How to Mine ETH and Zcash on Claymore

Learning how to mine ETH and Zcash on Claymore was a rite of passage for many early cryptocurrency enthusiasts. Claymore’s miners were once the gold standard for performance and versatility in the GPU mining community. This guide provides a detailed technical breakdown of how these miners operated, the specific configurations required for success, and the transition of these assets into the current market landscape.

1. Introduction to Claymore Mining Software

Claymore’s mining software, developed by the developer known as "Claymore," became iconic during the GPU mining booms between 2016 and 2021. Known for its high-performance optimization, it pioneered features like "Dual Mining," which allowed users to mine Ethereum (ETH) and a secondary coin simultaneously without significantly impacting the primary hashrate.

The software suite primarily consisted of two distinct programs: the Claymore Dual Ethereum GPU Miner for Ethash-based coins and the Claymore ZCash AMD GPU Miner for Equihash-based privacy coins. According to historical community data from forums like Bitcointalk, Claymore miners often delivered a 3-5% performance boost over standard open-source alternatives due to custom assembler kernels.

2. Mining Ethereum (ETH) via Claymore Dual Miner

2.1 Hardware Requirements and Driver Setup

To successfully run the Claymore Dual Miner, specific hardware parameters had to be met. Ethereum mining utilized the Ethash algorithm, which is highly memory-intensive. By 2021, the DAG (Directed Acyclic Graph) file size surpassed 4GB, making GPUs with at least 6GB or 8GB of VRAM the industry standard for stability.

For AMD users, legacy drivers such as Crimson 15.12 were often cited as the most stable for Claymore software. For NVIDIA users, CUDA-optimized drivers were essential. Modern traders who once used this hardware have now shifted toward platforms like Bitget, which supports over 1,300+ assets, providing a much higher yield potential than legacy mining rigs.

2.2 Configuration and Batch (.bat) File Setup

The core of learning how to mine ETH and Zcash on Claymore lies in the command-line interface. A standard

file for Ethereum mining followed this structure:

Key parameters included:
- -epool: The stratum address for your chosen mining pool (e.g., Ethermine or F2Pool).
- -ewal: Your Ethereum wallet address.
- -esm: Ethereum Stratum mode (usually set to 0 for default).
- -epsw: Password for the pool, typically set to "x".

2.3 Understanding "Dual Mining" Mode

One of Claymore's most famous features was the ability to mine a second coin (like Decred or SiaCoin) alongside ETH. This was possible because ETH mining is memory-bound, leaving the GPU core's processing power underutilized. Claymore filled this gap, increasing the profitability of the hardware by up to 10-15% during peak periods.

3. Mining Zcash (ZEC) with Claymore’s Equihash Miner

3.1 Claymore’s ZCash AMD GPU Miner vs. Dual Miner

It is important to clarify that Zcash uses the Equihash algorithm. While the Dual Miner focused on Ethereum, Claymore released a separate, specialized miner for Zcash. Unlike ETH mining, Zcash mining was extremely sensitive to core clock speeds and required efficient cooling due to the heavy computational load on the GPU core.

3.2 Key Command Line Options for Zcash

The configuration for Zcash was slightly different, using the

file. A typical setup would look like this:

The -i parameter (intensity) was critical here; setting it too high could crash the system, while setting it too low would result in a sub-optimal hashrate. Today, Zcash mining is largely dominated by ASIC (Application-Specific Integrated Circuit) hardware, making GPU mining with Claymore software obsolete for the ZEC network.

4. Technical Comparison: ETH vs. ZEC Mining Performance

The following table illustrates the typical performance metrics for a mid-range GPU (e.g., Radeon RX 580) using Claymore software during the PoW era.

Average Hashrate	28 - 31 MH/s	300 - 330 Sol/s
Primary Resource	Video Memory (VRAM)	Core Processing Power
Optimal Temp	60°C - 70°C	65°C - 75°C
Power Draw	~120W	~150W

This data confirms that Zcash mining was generally more demanding on the hardware's power supply and cooling systems compared to Ethereum mining. As the industry evolved, many miners transitioned from maintaining hardware to direct asset acquisition on Bitget, which offers a much lower barrier to entry for acquiring these top-tier assets.

5. Advanced Tuning and Developer Fees

Claymore miners included an "ASM mode" (enabled with

) that allowed for further fine-tuning of AMD cards. Users often adjusted the -dcri parameter to find the perfect balance between the primary and secondary coins during dual mining.

It is worth noting that Claymore software carried a developer fee. Typically, the miner would mine for the developer for 1 to 2 minutes every hour (approx. 1-2% of total hashrate). While a "-nofee" flag existed, using it would often disable the optimized assembler kernels, resulting in a net loss of performance. This transparent fee model funded the continuous updates that kept Claymore at the top of the mining charts for years.

6. The Shift to Proof-of-Stake and Modern Alternatives

The era of mining Ethereum ended with "The Merge" in September 2022, when Ethereum officially transitioned to Proof-of-Stake (PoS). This change rendered Claymore ETH mining completely obsolete. While Zcash still uses Proof-of-Work, the difficulty has increased to the point where GPU mining is no longer viable for individual hobbyists.

For those looking to participate in the growth of ETH and ZEC today, the focus has shifted from hardware to high-liquidity trading and staking. Bitget stands out as a leading global exchange, offering a secure environment for these activities. With a Protection Fund exceeding $300 million and a regulatory presence across various jurisdictions, Bitget provides the reliability that the old mining pools often lacked.

Why Bitget is the Top Choice for Former Miners:
- Asset Variety: Support for 1,300+ coins, including ETH and ZEC forks.
- Competitive Fees: Spot maker/taker fees at just 0.1%, with further discounts of up to 20% when using BGB.
- Institutional Grade Security: Verified Proof of Reserves and a robust Protection Fund ensure user assets are always safe.

7. Troubleshooting Common Claymore Errors

Even the best software encountered issues. Common errors included:
- "Out of Memory": Usually caused by an insufficient Windows Page File. Miners were advised to set virtual memory to at least 16GB.
- "Socket Closed": Often a result of firewall settings or an unstable pool connection.
- "GPU Hang": Typically caused by over-aggressive overclocking or failing hardware.
