Cryptocurrency mining continues to evolve as market dynamics shift and new opportunities emerge. With Bitcoin, Ethereum (ETH), and Zcash (ZEC) experiencing price corrections, many miners are actively seeking alternative coins that offer strong potential and manageable mining difficulty. Enter Ethereum Classic (ETC) — a blockchain with growing momentum, increased exchange listings, and rising value.
This guide walks you through setting up a 6-GPU mining rig using the Biostar TB350-BTC motherboard to mine Ethereum Classic, covering hardware selection, system setup, wallet configuration, and optimization tips. Whether you're expanding your mining portfolio or diving into ETC for the first time, this step-by-step tutorial ensures you’re equipped for success.
Why Mine Ethereum Classic (ETC) in 2025?
Ethereum Classic is more than just a legacy fork of Ethereum — it’s a decentralized, proof-of-work blockchain that has gained renewed interest due to its resilience and growing adoption. Unlike ETH, which transitioned to proof-of-stake, ETC remains fully mineable, making it an ideal target for GPU miners.
Recent developments have boosted ETC’s visibility:
- Listed on major exchanges like Huobi and upcoming support on OKCoin
- Stable network performance with consistent block rewards
- Trading around $130+ per coin, showing strong valuation potential
Most importantly, mining difficulty remains relatively low compared to saturated networks like ETH pre-merge or Ravencoin. This creates a sweet spot for miners looking for profitable alternatives without needing cutting-edge ASICs.

Hardware Setup: Building Your 6-GPU Mining Rig
To efficiently mine ETC, you need a stable and scalable mining rig. The Biostar TB350-BTC motherboard is purpose-built for multi-GPU configurations, supporting up to six graphics cards — perfect for maximizing hash rate while maintaining system stability.
Key Components Overview
- Motherboard: Biostar TB350-BTC
Features six PCIe slots (all extended via riser cables), optimized BIOS settings for mining, and AMD Ryzen CPU compatibility. - Graphics Cards: GTX 1050 Ti (x6)
While not the most powerful GPUs, the GTX 1050 Ti offers excellent power efficiency, drawing only about 75W per card. This makes it ideal for low-power rigs aiming for sustained profitability. - RAM: 8GB DDR4 (e.g., Asgard Ram赤)
Mining doesn’t require large memory capacity. A single 8GB stick is sufficient for running lightweight mining OS environments. - Power Supply Unit (PSU): 600W Modular (e.g., Segotep GP700P)
With six low-power GPUs, a reliable 600W PSU can handle the load. Ensure it has multiple SATA power connectors for powering PCIe risers. - PCIe Riser Cables (x6)
All six GPUs connect via USB-style risers. Use high-quality, shielded cables to avoid signal loss or crashes.
Assembly Tips
- Mount the motherboard securely on a non-conductive surface.
- Install the CPU (even a budget Ryzen 3 or Athlon works).
- Connect all six GPUs using PCIe risers.
- Power each GPU using SATA-to-Power adapters from the PSU.
- Double-check all connections before powering on.
BIOS Configuration: Streamlined Mining Settings
One of the biggest advantages of the Biostar TB350-BTC is its mining-optimized BIOS. Recent firmware updates simplify setup significantly.
How to Update BIOS
Download the latest BIOS file from Biostar’s official support page.
- Model: TB350-BTC(707)
- File: B35BG707.BSS.rar
- Extract and copy to a USB drive formatted as FAT32.
- Boot the system with the USB inserted.
- Press
DELto enter BIOS. - Press
F3→ Confirm → Load Default Values. - Save and reboot.
The updated BIOS automatically configures:
- Multi-GPU support
- Resizable BAR settings
- PCIe lane distribution
- Fan curves and stability parameters
No manual tweaking required — just plug in and start mining.
Software Setup: Installing the Miner and Joining a Pool
Now that your hardware is ready, it’s time to configure the software stack.
Step 1: Choose a Mining OS or Windows Setup
You can run mining on:
- Windows 10/11 (easier for beginners)
- Specialized Linux-based mining OS like HiveOS or SimpleMiner (better performance)
For this guide, we assume Windows installation with proper GPU drivers installed.
Step 2: Download a Mining Client
Use a trusted dual-mining tool like PhoenixMiner or GMiner, which support both ETH and ETC.
Example command line for PhoenixMiner:
miner.exe -pool etc.f2pool.com:1800 -wal YOUR_ETC_WALLET_ADDRESS -pass x -proto 2Ensure your miner is set to target ETC (Ethereum Classic), not ETH.
Step 3: Set Virtual Memory
Windows users must increase virtual memory to prevent crashes during mining:
- Go to System Properties > Advanced > Performance Settings > Advanced > Virtual Memory.
- Set custom size: Initial = 16000 MB, Maximum = 32000 MB.
- Apply and restart.
Creating an ETC Wallet: Secure Your Earnings
Before mining begins, you need a secure wallet to receive payouts.
Option 1: Exchange Wallet
Sign up on platforms like:
- OKX
- Huobi
- Bitrue
Navigate to “Funds” → “Deposit” → Select ETC (Ethereum Classic) → Copy your unique deposit address.
Option 2: Cold Wallet (Recommended)
For better security, use:
- Ledger Nano X (hardware wallet)
- Exodus or Trust Wallet (software wallets)
👉 Secure your mined ETC with industry-leading wallet protection and exchange integration.
Mining Performance & Profitability
After running the 6 x GTX 1050 Ti rig for 16 hours, the total output was approximately 0.2 ETC.
Based on current prices (~$130/ETC), that equals about **$26 in earnings over 16 hours — roughly $39/day** if scaled continuously.
| Metric | Value |
|---|---|
| Total Hashrate | ~120 MH/s |
| Power Consumption | ~450W |
| Daily Earnings | ~0.3 ETC ($39) |
| Monthly Profit (est.) | ~$1,170 |
Note: Actual profits depend on electricity costs, pool fees, and market volatility.
Frequently Asked Questions (FAQ)
Q: Can I use other GPUs besides GTX 1050 Ti?
A: Yes! Higher-end cards like RX 580, RX 6700 XT, or RTX 3060 Ti offer better hashrates but consume more power. Adjust PSU and cooling accordingly.
Q: Is ETC still profitable after the Ethereum merge?
A: Absolutely. With many miners shifting from ETH to ETC post-merge, the network has seen increased hashpower — but demand and price have kept pace, maintaining profitability.
Q: Do I need a separate CPU cooler?
A: While the stock cooler works, adding an aftermarket cooler improves longevity, especially in enclosed mining frames with poor airflow.
Q: How often should I update my miner software?
A: Check monthly for updates. Developers frequently release optimizations and bug fixes that improve stability and efficiency.
Q: What happens if my rig crashes during mining?
A: Most modern miners auto-restart after crashes. Enable “auto-restart on failure” in your batch script or mining OS settings.
Q: Is cloud mining ETC worth it?
A: Generally no. Cloud mining contracts often lack transparency and return less than self-mining with full control over hardware.
Final Thoughts: Is ETC Mining Right for You?
Ethereum Classic stands out as one of the most viable GPU-mineable cryptocurrencies in 2025. Its combination of strong exchange support, growing community, and low entry barrier makes it ideal for both new and experienced miners.
