How to Set Up and Start Mining with the BTC-T37 Mining Motherboard

Why BTC-T37? Lower Consumption, Higher Profits

Purpose-built for mining, the BTC-T37 is compact, efficient, and simple to scale. It supports up to eight GPUs, has onboard CPU and networking, and offers multiple storage options. Fewer add-ons = lower idle draw and a cleaner build.

BTC-T37 Specifications (as supplied)

  • Processor: Onboard Intel® Celeron® CPU

  • Chipset: Intel® HM77

  • GPU Interface: 8 × PCIe x16 (physical) at PCIe x1 Gen2 speed

  • Memory: 1 × DDR3 SODIMM (1066/1333/1600 MHz)

  • Audio: None

  • Network: Realtek RTL8111F Gigabit LAN (supports PXE/network boot)

  • Storage: 1 × SATA 3.0, 1 × SATA 2.0, 1 × mSATA 2.0

  • USB: 4 × USB 2.0 (rear) + 2 × front-panel USB 2.0 header

  • Super I/O: ITE IT8772E

  • Headers/Extensions: 1 × COM, 1 × PS/2, 1 × chassis fan

  • PSU: 24-pin ATX main power

  • Form Factor: 470 mm × 195 mm

Practical notes: DDR3 SODIMM (laptop-style) RAM, onboard CPU means no separate processor purchase, and mSATA lets you keep wiring tight on open-air frames.

What You’ll Need

  • BTC-T37 motherboard (above) + DDR3 SODIMM (4–8 GB recommended)

  • Storage: mSATA SSD (recommended) or 2.5" SATA SSD (≥120 GB)

  • GPUs: Up to 8, with quality risers (6-pin/PCIe powered)

  • PSU(s): Size for total wattage + 20–30% headroom (e.g., 2000 W for 8 mid/high-end GPUs)

  • Open-air frame, fans, and cable ties for airflow and safety

  • OS: Windows 10/11, HiveOS, or RaveOS (HiveOS is popular for remote control)

  • Wallet address for your chosen coin and a mining pool account (if required)

Step 1 — Assemble the Rig

  1. Mount the board on the frame (standoffs to avoid shorts).

  2. Install RAM (DDR3 SODIMM) and mSATA/SATA SSD.

  3. Power: Connect the 24-pin ATX to the board.

  4. GPUs: Seat risers in the eight PCIe slots; power risers and GPUs with dedicated PCIe cables (avoid splitters where possible).

  5. Cooling: Connect the chassis fan header and arrange airflow across GPUs and the board.

  6. Display/Access: Plug in keyboard, HDMI (via a GPU), and Ethernet to the RTL8111F port.

PSU tips:

  • Prefer a single high-capacity PSU. If using two, use a dual-PSU sync adapter so both turn on/off together.

  • Don’t mix rails on a single device (e.g., don’t power one riser from PSU A and the same GPU from PSU B).

Step 2 — BIOS/UEFI Quick Setup

On first boot (DEL/F2), set:

  • Init Display: PCIe/GPU

  • Above 4G Decoding: Enabled (for 6–8 GPUs)

  • PCIe Speed: Gen2 or Auto (stable with risers)

  • CSM/Legacy: As required by your OS

  • PXE Boot: Optional (handy for network images with the RTL8111F NIC)

  • Fan Control: Full/Performance if temps are high

Save & exit.

Step 3 — Install the OS

HiveOS/RaveOS (recommended for farms):

  • Flash the image to USB/SSD, set worker credentials, boot, and it will auto-enrol to your dashboard.

Windows 10/11 (simple for single rigs):

  • Install to mSATA/SATA SSD.

  • Install GPU drivers (NVIDIA/AMD) and set Power Plan: High Performance.

  • Disable sleep/hibernation/screensaver.

Step 4 — Mining Software (Choose by Algorithm/Coin)

  • SHA-256 (BTC via marketplace/NH): CGMiner, BFGMiner, NiceHash Miner

  • Etchash (ETC): lolMiner, PhoenixMiner

  • KawPow (RVN): T-Rex, TeamRedMiner (AMD)

  • Scrypt (LTC/DOGE): CGMiner (for ASICs), MultiMiner for test labs

  • Multi-algo farms: HiveOS flight sheets, RaveOS templates

Always download miners from the official source. Whitelist in AV if needed.

Step 5 — Connect to Any Mining Pool (Generic)

Every pool gives you a stratum URL, a port, and a wallet (or username) format. Edit your miner settings accordingly.

Generic command-line pattern:


-o stratum+tcp://POOL_URL:PORT -u WALLET_ADDRESS.WorkerName -p x

Windows .bat example (lolMiner for ETC):


lolMiner.exe --algo ETCHASH --pool stratum+tcp://POOL_URL:PORT --user 0xYourWallet.Worker01 --watchdog exit pause

HiveOS flight sheet fields (example):

  • Wallet: 0xYourWallet

  • Coin: ETC (or your target)

  • Pool: “Configure in miner” → stratum+tcp://POOL_URL:PORT

  • Miner: lolMiner (pass --algo ETCHASH in miner extra args)

  • Worker name: Worker01

Step 6 — First Launch & Validation

  1. Start the miner and watch for: GPU detection, hashrate, accepted shares.

  2. In the pool dashboard, confirm the worker appears and shares are submitting.

  3. If hashrate is unstable, test different risers/PCIe slots and check PSU headroom.

Step 7 — Tuning for Efficiency

  • Power Limits & Clocks:

    • NVIDIA: lower power limit first, then adjust core/mem.

    • AMD: set core voltage and memory timing strap as supported.

  • Target temps: 55–70 °C; keep hotspot under vendor limits.

  • Airflow: Front-to-back or bottom-up—avoid recirculation.

  • Cable hygiene: Dedicated PCIe cables per GPU when possible.

Step 8 — Maintenance & Uptime

  • Dust control: Clean filters and fans monthly.

  • Logs: Check rejected share rate (<1–2% ideal).

  • Firmware/Drivers: Update only when stable; test on one rig first.

  • Backups: Export HiveOS worker or keep a Windows image to reflash quickly.

Troubleshooting Cheatsheet

  • No GPU detected: Re-seat riser, try another PCIe slot, swap USB cable, check PSU cable.

  • Rig freezes under load: Increase power limit slightly, reduce memory OC, verify PSU capacity.

  • High rejects: Wrong pool/port, unstable OC, poor network latency—switch to a regional endpoint.

  • Random reboots: Mixed rails on a GPU, bad riser, or undervoltage—standardize cabling and test one card at a time.

Safety & Compliance

  • Use surge protection and proper earthing.

  • Don’t overload circuits; consult a licensed electrician for multi-kilowatt setups.

  • Ensure clear airflow; avoid flammables around the rig.

Wrap-Up

With its onboard Celeron, HM77 chipset, 8× PCIe layout, and PXE-capable Gigabit LAN, the BTC-T37 makes multi-GPU builds clean and efficient. Follow the steps above, point your miner at any pool, and you’ll be hashing—and optimizing—within minutes.
