Mining Ethereum (ETH) and Siacoin (SIA) simultaneously using Claymore 9.0 in an ethOS environment offers a powerful way to maximize returns from GPU mining rigs. However, transitioning from default configurations to custom setups—especially when modifying local.conf—can introduce unexpected issues like zero hash rates, system freezes, or boot failures. This guide walks you through diagnosing and resolving common problems while optimizing your dual mining performance.
Understanding the ethOS Configuration System
ethOS is a lightweight Linux-based operating system designed specifically for GPU mining. It uses a hierarchical configuration system where settings are defined in:
remote.conf: Cloud-based configuration (loaded on boot).local.conf: Local overrides that take precedence over remote settings.
When users delete remote.conf and rely solely on local.conf, they gain full control—but also assume full responsibility for correct syntax and logic.

Common Issues After Editing local.conf
The user reports three primary issues after switching to a local-only config:
A. GPUs Show 0 Hash Rate Locally Despite Reporting to Ethermine
Even though the desktop interface shows zero hashrate, Ethermine reports ~13 MH/s. This discrepancy suggests that:
- The miner is running and submitting shares.
- The local monitoring interface (ethOS dashboard) is failing to read GPU stats.
Possible Causes:
- Incorrect or missing miner selection.
- Missing GPU-specific clock settings (
cor,mem) causing instability. - Incomplete flag configuration leading to delayed initialization.
- Driver-level conflict due to improper overclocking.
Recommended Fix:
Ensure globalminer claymore is set. Without this, ethOS may default to ethminer, which doesn't support dual mining.
Update your config with:
globalminer claymoreAlso verify that dual mining is explicitly enabled:
dualminer enabled
dualminer-coin sia
dualminer-pool sia-us-east1.nanopool.org:7777

CPU freezes during editing indicate resource exhaustion or I/O bottlenecks.
Likely Causes:
- Overclocked memory or core clocks destabilizing the system.
- High fan speeds combined with aggressive power tuning reducing PCIe stability.
- USB drive wear or corruption (common with low-quality flash storage).
Best Practices:
- Use
screenortmuxto avoid losing session state. - Edit files remotely via SSH instead of directly on the rig.
- Replace aging USB drives with high-endurance models (e.g., industrial-grade SSDs in USB enclosures).
C. ethOS Fails to Boot After Restart
Reinserting the USB to restore bootability points to filesystem corruption or improper shutdowns.
Prevention Tips:
- Always shut down using
sudo shutdown -h now. - Avoid cutting power abruptly.
- Run
fsckperiodically to check filesystem integrity. - Consider moving to a RAM-based boot mode if supported.

Frequently Asked Questions (FAQ)
Q: Why does Ethermine show hashrate but my rig shows 0?
A: This usually means the miner process is running, but ethOS cannot read GPU metrics—often due to incorrect miner assignment or driver issues. Ensure globalminer claymore is set and restart the rig.
Q: Can I run dual mining without stratumproxy?
A: Yes, but stratumproxy simplifies wallet management across multiple rigs. If disabled, you must define pools directly in Claymore flags.
Q: What does --dual-rate 2 do in Claymore?
A: It reduces SIA mining intensity relative to ETH, lowering GPU load and heat. Use values between 1–3 depending on stability.
Q: How do I check my current worker name?
A: Run hostname in the terminal or view it on your ethOS panel at ethosdistro.com.
Q: Is it safe to overclock all GPUs uniformly?
A: Only if all GPUs are identical and well-cooled. For mixed models, use per-rig (cor, mem) settings to prevent crashes.
Q: Should I keep remote.conf?
A: Yes—unless you need full local control. Keeping remote.conf allows remote updates and easier troubleshooting.

Final Recommendations
Dual mining ETH and SIA using Claymore 9.0 can boost profitability by up to 15–20% compared to single-algo mining—provided the configuration is stable.
Pro Tips:
- Monitor temperatures closely; dual mining increases VRAM usage.
- Test overclocks incrementally.
- Use log analysis (
tail -f /var/log/miner/current) to catch early errors. - Backup working configs before making changes.
For miners scaling beyond one rig, consider centralized config management via remote panels or scripts.
