Signs to identify “coin card”

Signs to identify “coin card”


For us gamers, there is certainly nothing happier than going to the store and shouting “Build yourself a full system configuration for every game”. However, not everyone has good economic conditions to buy a whole new machine out of the store but has to choose to cut costs by buying old parts retail, and VGA is one of the options. the most reasonable for users to temporarily feel secure when buying old thanks to their high longevity.

But in the midst of the “coin card” craze in the present time, gamers who buy old VGA will easily encounter “buffalo card, industry card” being dropped to the market by people, with poor quality, quickly hot and damaged but still screaming prices in the sky, making “money lose money”. Understanding the willingness of gamers readers, in this article, GVN360 will introduce to everyone how to avoid being tricked into selling high-priced buffalo cards by “coin-gamer” and some useful advice for you for the first time. Build a machine or go to the old market to find a card. *

The first and easiest way to recognize: “Identity card” of the card.

For “general users”, there is no reason that they would discard the card’s paperwork because this is a pretty big investment, and everyone wants their card when something happens. Shop warranty both. Old cards with proof of sale, warranty, and full box are a huge plus, and you can rest assured about where they came from.

Most gamers will not have the need “I love science” to the point of removing all the components of the card. So we can check whether the sticker on the screw on the back of the card is punched or not. If so, first the company and the shop will deny the warranty for this VGA, secondly this is a sign of dismantling the card to change components or replace the heat sink glue because of plowing too much.

In conclusion, there are 3 ways that we can identify through the card’s paper as follows:

  • Check sales papers, invoices, warranty cards, containers.
  • Check the stamp on the screw on the back of the card.
  • If you don’t have the papers, check that the card’s serial number matches the product on its home page.

Next: Identify through the Card’s appearance

The VGA for mining is usually used non-stop for 24 hours, so they need a large industrial heatsink, blowing directly into the running card, which leads to moisture in the air and working. The card will oxidize very quickly, causing rust on the screws, the inside of the connection ports, the capacitor solder, …

As for the connection port shield, the material structure of this area will not be of high-quality metal on the inside, so it is possible that they will rust even if they are just working normally. However, if you find that the metal shield is too new compared to the screws, radiator fins, copper pipes inside, it has definitely been replaced, and obviously if just a normal user, no one will go. replace this shield both.

Because of continuous operation, if the heatsink is just a little bad, the capacitors will get hot, swollen and distorted very quickly, and the circuit board behind the card is also yellowed.

For the radiator fan, you can put your hands on the test rotation, and always running at full capacity to cool makes the fan not spin because the oil is dry, it can be loud when running, vibrating or rotating unevenly. If used for a long time, there will be broken blades, lost fans.

The port area shield is not screwed. Usually, the plowing card system will not be attached to the main but will be hung on a metal frame. So if you see that the hole in the card’s shield shows no signs of screwing, this is definitely a genuine “coin card”.

If this is a card sold by the company/distributor to a professional plow, the warranty stamp will usually be limited to 1 year, and if it is for the gamer, the warranty period will be more.

A certain part of the card suddenly became too new, too perfect compared to the general condition of the VGA, it was certainly replaced during use, by damage due to over-plowing, or some other reason. other.

So, the signs to identify through your appearance include:

  • Parts of the card are oxidized and rusted
  • Some parts are too new for the rest, especially the connector shield
  • Fan rotates weak, difficult to rotate, can emit loud, shaking sounds.
  • The capacitors are hot and deformed
  • The shield is not snails
  • Warranty stamp is limited to 1 year only

The last way: Recognize by software

– The mining cards are usually mod bios to increase productivity, you can use GPU-Z to see if the parameters, clock speed, … are the same as the original manufacturer’s specifications. If the clock speed is DOWN, it can be confirmed that the card has been modified for mining.

– Use 3D Furmark within 30 minutes, if your card is still at 85 degrees Celsius or less then it is normal condition. Also, the temperature is too high (more than 90 degrees C), maybe the VGA has dried out the thermal paste or the heatsink is running inefficiently, and the reason for this is usually because the card is overactive: mining. However, this approach is not recommended by GVN360, because this software works by getting the card to overclock, maxing its capacity, and this is very harmful to the card, regardless of whether your card is 100% new.

The ways to identify fake VGA through the appearance and software that I mentioned above only help you to assess the preliminary and most general but can not confirm with certainty. Because currently professional mining facilities often have modern equipment to optimize the “gold mining”. The buffalo groups will be plowed in cool air condition, meeting the standard temperature and humidity, the room has no dust, making them always in a near-perfect condition. At the same time, the owner of the facility also kept the box to easily push the VGA away when they ran out of stock but still could forcefully say “99% new, install the game twice and then disassemble full box.”

So to avoid buying “industry cards”, what should we keep in mind?

– Choose to buy old VGA with VRAM capacity below 4GB, as low as possible based on your usage needs. Cards with VRAM under 4GB will usually be less popular for mining, while AMD’s RX codes, with 8GB VRAM are definitely a “hot pick” for this “plow” industry.

– Choose VGA with single fan: with normal heat dissipation performance, these will avoid the eye of gamer.

– If possible, ask the seller to let you check and guarantee the return for a few days, then plug in and check the performance of the card, as checking the appearance is not enough with the refurbishment and Sophisticated refresh of some professional miners.

– A reputable exchange and trading place will help you get consultation and guidance from the community. You will know whether the person who sells the card to you is a trader, coin player, or gamer through their Facebook profile and the posts they have posted in the group. At the same time, if something goes wrong, you can still ask the help of a large community in the technology village to “reclaim the religion”, very wonderful, right?

Through the last article, I hope you are looking to buy old VGA will avoid “buffalo card, industry card”, and soon complete your desired PC system. Or if you are more economical and feel that finding the right old video card is too difficult and time-consuming, you can still refer to GearVN’s machines that are selling, with varied configurations and prices. suitable for all different usage needs of users. At the same time, when buying movements at GearVN, you will receive many incentives and other attractive gifts, along with the dedicated care and consultation of the sales staff, and Return warranty policy the store’s peace of mind too.
