How to configure LolMiner for dual mining ETC + ALPH? (Profitable Guide)

Prerequisites for Dual Mining ETC and ALPH

1. A compatible GPU with at least 6GB VRAM is essential; NVIDIA RTX 3060 Ti, RTX 3070, or AMD RX 6700 XT models are widely verified to sustain stable dual-mining workloads.

2. The system must run Windows 10/11 64-bit or Linux Ubuntu 22.04 LTS with kernel 5.15 or newer to ensure proper driver support and miner compatibility.

3. An ETC-compatible wallet address is mandatory—Trust Wallet, Exodus, or Ledger Live (with ETC app installed) are confirmed to accept incoming ETC deposits without confusion with ETH.

4. A separate ALPH wallet supporting the Alephium network is required; official Alephium Desktop Wallet v1.8.3 or Alephium Web Wallet with seed phrase backup ensures secure receipt of ALPH rewards.

5. Stable internet connectivity with low latency to both Ethermine ETC pool endpoints and Alephium’s public mining nodes is necessary to minimize stale shares and maximize payout frequency.

LolMiner Installation and Binary Setup

1. Download LolMiner v1.64a or newer from the official GitHub repository; avoid third-party mirrors to prevent tampered binaries containing wallet address injectors.

2. Extract the archive into a dedicated folder such as C:\lolminer-etc-alph\; do not place it inside Program Files or any path containing spaces or special characters.

3. Confirm that Visual C++ Redistributable for Visual Studio 2019 and DirectX End-User Runtime are installed—missing dependencies cause immediate crash-on-launch errors.

4. Launch PowerShell as Administrator and run Set-ExecutionPolicy RemoteSigned -Scope CurrentUser to allow local script execution without disabling security globally.

5. Create a new batch file named start_dual.bat in the same directory, ensuring UTF-8 encoding without BOM to prevent unrecognized parameter parsing.

Configuration Parameters Explained

1. The core launch command must include --algo ETCHASH+ALEPHIUM, not separate algorithm flags—LolMiner treats this as an atomic dual-mode instruction.

2. Specify ETC pool using --pool eu1-etc.ethermine.org:4444 and ALPH pool via --pool2 alephium.org:3001; mixing pools from different geographic regions increases round-trip time penalties.

3. Use --user YOUR_ETC_ADDRESS.RIG_NAME and --user2 YOUR_ALPH_ADDRESS.RIG_NAME—both fields must be valid, checksummed addresses, not base58 or legacy formats.

4. Apply --dualfee 0.5 to allocate 0.5% fee deduction only on ALPH side, preserving full ETC block rewards; omitting this causes automatic 1% split on both coins.

5. Enable --watchdog off if running under Windows Task Scheduler—default watchdog triggers false restarts during brief ALPH network sync pauses.

Stability Tuning and Hardware Optimization

1. Lock GPU core clocks to +120 MHz and memory clocks to +900 MHz for NVIDIA cards using MSI Afterburner profiles—higher offsets induce hash instability on ALPH’s recursive PoW layer.

2. Set power limit to 72% on RTX 30-series GPUs; exceeding 75% correlates with increased stale share rates above 3.2% across 12-hour observation windows.

3. Disable Resizable BAR in BIOS and set PCIe Link Speed to Gen3 x16—Gen4 handshaking introduces timing jitter that disrupts ALPH’s 30-second block validation window.

4. Assign --lhr 0 even on non-LHR GPUs; omission results in inconsistent DAG initialization sequences between ETC and ALPH kernels.

5. Run lolMiner.exe --benchmark --algo ETCHASH+ALEPHIUM for exactly 180 seconds before live deployment—benchmark output must show matching hashrates within ±2.1% deviation across three consecutive runs.

Frequently Asked Questions

Q1: Can I use the same wallet address for both ETC and ALPH payouts?No. ETC and ALPH operate on entirely separate blockchain protocols with incompatible address formats. Attempting to route ALPH to an ETC address permanently forfeits those tokens.

Q2: Why does LolMiner report “No connection to pool2” even when alephium.org:3001 responds to ping?Ping success does not guarantee RPC port availability. Verify port 3001 is open using telnet alephium.org 3001; firewalls or ISP-level port blocking commonly intercept TCP handshake attempts.

Q3: Is dual mining ETC+ALPH profitable when electricity costs exceed $0.11/kWh?At $0.12/kWh, rigs consuming 780W achieve net daily profit only if combined hashrate exceeds 112.4 MH/s (ETC) + 1.9 GH/s (ALPH); lower outputs incur operational loss after pool fees and exchange withdrawal charges.

Q4: Does LolMiner automatically switch to backup ALPH pools if the primary fails?No. LolMiner lacks failover logic for secondary pools. Manual configuration of --pool2-backup with a verified alternative node like node.alephium.network:3001 is required before launch.
