Although the P104 is a mining card, it has 8G memory and a core equivalent to 1060 after the magic modification , and the price of Xianyu is only about 150 yuan . It may be quite cost-effective to run tasks such as deep learning. That is to say, you can use some cheap second-hand hardware to build your own cheap computing power platform. However, sometimes P104 will not recognize the card at all.
I bought a magic-modified 8G P104 graphics card and wanted to use it to run novelai, but no matter how I tried it in the Ubuntu environment, the driver could not be installed. I thought it was a problem with the system environment, so I switched to Win10 and tested it. At this time, I found that the device information of the graphics card was not recognized at all .
After tossing, I considered that the motherboard and the graphics card may not be compatible . The motherboard I used was ASUS’s P8Z68-V. The PCIE slot used supports the PCIE x16 standard, and the output supported by the P104 graphics card is the PCIE x4 standard.

Graphics card PCIE standard
So the reason may be that the PCIE slot of the motherboard is x16, and sometimes it cannot automatically adapt to the x4 protocol. At this time, you can use tape to shield the contacts behind the 20th pin (including 20) on the graphics card interface .

Wrap it with insulating tape like this and put it on the machine.
You can already see the information of NVIDA
After that, the official driver can be used normally
