We have previously reported that Chinese netizens bought cheap RTX 3080 mining cards.It turns out that 2GB of display memory is broken.This leaves only 8GB, and even the interface bandwidth is reduced to 256 bits. In fact, this is not the only one who paid a heavy price this time, there is another netizen who suffered even worse. Just a few days after buying it, the display became abnormal, which meant that it was completely unusable. The important thing is that he also spent a lot of money to buy this graphics card.

A tragic case of buying an RTX 3080 mining card for cheap, it showed abnormality within a few days of purchase.

Recently, an ee2d Bilibili channel owner shared his advice on buying an RTX 3080 mining card. He bought this card about a week ago. He also shared in the news that “4000 yuan ROG 3080 mining has gone down the mountain, and the 40 series is no longer available. I think this price is OK.” When I bought it, I also tested whether it could be used normally. At that time, there was indeed no problem at all, the display was not faulty, and I even turned on GPU-Z Check whether he has been castrated or tampered with. For details, you can watch his Bilibili video:

The RTX 3080 can now be bought in China for about 5,000 RMB, which is about NT$22,000. He bought this mining card for 4,000 RMB, saving 1,000 RMB, which is about NT$4,400. To be honest, he did not save a lot, but the ee2d was very happy after buying it. He even adapted Jay Chou’s Big Ben into it.Great injustice”, the lyrics read:

“Take care of yourself and wait for your 40 series
Stop beeping here. Listen carefully.
You are so awesome, it doesn’t matter whether it makes sense or not.
You are so smart, you spray me out of justice
Because I’m really not sober
But my card is fine and I can play games stably yeah
I’m really proud~
wow oh wow oh baby
It doesn’t matter if you criticize me, I’m very satisfied with the card.”

As a result, tragedy struck just 2 days after this adapted song was released. ee2d uploaded another song “The 3080 mining card I just bought a week ago has a corrupted screen.” video, you can see that although the screen can be displayed, it is obviously abnormal. Not only are the color blocks incorrect, but they also keep flickering, making it basically unusable:

The mining card cannot be sent for repair and warranty. The representative said that he can only find a third-party repair center in the market to deal with it. This will definitely charge a fee, and the actual repair may be more expensive than the NT$4,400 he saved. He also advised everyone in the video, “Brothers, please don’t buy a mining card. Don’t go down the mountain just for cheap like me. My graphics card is broken now. How can I fix the blurry screen? It broke just a few days after I bought it.”:

Compared with brand-new graphics cards, although mining cards are cheap, some of them are really discounted to 50 or 40% off, which is very tempting. But even if you really save thousands or even tens of thousands, you may be unlucky. Like ee2d, it will break within a few days after buying it, and the money you spend will turn into a waste. It is not worth it. Moreover, the mining cards that are discounted to 50 to 60% are usually in poor condition.

I sincerely recommend that you don’t buy a mining card for cheap at this time, unless you really trust the other party and he is willing to provide a few months of warranty. Otherwise, it is like gambling, and the odds are not very good. It is better to wait for a new graphics card to be on sale.
