output and lower chip temperatures
• Noise sensitivity: Lower thermal load means the fans run slower and quieter
• PSU headroom: If your PSU is rated at the minimum 216W, ECO mode gives you comfortable margin
• Running multiple units: ECO mode on several NerdOctaxe units can keep total circuit load manageable

Enabling ECO Mode

1. In the NerdOS dashboard, navigate to Tuning or ASIC Settings.
2. Set Core Frequency to 495 MHz.
3. Adjust Core Voltage — ECO mode may allow slightly lower voltage since the chips are running below stock. Reduce in 10 mV increments and test stability. Lower voltage = less heat = more efficiency.
4. Click Save and let the NerdOctaxe restart.
5. Verify hashrate stabilizes around 8.1 TH/s and temperatures drop noticeably.

Tuning for Maximum Hashrate

For miners who want every hash they can extract, the NerdOctaxe Gamma can be pushed beyond 600 MHz toward 12 TH/s. This requires good cooling, a strong PSU, and patience.

Tuning Procedure

1. Confirm stable baseline: Run at stock 600 MHz for 24+ hours. Record per-chip temperatures, total hashrate, and power draw.
2. Increase frequency by 25 MHz: Move from 600 to 625 MHz. Save and restart.
3. Monitor for 30 minutes: Check all 8 chip temperatures. If any individual chip exceeds 65 degrees Celsius, stop and address cooling for that chip.
4. Repeat in 25 MHz steps: 625 → 650 → 675 → 700 MHz. At each step, monitor for 30 minutes minimum.
5. If instability occurs, increase voltage by 10–20 mV: Higher frequency needs more voltage. But more voltage means more heat — watch the thermal feedback loop.
6. Back off one step from the edge: Once you find the frequency where crashes or high rejection rates begin, drop back 25 MHz. This is your 24/7 tuned setting.

Per-Chip Tuning

With 8 individual BM1370 chips, the NerdOctaxe Gamma gives you the ability to monitor and potentially tune each chip independently. This matters because no two silicon chips are identical — even from the same production batch, individual chips have slightly different characteristics.

Why Per-Chip Monitoring Matters

• Silicon lottery: Some chips run cooler and faster than others at the same voltage. One chip might be perfectly stable at 700 MHz while its neighbor needs 675 MHz.
• Thermal positioning: Chips in the center of the PCB tend to run hotter than edge chips because they are surrounded by other heat sources. The dual coolers help, but position-dependent temperature differences are normal.
• Error detection: If one chip consistently shows higher error rates or lower hashrate, it may need lower frequency or higher voltage relative to the others. Per-chip monitoring lets you identify the weak link.

Monitoring Individual Chips

In the NerdOS dashboard, navigate to the ASIC Status or Chip Details section. You should see all 8 chips listed with individual metrics:

• Per-chip temperature: At stock, all 8 chips should be in the 52–55 degree Celsius range. A chip more than 5 degrees hotter than its neighbors indicates a thermal pad issue or airflow obstruction over that chip.
• Per-chip hashrate: Each chip should contribute roughly 1.2 TH/s at stock (9.6 TH/s divided by 8). A chip producing significantly less may be thermal throttling or unstable at the current frequency.
• Per-chip error rate: Check for chips with elevated error rates. A chip producing hardware errors is running beyond its capability at the current frequency/voltage combination.

Thermal Management

Managing heat across 8 ASIC chips drawing 200+ watts is the critical challenge of the NerdOctaxe Gamma. The dual Thermalright AXP90-X53 coolers are excellent, but proper setup and environment matter enormously.

Understanding the Dual Cooler System

The NerdOctaxe Gamma uses two Thermalright AXP90-X53 aluminum coolers, each covering 4 of the 8 BM1370 chips. This design distributes the cooling load and provides independent airflow over each half of the board.

• Each cooler has its own fan: Both fans must be operational. If one fan fails, 4 chips will overheat rapidly while the other 4 remain cool — you will see a dramatic temperature split on the per-chip dashboard.
• Thermal pads underneath: Each cooler makes contact with its 4 chips through thermal pads. Proper thermal pad contact is essential for heat transfer. If temperatures are uneven between chips under the same cooler, the thermal pad may not be making full contact with all chips.
• Orientation matters: Position the NerdOctaxe so both coolers have unobstructed airflow. Avoid placing anything on top of or directly adjacent to the coolers.

Temperature Reference

Ambient Temperature Impact

With 200+ watts of heat output, ambient room temperature has a significant impact on chip temperatures. A rough rule of thumb: every 5 degree Celsius increase in room temperature adds approximately 3–5 degrees to your chip temperatures.

• Winter in Canada (18–20 °C room): Stock settings will keep chips well within optimal range. Tuning headroom is excellent.
• Summer without AC (28–32 °C room): Stock settings may push chips toward the warm range. Consider ECO mode or improved room ventilation.
• If the NerdOctaxe is your only heat source in a small room: It will raise the room temperature by several degrees. The device heats the room, the warmer room heats the device — a feedback loop. Ensure the room has ventilation or airflow to an adjacent space.

Running Multiple NerdOctaxe Units

Running multiple NerdOctaxe Gamma units multiplies your solo mining odds proportionally. Two units at stock give you ~19.6 TH/s — approaching Antminer S19 territory from open-source hardware on your desk.

Multi-Unit Considerations

• Power budget: Each unit draws ~208W at stock (wall). Two units on a single 15A/120V circuit draw ~3.5A — still well within limits. Three units at ~6.2A total is still safe. But factor in everything else on that circuit. A dedicated circuit is ideal for 3+ units.
• Heat output: Two NerdOctaxe Gammas produce ~416W of heat — equivalent to a small space heater. Three produce over 600W. In winter, this is free heating. In summer, you need ventilation or AC.
• WiFi bandwidth: Each unit uses minimal bandwidth (Stratum protocol is lightweight). However, multiple 200W devices create more EMI. Spread units apart if possible, or use a dedicated 2.4 GHz access point near your mining setup.
• Same Bitcoin address: Use the same Bitcoin wallet address across all units. Append different worker names (e.g., .nerdoctaxe1, .nerdoctaxe2) to identify them on the pool dashboard. Combined hashrate appears as one total on Public Pool.
• Individual IP management: Each unit gets its own IP address. Use DHCP reservations and label each unit (a piece of tape with the IP on the case works). NerdOS’s LILYGO display also shows the IP address.

OTA Firmware Updates

NerdOS supports over-the-air (OTA) firmware updates through the web dashboard. Keeping firmware current is important — updates can include per-chip tuning improvements, better thermal management, new display features, and bug fixes.

Update Procedure

1. Check your current version: The NerdOS dashboard shows the firmware version in the System or About section. The LILYGO display may also show it on the info screen.
2. Download the latest firmware: Get the correct .bin file from the NerdOS or ESP-Miner-Nerd GitHub repository. Make sure you download the build specifically for the NerdOctaxe hardware.
3. Record your settings: Write down your frequency, voltage, pool URL, Bitcoin address, fan curve, and WiFi credentials. Some updates reset configuration to defaults.
4. Navigate to OTA Update: In the NerdOS dashboard, go to System → OTA Update.
5. Upload the .bin file: Select the firmware file and click Update. The upload and flash process takes 1–3 minutes.
6. Wait for reboot: The NerdOctaxe will reboot automatically. The LILYGO display will show the boot sequence again.
7. Verify settings: Check that pool configuration, frequency, and fan curve settings survived the update. Reconfigure if needed.

USB-C Recovery (If OTA Fails)

If an OTA update fails and the NerdOctaxe will not boot properly, you can reflash the firmware via the USB-C port using a computer. This requires:

• A USB-C data cable (not a charge-only cable)
• The esptool.py flashing utility or the ESP web flasher
• The correct NerdOS firmware .bin file

This is a recovery procedure only — normal updates should always use the OTA method through the web dashboard.

Troubleshooting

Chip Thermal Imbalance

Symptoms: One or more chips running 8+ degrees hotter than the others. Uneven hashrate across chips.

1. Check which cooler covers the hot chips: If all hot chips are under the same cooler, that cooler’s fan may be failing or the thermal pads under that cooler may not be making proper contact.
2. Verify fan operation: Look at both cooler fans — are both spinning? A stopped fan is immediately obvious by the temperature split.
3. Check thermal pad contact: If the cooler fan is running but chips are still hot, the thermal pads may have shifted. Power off, carefully remove the cooler, inspect the thermal pads, and remount with even pressure.
4. Center chips run warmer: Chips in the center of the PCB are surrounded by other heat-producing chips and naturally run a few degrees warmer. A 3–5 degree difference between center and edge chips is normal. More than that indicates a cooling issue.
5. Ambient airflow direction: Ensure both coolers have equal access to cool ambient air. If one cooler is against a wall and the other faces open air, you will see a temperature differential.

WiFi Connectivity Issues (EMI-Related)

Symptoms: WiFi drops, intermittent disconnections from pool, shares stop being accepted then resume.

1. Move the NerdOctaxe away from the router: 200W of switching power creates significant electromagnetic interference. Place the miner at least 1–2 meters from your WiFi router or access point.
2. Use a dedicated 2.4 GHz SSID: Band steering on combined 2.4/5 GHz networks can cause the ESP32-S3 to lose connection when the router tries to push it to 5 GHz (which it does not support).
3. Try a different WiFi channel: If other 2.4 GHz devices (microwave, baby monitors, other miners) are nearby, channel congestion can cause drops. Change your router’s 2.4 GHz channel to 1, 6, or 11 (the non-overlapping channels).
4. Add a WiFi access point: If your miner must be far from the main router, place a dedicated WiFi access point near the mining setup. This gives the ESP32-S3 a strong, clean signal.
5. Check the LILYGO display: The display shows WiFi signal strength and connection status. Use this to verify the connection is stable without needing to open a browser.

Power Supply Issues

Symptoms: Random reboots, hashrate drops, one or more chips failing to initialize, NerdOctaxe not powering on.

1. Verify 12V output: Use a multimeter to check your PSU’s output voltage at the XT60 connector under load. It should read 11.8–12.2V. Below 11.5V under load indicates a weak or failing PSU.
2. Check wattage rating: At stock, the NerdOctaxe draws ~208W from the wall. Your PSU must handle this sustained load. A PSU rated for 200W is too close to the edge — 240W minimum, 300W recommended.
3. Check the XT60 connection: A loose or partially-seated XT60 connector under 20A load will generate heat and cause intermittent contact. Disconnect, inspect both connectors for blackening or melting (signs of poor contact), and reconnect firmly.
4. Server PSU fan noise: If using a server PSU (HP, Dell), note that these PSUs have their own high-speed fans that can be noisy. This is normal server PSU behavior. Fan speed adapters are available if the noise is excessive.
5. Multiple units on one PSU: If your PSU has enough wattage, you can technically power multiple NerdOctaxe units from a single PSU using XT60 splitters. However, ensure the total current draw does not exceed the PSU’s rating, and use quality splitter cables rated for the combined current.

LILYGO Display Issues

Symptoms: Display shows incorrect data, display is dark, buttons do not respond.

1. Display is dark but mining works: The LILYGO display is driven by the same ESP32-S3 that controls mining. If mining is working (verify via web dashboard) but the display is dark, try pressing both buttons simultaneously — some NerdOS versions use this as a display wake/sleep toggle.
2. Display shows stale data: If the display appears frozen but the web dashboard shows live data, the display refresh may have crashed. A power cycle will resolve this.
3. Button navigation: The two buttons cycle through display screens. If pressing a button does nothing, try the other button — the button functions may differ by firmware version.

No Hashrate or Very Low Hashrate

Symptoms: Dashboard shows 0 TH/s or significantly below 8 TH/s at stock.

1. Check per-chip status: In NerdOS, look at individual chip status. If some chips show 0 hashrate, they may have failed to initialize. A reboot often resolves initialization failures.
2. Verify PSU is adequate: If the PSU cannot sustain the full load, the voltage sags and chips drop offline. This is the most common cause of partial hashrate.
3. Check pool settings: Incorrect pool URL, port, or Bitcoin address prevents share submission. Shares are still computed locally but not accepted by the pool.
4. Update firmware: Older NerdOS versions may not initialize all 8 chips correctly. Update to the latest firmware.
5. Temperature check: If chips are above 68 degrees, thermal throttling reduces hashrate. Fix the cooling issue first.
