How to mine Ergo (ERG)? What are the best GPUs and settings for Autolykos2?

Understanding Ergo Mining Fundamentals

1. Ergo operates on the Autolykos2 proof-of-work consensus algorithm, designed to resist ASIC dominance while maintaining GPU-friendliness and memory-hard characteristics.

2. Autolykos2 requires approximately 4.5 GB of VRAM per mining instance, making it accessible to mid-tier consumer graphics cards without demanding extreme memory bandwidth.

3. Mining involves solving cryptographic puzzles tied to Ergo’s UTXO-based ledger, where each block reward is currently set at 24 ERG, halving every 2,160,000 blocks (~4 years).

4. Miners must run a full Ergo node or connect to a trusted one via RPC to submit shares and validate block templates accurately.

5. Difficulty adjustments occur every 60 blocks (roughly every 90 minutes), ensuring consistent block times around 120 seconds regardless of network hash rate fluctuations.

Top Performing GPUs for Autolykos2

1. NVIDIA RTX 3080 (10GB) delivers ~145–155 MH/s with optimized memory timings and undervolted core clocks, offering the best performance-per-watt ratio among widely available models.

2. AMD RX 6700 XT (12GB) achieves ~120–130 MH/s and benefits from native OpenCL support in most Ergo miners, though driver stability varies across Linux distributions.

3. NVIDIA RTX 4070 Ti (12GB) reaches ~160–168 MH/s under aggressive memory overclocking but exhibits higher thermal density, requiring robust case airflow.

4. AMD RX 6800 (16GB) sustains ~140 MH/s and shows strong consistency over extended sessions due to its wide memory bus and efficient cooling design.

5. Legacy cards like the GTX 1070 (8GB) remain viable at ~65 MH/s but suffer from declining driver support and higher power consumption per MH/s.

Optimal Mining Software and Configuration

1. T-Rex Miner v24.9+ supports Autolykos2 natively on Windows and Linux, includes automatic memory tuning, and provides real-time DAG generation metrics.

2. TeamRedMiner 0.9.11 remains preferred for AMD GPUs, especially on Ubuntu 22.04 LTS, with configurable L2 cache hints that reduce stale share rates by up to 18%.

3. Memory clock offsets between +800 MHz and +1100 MHz yield diminishing returns beyond +950 MHz on GDDR6X chips, while GDDR6 cards peak near +1050 MHz with stable timings.

4. Core voltage reduction to 750–820 mV on NVIDIA cards maintains hash rate while cutting power draw by 15–22%, verified through wattmeter measurements across 72-hour stress tests.

5. DAG file generation uses system RAM first; allocating ≥16 GB of host RAM prevents swapping delays during epoch transitions occurring every 61,440 blocks (~12.8 days).

Pool Selection and Connection Parameters

1. 2miners.com/ergo offers PPLNS payout with 0.9% fee, low minimum payout threshold (0.1 ERG), and supports stratum+tcp and stratum+ssl protocols.

2. Herominers.com provides merged mining options for ERG+ETH dual-mining configurations, though Ethash interference may reduce overall Autolykos2 efficiency by 3–5%.

3. Pool-side difficulty should be set between 100 and 200 to balance share submission frequency and upstream validation latency, avoiding excessive rejected shares.

4. SSL-enabled connections require certificate pinning in miner config files to prevent man-in-the-middle tampering, especially critical when using public Wi-Fi or shared hosting environments.

5. Failover pool configuration must use geographically proximate endpoints—e.g., eu.2miners.com followed by us.2miners.com—to minimize connection handshaking overhead during primary pool outages.

Frequently Asked Questions

Q: Does Ergo mining require constant DAG regeneration?A: No. The DAG is generated once per epoch and reused until the next epoch begins. Epochs last 61,440 blocks, so regeneration occurs roughly every 12.8 days.

Q: Can I mine Ergo using integrated graphics?A: Integrated GPUs lack sufficient VRAM and compute units to meet Autolykos2’s memory-hard requirements. Minimum viable discrete GPU is the GTX 1050 Ti (4GB), though not recommended for profitability.

Q: Is CPU mining feasible for Ergo?A: CPU mining is intentionally disabled in all mainstream Autolykos2 implementations. The algorithm mandates GPU-bound memory access patterns that cannot be efficiently replicated on x86-64 cores.

Q: Do I need to hold ERG tokens to begin mining?A: No token holding is required. A wallet address is sufficient to receive payouts. Wallets such as Yoroi, Ergo App, or CLI-based ergo-wallet can generate valid receiving addresses immediately.
