Merged-mining Litecoin + Dogecoin : guide complet avec l’Antminer L9 (15G/16G/16.5G/17G)

Merged mining LTC + DOGE allows mining Litecoin (LTC) while receiving Dogecoin (DOGE) rewards without increasing electricity consumption. With the series Antminer L9 (Scrypt), you maximize your earnings using the same computing power. Here is the Minent.fr guide for configure, to optimise And follow your results.

Why do merged mining of LTC + DOGE?

• Additional income in DOGE for the same consumption (same J/MH).
• Risk pooling : exposure to two assets (LTC & DOGE).
• High liquidity : LTC/DOGE/USDT pairs are easy to convert.

Technical reminders (Series) L9)

Indicative values (±3–5%) depending on batch/firmware and environment.

Prerequisites

• Antminer L9 (up-to-date firmware) and 200–240 V power supply.
• Compte sur un pool Scrypt compatible merged-mining LTC + DOGE.
• Receiving address(es) LTC and/or DOGE (or a pool account with auto-payout).
• Stable Ethernet connection (avoid Wi-Fi).

Step-by-step configuration (Antminer interface)

1. Log in to the interface L9 (local IP) → Miner Configuration.
2. In the tab Pooladd 3 endpoints from the same pool (primary URL + 2 secondary URLs) for automatic failover.
3. Provide information Worker (format username.worker) and a password (often "x" or parametric depending on the pool).
4. Activate the merged mining pool side (some enable it by default; others require a toggle or sub-account configuration).
5. Save, restart the miner if necessary, then check the tab Miner Status (accept/reject shares, temp, frequency).

Note : The exact configuration depends on your pool. Refer to its documentation for the URL and parameters (Scrypt ports, PPS/PPLNS mode, LTC/DOGE payment thresholds).

Choosing your pool: key criteria

• Merged-mining compatibility LTC + DOGE (enabled by default or option).
• Remuneration : PPS+, FPPS, PPLNS (PPS+ = stable, PPLNS = more variable but less cost).
• Costs (0.5–3%) and payment thresholds for LTC and DOGE.
• EU Servers (low latency), reliability and clear stats interface.

Optimisation & tuning

Airflow and temperature

• Maintain fresh air intake (< 30 °C) and efficient extraction.
• Clean filters/fans to prevent heat-related hashrate loss.

Firmware and stability

• Stay on a stable firmware (official) before experimenting with undervolt.
• Keep an eye on the acceptance rate (rejections < 2–3%).

Undervolt / underclock (optional)

• Objective : reduce J/MH if your electricity is expensive (≥ €0.15/kWh).
• Proceed in small steps (-1 to -3%) and check the stability for 24–48 h.

Revenue tracking (KPIs to monitor)

• Effective hashrate pool vs local (ideally a difference of < 3%).
• Shares rejected (rejected) and stale (network latency).
• LTC Payouts And DOGE, schedule and thresholds.
• Energy cost : (W/1000) × kWh price × 24 h.

ROI: a simple example

For a L9 16.5G (16.5 GH/s, ~3400 W, ~0.33 J/MH): Daily earnings = (LTC earnings) + (DOGE bonus in merged mining). The electricity cost = (3.4 kW × kWh price × 24). If your kWh cost is high (≥ €0.15), theundervolt can improve ROI by reducing consumption by 5–10% at the cost of 1–3% hashrate.

Minent.fr Best Practices

• Register 2–3 pools in back (automatic switching if the primary fails).
• Use a inverter/surge protector to protect the PSU.
• Check the grounding and the cable cross-section.
• Settle some alerts (temperature, hashrate, offline) via the pool dashboard.

FAQ rapide

Does merged mining consume more resources?
No: consumption remains the same, you make better use of each MH/s.

Can I be paid solely in LTC?
Depending on the pool, yes (auto-conversion). Otherwise, you receive LTC + DOGE separately.

Is DOGE still "merged" with LTC?
Major Scrypt pools offer merged mining of LTC/DOGE. Check your pool's page.
