The GTX 1080’s Ethereum (Ethash) mining hashrate varies․
Table of contents
Expected Hashrate
A GTX 1080 can achieve 30-40 MH/s․ With proper configuration, it can reach 40 MH/s․ The 1080 Ti can reach 50 MH/s․
Ethereum Classic (ETC) using Etchash can achieve 51․20 MH/s on a 1080 Ti․
Factors Affecting Speed
- Overclocking: Optimizing core and memory clocks improves hashrate․
- Algorithm: Ethash is the primary algorithm for Ethereum․
- Software: Mining software impacts performance․
Optimizing Your GTX 1080 for Ethereum Mining
To maximize your GTX 1080’s Ethereum mining speed, consider the following steps:
Driver Installation and Updates
Ensure you have the latest NVIDIA drivers installed․ These drivers often include performance optimizations that can benefit mining operations․ Check the NVIDIA website for the most recent version compatible with your operating system․
Overclocking Settings
Careful overclocking can significantly improve your hashrate․ However, it’s crucial to monitor temperatures and stability․ Here’s a general approach:
- Memory Clock: Start by increasing the memory clock in small increments (e․g․, +50 MHz) and testing for stability․ Gradually increase until you find the optimal point before artifacts or crashes occur․
- Core Clock: Adjust the core clock in smaller increments․ Be cautious, as excessive core overclocking can lead to instability and reduced efficiency․
- Power Limit: Adjust the power limit to allow the card to draw more power for increased performance․ However, be mindful of your power supply and cooling capabilities․
Tools like MSI Afterburner or EVGA Precision X1 can be used to adjust these settings․
Mining Software Selection
Choose a mining software that is optimized for NVIDIA GPUs and Ethereum mining․ Popular options include:
- T-Rex Miner: Known for its performance and efficiency on NVIDIA cards․
- PhoenixMiner: Another solid choice with good hashrate and stability․
- NBminer: A versatile miner supporting various algorithms․
Experiment with different miners to find the one that yields the best results for your specific setup․
Cooling Solutions
Adequate cooling is essential to prevent overheating and maintain stable performance․ Ensure your GTX 1080 has sufficient cooling, whether it’s the stock cooler or an aftermarket solution․ Consider improving case airflow to dissipate heat effectively․
Ethereum Difficulty and DAG Size
The Ethereum network difficulty and DAG (Directed Acyclic Graph) size affect mining performance․ As the DAG size increases over time, older GPUs with limited VRAM may experience performance degradation․ The GTX 1080, with its 8GB of VRAM, is currently sufficient, but this is something to monitor in the long term․
Is Ethereum Mining Still Profitable?
As of today, February 5, 2026, Ethereum has transitioned to Proof-of-Stake (PoS)․ This transition, known as “The Merge,” has rendered traditional GPU mining of Ethereum obsolete․ While the GTX 1080 is no longer suitable for mining Ethereum, it can still be used to mine other cryptocurrencies that utilize Proof-of-Work (PoW) algorithms․ However, their profitability compared to more modern GPUs is likely to be significantly lower․
Alternative Mining Options
If you’re looking for alternative cryptocurrencies to mine with your GTX 1080, consider researching options like:
- Ethereum Classic (ETC): While originally Ethereum, it continues as a Proof-of-Work chain․
- Ravencoin (RVN): Uses the KawPow algorithm․
- Conflux (CFX): Uses the Octopus algorithm․
Remember to always research the profitability and power consumption of different cryptocurrencies before committing to mining them․
