Dual Mining ETH and SIA with Claymore 9.0 on ethOS

Written by

Dual mining Ethereum (ETH) and Siacoin (SIA) can maximize your GPU mining efficiency. While Windows setups are straightforward, configuring Claymore 9.0 for dual mining on ethOS requires precise edits to claymore.stub.conf and local.conf. Below’s a streamlined guide based on community-tested solutions.

Step-by-Step Configuration

1. Edit claymore.stub.conf

Locate the file in ethOS and uncomment/modify these lines:
plaintext
-mode 0
-dcoin sia # Specify SIA as the secondary coin
-dpool stratum+tcp://sia-eu1.nanopool.org:7777 # SIA pool URL
-dwal YourSiaWalletAddress.YourWorkerName # Add a worker name after the wallet
-dpsw x # Pool password (usually 'x')
👉 Optimize your mining setup with these pro tips

2. Configure local.conf

Ensure ETH mining settings are active:
plaintext
globalminer claymore
stratumproxy enabled
proxywallet YourEthWalletAddress
proxypool1 eth-us.dwarfpool.com:8008 # Primary ETH pool
flags --cl-global-work 8192 --farm-recheck 200

3. Launch Mining

Restart the miner via ethOS command:
bash
minestart

Troubleshooting Common Issues

Problem Solution
Rejected SIA shares Verify -dwal format (e.g., Address.WorkerName for Nanopool).
ETH hashrate not reported Keep -ewal as WALLET in claymore.stub.conf; only set the wallet in local.conf.
High GPU temperatures Adjust maxgputemp 85 and globalfan 85 in local.conf.

Performance Optimization

  • GPU Settings: For RX 470/580, use:
    plaintext
    globalcore 1200
    globalmem 2250
    globalpowertune 4
  • Dual Mining Intensity: Reduce -dcri (e.g., -dcri 20) to balance ETH/SIA hashrates.

FAQ

1. Can I dual mine ETH and Decred (DCR) instead?

Yes! Replace -dcoin sia with -dcoin dcr and update pool/wallet details.

2. Why are my SIA balances not updating?

Some pools (e.g., Nanopool) require a worker name appended to your wallet address (e.g., Address.Worker).

3. How do I check miner logs?

Use show miner in ethOS terminal or add -logfile noappend.txt to prevent redundant logs.

Final Notes

  • ethOS Limitations: The OS doesn’t officially support dual mining, but community workarounds work.
  • Profitability: Monitor via WhatToMine and adjust coins as needed.

By following these steps, you can efficiently dual mine ETH and SIA on ethOS. For further tuning, join forums like Bitcointalk to share insights.

Happy Mining! 🚀
