Frequently Asked Questions About NVIDIA GPU Mining

Which NVIDIA GPU offers the best hash rate for mining?

The RTX 3090 typically delivers the highest raw hash rate among consumer NVIDIA cards, achieving around 120 MH/s on Ethash. However, the RTX 3080 and RTX 3070 offer better value when considering cost per megahash. Mid-range cards like the RTX 3060 Ti and RTX 2070 Super also provide strong performance for their price, especially if you can find them used. The “best” card depends on your budget, electricity cost, and target coin.

Can I mine on NVIDIA cards that have the LHR (Lite Hash Rate) limiter?

Yes, many LHR cards can be partially unlocked using custom drivers or mining software that bypasses the limiter. Most modern miners like T-Rex and NBMiner include LHR unlock features, typically recovering 70–100% of the original hash rate on ETH-based algorithms. However, non-LHR cards (e.g., RTX 3060 v1, RTX 3080/3090 FE early batches) are preferred if available.

What is the optimal overclock setting for NVIDIA mining cards?

Optimal settings vary by card and algorithm. A typical starting point for Ethash on RTX 30 series is: core clock locked around 1200–1300 MHz, memory clock +1000–1500 MHz (depending on thermal limits), power limit 70–80%. For KawPow (Ravencoin), higher core clocks (1500–1700 MHz) are often beneficial. We recommend incremental testing with tools like MSI Afterburner while monitoring hash rate and temperature.

How many NVIDIA GPUs can I put in a single mining rig?

A standard mining motherboard with six to eight PCIe slots can support up to 8 GPUs when using risers and appropriate power supply. With dedicated mining motherboards supporting 12+ slots, you can run 10–12 cards if your power supply and cooling can handle the load. It’s important to ensure your motherboard BIOS is set to “4G decoding” and above-4G support is enabled for stability.

Is NVIDIA GPU mining still profitable in 2022?

Profitability depends on several factors: coin price, network difficulty, electricity rate, and your hardware’s efficiency. Many mid-range and high-end NVIDIA cards can still generate a positive daily return after electricity costs, especially if you have access to low electricity rates (under $0.10/kWh). It is essential to use a mining calculator and regularly review your profitability as market conditions change.
