As Double Eleven is approaching, many friends want to buy graphics cards again or DIY a host on their own. However, there are so many mine cards and on the market, especially a freighter has already docked, and tens of thousands of mine cards are immediately flowing into the market, which is also quite unfriendly for many friends who want to buy second-hand graphics cards. How to determine whether a graphics card is a mining card? Which models of graphics cards are the hardest hit areas for mining cards? Today I will explain the characteristics of mining cards in detail to avoid everyone from stepping on the mine.
1. How to determine whether the graphics card is a mining card?
First of all, there is no 100% reliable technical means to detect whether the graphics card is a mine card, but we can roughly judge whether the card is a mine card through various methods.
is the simplest and most rude method. By default, all second-hand graphics cards of 30 series in N cards are mine cards. Because the 30 Series graphics cards were used by a large number of miners to mine in the previous mine tide, ordinary people could not buy them. Now that the mining disaster is coming, the mining profit of 30 Series graphics cards has decreased, and these parts of the mining cards have begun to flow out. Moreover, the 30 Series graphics card itself has been launched not long ago, and it is impossible for ordinary computer players to eliminate the computer immediately. In addition to the low cost-effective RTX3050, if other 30 Series graphics cards are already in the second-hand market and are cheaper, then they are highly likely to be mine cards. RTX3060TI is the first choice for 30 series mining cards, so friends must pay attention.
1, query SN code , there will be SN codes on the graphics card packaging and back panel. The SN code needs to be integrated into one, that is, SN on the card, warranty card SN, and the packaging box SN must be consistent. Anything that does not have can be regarded as a mine card, because most mine owners are too lazy to keep these packaging and warranty cards. Also get retail tickets as much as possible. Graphics cards that have been torn off, smeared, destroyed product models, identification codes, SN code stickers or fan LOGOs can basically be judged as mine cards. These are low-level concealment behaviors. If they have not been used for 5 or 6 years, these tags cannot be damaged at all, so they are judged as mine cards will never leave. If the three codes are consistent, you also need to call the after-sales phone number of the corresponding brand to check the appearance date of this card. If it is normal within three months.
2, the yellow butt on the back of the graphics card (the GPU power supply module is yellowed and aged due to long-term high temperature), and the yellowing and aging of the video memory is basically considered a mine card. The normal use of the 30 series is far less yellow butt. In addition, you can see if the silicone heat dissipation pad between the heat dissipation module and the graphics card will leak oil, because this silicone heat dissipation pad will produce oil stains at long-term high temperatures. If there is such oil stain on the graphics card, 90% of it will be mine cards.
3, after purchasing, observe the default overclocking settings: GPU graphics cards with low clock frequency and high memory frequency can all be regarded as mining cards, and these are used to mine ETH. The graphics cards that are packaged and sold in batches of the same model are considered to be eliminated in studios and Internet cafes. The bosses are all using the 20 series to wait for the 30 series to be hungry, so how can they be released for you! Various graphics cards for self-used on Salt Fish, but those who sell various models of graphics cards and in their personal profile are considered as mining cards. Which ordinary person can grab so many graphics cards to use them and release them? Who are you lying to?
4, see if the seal of the electrostatic bag has been removed. This is disposable and cannot be restored if it has been removed.
5, observe the appearance of the graphics card, the cooling module, back panel, and bezel are free of dust and finger prints. If so, congratulations on winning the prize.
6, look at the fragile stickers. All brands of graphics cards will have fragile stickers. If fragile stickers are not available, it is proved that this graphics card has been removed.
7, look at the dust and dissipate heat to deceive the gap. Both the back of the fan need to be wiped with paper or cotton swabs, because the dust in this place is the most difficult to clean, and if there is dust, it is proven to have been used.
is used to distinguish whether there is a mine card. To do these points, you can basically avoid mine card, but you still cannot avoid mine card 100%. The more reliable method is not to buy second-hand cards, buy new cards on large platforms, and buy new cards with lock computing power launched by various manufacturers to deal with the mining trend, so that everything is foolproof.Most manufacturers will mark the lock computing power on new cards: the lock computing power suffix of Colorful will have "L", the lock computing power card suffix of Yingchi will have "FG", the lock computing power card suffix of Yingzhong will have "LHR", the suffix of suffix of suffix of suffix will have "G" or "GE", the suffix of Asus will have "V2", the 3060 listed on MSI , Mingxuan , and Gengsheng will have not been clearly marked, and there should be a logo similar to "LHR" at the end.
can measure the latest locking core model through GPU-Z 2.40.0 version. The 30-series card lock computing power core number:
3060: GA106-302
3060ti: GA104-202
3070: GA104-302
3070ti: GA104-400
3080: GA102-202
3080: GA102-202
3080ti: GA102-225
Which models of graphics cards are the hardest hit areas of mining cards?
2. Since there are many types of virtual currency , even lock computing power graphics cards can be avoided with dual mining software, let alone the full crack computing power mining software is available now.
new card first:
RTX3060ti, RTX3070, RTX3080,
These three cards have been miners' lovely buns since last year. Among these three graphics cards, especially RTX3060ti, mining is very cost-effective, and these three cards in the new cards have relatively great damage.
new card second gear:
RTX3090, RTX3060 (after cracking computing power), RX 6800XT, 6900XT and
are selected when they are intensifying their efforts to mine later. Compared with the first gear, the second gear is generally lower in the degree of victimization, and it is difficult to dig longer than the first gear.
Old Card First Level:
RX5700, RX 5700XT, RX 5600XT, RX5500XT, RTX2060Super, RTX2080Ti,
This is the hardest hit area of old cards. These cards have considerable cost-effectiveness and relatively large losses.
Old Card Second Level:
RTX2070 (Super), RTX2080 (Super), GTX1660Super, RTX2060,
These cards were collected in large quantities in the first phase, and they are also substitutes in the later stage.
retirement card first: (ETH can be mined for more than 4GB of video memory)
AMD: Radeon7 /RX590/RX580/RX480/ RX570/RX470/Vega56/ Vega64
NVIDIA: GTX1060 6GB/ GTX1080/ GTX1080Ti
There are many of them that can be mines in the mine, which means that during the 17/18 period, I was training in the mine farm. This wave of mine tide has been in training again. These cards are the hardest hit areas among the hardest hit areas
retirement card second level:
GTX1070, GTX1070Ti
This series of relatively first level damage is less, and it is also added later.
is based on the historical selling price and ETH computing power of each card. Although the video memory required to be greater than 4GB of digging ETH, many small currencies are not used, and many small currencies are also mined, so such as gtx1060 3G/RX 580 4G, it is also a severely affected area.
or above is which models of graphics cards are the hardest hit areas of mining cards. Detailed content of the methods to determine whether a graphics card is a mining card. If you are interested, please like, collect and follow me. I will update the basic knowledge of graphics cards and DIY hosts from time to time to avoid everyone's missed. You can also quickly master the DIY host methods and techniques when you are on the novice.
