Mining Ethereum PoW (ETHW) remains a viable option for GPU miners seeking profitable alternatives in the post-merge crypto landscape. With the transition of Ethereum to Proof-of-Stake, Ethereum PoW emerged as a community-driven fork that continues to support GPU-based mining using the Ethash algorithm. This guide explores the key aspects of ETHW mining, including hardware requirements, profitability calculation, pool vs. solo strategies, and practical setup examples—optimized for both beginners and experienced miners.
Understanding the Ethereum PoW DAG File Size
A critical factor in ETHW mining is the DAG (Directed Acyclic Graph) file, which is generated and loaded into GPU memory during mining operations. The DAG grows in size over time due to the nature of the Ethash algorithm, directly impacting which GPUs can effectively mine ETHW.
As of now, the DAG size for Ethereum PoW is approximately 6.772 GB. This means only GPUs with at least 7 GB of VRAM or more are capable of mining ETHW efficiently.
Important Note: While this threshold applies accurately to Linux systems, Windows users should account for additional GPU memory usage by the operating system and display drivers. As a result, Windows-based rigs may struggle or fail to mine ETHW even with 7 GB GPUs, due to reduced available memory for the DAG.

Hardware Requirements for Mining ETHW
To get started with ETHW mining, you’ll need appropriate hardware capable of handling the growing DAG size and maintaining stable hash rates.
Compatible Devices:
- NVIDIA and AMD GPUs are fully supported.
Minimum 7 GB VRAM is required—ideal models include:
- NVIDIA RTX 3070, 3080, 3090
- AMD RX 6700 XT, 6800, 6800 XT, 6900 XT
- Older cards like the GTX 1080 Ti (11 GB) or RX 5700 XT (8 GB) may still perform well if properly tuned.
Both GPU and ASIC miners can participate in the network, though GPUs dominate due to accessibility and flexibility.
Additionally, platforms such as Nicehash and MiningRigRentals allow users to rent hash power for short-term mining experiments or scaling operations without owning physical hardware.
Pool Mining vs. Solo Mining: What’s the Difference?
Choosing between pool mining and solo mining significantly affects your reward structure, consistency, and risk level.
| Aspect | Pool Mining | Solo Mining |
|---|---|---|
| Collaboration | You work with other miners | You mine independently |
| Reward Frequency | Frequent, smaller payouts based on contribution | Rare, full-block rewards only when you find a block |
| Income Stability | High – consistent daily earnings | Low – highly dependent on luck and hash rate |
| Best For | Beginners and mid-level miners | Experienced miners with large hash power |
⚠️ Recommendation: Only consider solo mining if your rig has enough hash rate to find 2–3 blocks per day. Otherwise, pool mining offers far more predictable returns.

Frequently Asked Questions
Q: Can I mine ETHW with a 6 GB GPU?
A: No. Due to the current DAG size (~6.772 GB), GPUs with less than 7 GB VRAM cannot load the full DAG file and will fail during mining initialization.
Q: Why does Windows prevent some 7 GB GPUs from mining?
A: Windows reserves part of the GPU memory for system processes (e.g., desktop composition), leaving insufficient space for the DAG. Linux typically provides better memory efficiency for mining rigs.
Q: Is ASIC mining profitable for ETHW?
A: While ASICs offer high hash rates, GPU mining remains dominant due to broader availability and lower entry barriers. However, ASICs can be cost-effective at scale if power costs are low.
Q: How often does the DAG size increase?
A: The DAG grows roughly every 100,000 blocks (about every 3–4 days). Plan upgrades accordingly if you're near the VRAM threshold.
Ethereum PoW Solo Mining Profitability Calculator
While we don't display live tables here, you can estimate solo mining profitability using these core metrics:
- Your Hash Rate (MH/s): Total performance of your mining rig
- Network Difficulty: Current challenge level to find a block
- Block Reward: Fixed at 2 ETHW per block
- Daily Blocks Mined Network-Wide: Typically around 7,150 blocks/day
- Your Expected Blocks Per Day:
(Your Hash Rate / Network Hash Rate) × Daily Blocks
For example:
- If the network hash rate is 5 TH/s and your rig delivers 100 MH/s:
- Your share:
(0.1 / 5000) = 0.002% - Expected blocks per day:
7,150 × 0.00002 = ~0.143 blocks/day - Daily income:
0.143 × 2 ETHW = ~0.286 ETHW
This illustrates why solo mining requires substantial hash power for reliable returns.
What Is the Best ETHW Solo Mining Strategy?
Professional miners use a dynamic approach:
- Monitor real-time network difficulty trends
- Switch between solo and pool mining based on statistical probability
- Rent additional hash power via platforms like Nicehash during favorable difficulty dips
Success isn't just about luck—it's about data-driven decisions and timing.
🔍 Pro Tip: Use mining calculators to simulate outcomes before switching modes. Track metrics like time-to-find-a-block and expected ROI weekly.
Top Ethereum PoW Mining Pools
Reliable pools ensure consistent payouts and low downtime. Some popular options include:
- 2Miners
- Flypool
- Nanopool
- MiningPoolHub
These pools typically use PPLNS (Pay Per Last N Shares) reward systems, encouraging long-term participation.
