How to identify mining cards? Analysis and practical guide of hot topics across the Internet
Recently, with the fluctuations in the cryptocurrency market, a large number of mining cards have flowed into the second-hand market. How to identify mining cards has become the focus of hardware enthusiasts and ordinary consumers. This article will combine hot topics and structured data in the past 10 days on the Internet to provide you with a detailed guide to identify mining cards.
1. Characteristics and risks of mining cards
Mining cards refer to graphics cards that have been used for cryptocurrency mining for a long time. Due to long-term high-load operation, their lifespan and performance may be seriously damaged. The following are typical characteristics of mining cards:
| Features | Description |
|---|---|
| Cosmetic wear | The radiator is heavily dusted, the fan bearings are worn, and the PCB board may have oxidation marks. |
| BIOS modification | Miners may flash specific BIOS to increase computing power, causing the graphics card to be unable to update the driver normally. |
| Core yellowing | Long-term high-temperature operation may cause the GPU core color to turn yellow |
| The interface is loose | Frequent plugging and unplugging may cause poor contact of the HDMI/DP interface |
2. Practical methods to identify mining cards
The following are several methods of identifying mining cards that are hotly discussed on the Internet, combining hardware detection and software tools:
| method | Operation steps | effectiveness |
|---|---|---|
| Check SN code | Check the factory date through the SN code of the graphics card. If it is much earlier than the purchase time and there is no warranty record, it may be a mining card. | high |
| GPU-Z detection | Run GPU-Z to check whether the core frequency and video memory frequency are abnormal. Mining cards usually have traces of overclocking. | Middle to high |
| stress test | Use FurMark to bake the machine for more than 15 minutes and observe the temperature curve and whether there is any blurry screen. | high |
| Disassembly and inspection | Check whether the heat dissipation silicone grease has dried up and whether the capacitor has bulges. | Extremely high (but may void warranty) |
3. Statistics on recent popular mining card models
According to data from major forums and e-commerce platforms, the following models are the hardest hit areas for mining trucks (data from October 2023):
| Graphics card model | Proportion of mining cards | Typical mining time |
|---|---|---|
| NVIDIA RTX 3060Ti | about 65% | 1-2 years |
| AMD RX 580 | More than 80% | More than 3 years |
| NVIDIA GTX 1660 Super | about 50% | 1-1.5 years |
| AMD RX 5700 XT | about 70% | 2-3 years |
4. Purchasing Suggestions and Anti-Pit Guidelines
1.Give priority to those with official warrantygraphics card, reject vague descriptions such as "work package" and "disassembled card";
2.Request sellers to provide real-life videos, showing the normal operating status of the graphics card;
3.Avoid the low price trap, the price is more than 30% lower than the market price with a high probability of being a mining card;
4.Consider purchasing newly released models, such as RTX 40 series or RX 7000 series, the probability of mining cards is low.
5. Summary
Identifying mining cards requires comprehensive visual inspection, software testing and market analysis. After the recent conversion of the cryptocurrency ETH to a POS mechanism, a large number of mining cards have flooded into the market, and consumers need to be more cautious. It is recommended to purchase through formal channels and keep complete transaction documents to protect your own rights and interests.
