Claymore 9.0 Dual Mining ETH and SIA: Optimizing Your Mining Setup

Introduction to Dual Mining with Claymore 9.0

Dual mining Ethereum (ETH) and SiaCoin (SIA) using Claymore 9.0 allows miners to maximize hardware utilization by simultaneously mining two cryptocurrencies. This guide covers configuration, troubleshooting, and optimization for Linux/ethOS systems.

Common Issues and Solutions

Problem A: GPUs Display Zero Hashrate Despite Detection

Symptoms:

• GPUs appear in the system but show 0 MH/s locally.
• Pool dashboards (e.g., Ethermine) may display partial hashrates (e.g., 13 MH/s vs. expected 100 MH/s).

Causes:

• Incorrect local.conf flags or overclocking settings.
• Driver conflicts or unstable GPU clocks.

Solutions:

1. Verify Flags: Ensure --cl-global-work 8192 --farm-recheck 200 are correctly set.
2. Reset Overclocks: Temporarily remove core/mem clock adjustments to test stability.
3. Driver Reinstall: Use amd-driver-installer --headless for clean AMDGPU installations.

Problem B: System Freezes During Configuration

Symptoms:

• Sudden CPU freezes when editing files.
• Requires forced reboots.

Solutions:

• Reduce Workload: Lower --cl-global-work to 4096 to decrease GPU load.
• Check Thermal Limits: Ensure maxgputemp 85 isn’t exceeded (use show stats).
• Filesystem Check: Run fsck on the USB drive to repair corruption.

Problem C: Boot Failures After Restart

Solutions:

• Recreate ethOS USB: Use ethos-installer to make a fresh installation.
• Disable BIOS Fast Boot: Ensures proper USB detection.

FAQs

Q1: Can I dual mine ETH and SIA on Nvidia GPUs?

A: Claymore 9.0 primarily supports AMD GPUs. For Nvidia, consider alternatives like T-Rex Miner for ETH and SIA-specific miners.

Q2: Why is my hashrate lower after enabling dual mining?

A: Dual mining splits GPU resources. Adjust --dcri values (e.g., --dcri 30) to balance ETH/SIA workloads.

Q3: How do I monitor GPU temperatures in ethOS?

A: Use show temps or watch sensors for real-time data.
