OKEX矿池 ETH/ETC Mining Common Questions

·

Mining Ethereum (ETH) and Ethereum Classic (ETC) through a reliable mining pool like OKX (formerly OKEX) can significantly enhance your mining efficiency and payout stability. However, many miners—especially beginners—encounter technical hurdles that disrupt operations. This guide addresses the most common issues faced when mining ETH and ETC via the OKX mining pool, offering clear solutions to help you maintain uninterrupted mining performance.

Whether you're using PhoenixMiner, Claymore, or bMiner, understanding how to troubleshoot connectivity, hardware compatibility, and software conflicts is essential. We’ll walk you through error messages, system requirements, and best practices for smooth mining operations.

Common Connection Errors and Solutions

One of the most frequent problems miners face is an inability to connect to the mining pool server. This typically results in errors related to DNS resolution or network timeouts.

PhoenixMiner Connection Issues

When using PhoenixMiner, you might see the following red error message:

Eth: Can't resolve host stratum.okpool.me:3333 – The requested name is valid, but no data of the requested type was found

This indicates that your miner cannot reach the stratum server due to a DNS resolution failure. Possible causes include:

Claymore Miner Errors

Claymore users may encounter these error messages:

Cannot resolve 'stratum.okpool.me'
ETH: Stratum – Cannot connect to stratum.okpool.me:3333
ETH: Stratum – Fail to connect, retry in 20 sec...

These indicate the same core issue: the software fails to resolve the mining pool domain. To fix this:

bMiner Connection Failures

With bMiner, you may see:

bMiner: connect failed due to (garbled text), retrying in 5 seconds.

Garbled error output often points to encoding issues or corrupted downloads. Reinstall the latest version from a trusted source and ensure your system locale is set to English (United States) to avoid display errors.

No GPU Detected: Driver and Hardware Requirements

Another common issue arises when the mining software fails to detect your graphics card.

PhoenixMiner Behavior

If no GPU is detected or drivers are missing, PhoenixMiner may launch and immediately close without displaying detailed logs—a “flash exit” behavior.

Claymore Error Messages

Claymore will display one of the following:

AMD OpenCL platform not found
No NVIDIA CUDA GPUs detected
No AMD OPENCL or NVIDIA CUDA GPUs found, exit

These messages mean the miner cannot interface with your GPU due to:

bMiner Fatal Errors

bMiner may show repeated logs like:

[FATA] [2019-08-19T08:27:50+08:00] Failed to initialize the CUDA platform: CudaError: Failed to load nvml.dll 126
[WARN] [2019-08-19T08:27:50+08:00] Miner died! It will be restarted soon…

Error 126 usually means nvml.dll is missing or corrupted—part of the NVIDIA driver package. Reinstalling the latest NVIDIA drivers typically resolves this.

Minimum GPU Memory Requirement for ETH Mining

A critical hardware consideration is video memory (VRAM). To mine Ethereum effectively:

To check your VRAM:

  1. Open Device Manager
  2. Expand Display adapters
  3. Right-click your GPU → Properties
  4. Go to Adapter tab → View total available graphics memory

Alternatively, search your GPU model online (e.g., “RTX 3060 VRAM”) to confirm specifications.

While ETC mining also uses GPU power, its DAG file is smaller, so some 2GB cards may still function—but performance will be limited.

Antivirus False Positives: Why Miners Are Flagged

It's common for mining software such as PhoenixMiner, Claymore, or bMiner to be flagged by Windows Defender or third-party antivirus programs.

This happens because:

However, legitimate mining tools are not viruses when downloaded from official sources.

How to Resolve False Positives:

Always verify file integrity using checksums if available.

Frequently Asked Questions (FAQ)

Q: Can I mine ETH with a 2GB GPU?
A: No. Ethereum mining requires at least 3GB of VRAM due to the growing DAG file size. GPUs with 2GB will fail during initialization.

Q: Why does my miner keep disconnecting every few minutes?
A: Frequent disconnections can stem from unstable internet, router timeouts, or firewall interference. Try switching DNS servers and opening port 3333 on your router.

Q: Is it safe to disable antivirus for mining?
A: Only if you trust the miner source. Instead of fully disabling antivirus, add the miner directory to the exclusion list for safer operation.

Q: What should I do if ‘nvml.dll’ is missing?
A: Reinstall the latest NVIDIA graphics driver. This file is part of the driver suite and will be restored upon clean installation.

Q: Can I use OKX矿池 for both ETH and ETC?
A: Yes. The OKX mining pool supports multiple algorithms and cryptocurrencies, including ETH and ETC, allowing flexible multi-chain mining strategies.

Q: Does OKX charge fees for pool mining?
A: Pool mining typically involves a small maintenance fee (usually 1–2%) deducted from rewards. Check the official OKX mining portal for current rates.

Final Tips for Stable Mining Operations
