Who can tell me how to check the serial number of sapphire's video card by texting? Every time I send it, I say the format is wrong. . . How should I write it?

Here's the thing. When the graphics card inquires the authenticity, the user is required to send a serial number. In your case, if it is based on the format on the graphics card and the serial number you just scraped off, it can only indicate that there is something wrong with the graphics card. If it has been scraped off before, there are two situations. Either it has been queried before, and the system only recognizes success when querying for the first time. In the future, I will give feedback in the wrong format. Either there is something wrong with the graphics card.

However, this is not the only identification method. It can be directly tested with 360, and the parameters are basically accurate.
