So I was planning to modify my laptop to connect a GPU. And my laptop originally doesn’t have a GPU, not do it support thunderbolt. So I was planning if it’s possible to connect a GPU through DDR4 RAM slots. But since I can’t find any product on market supports that, I think I’ll have to wire it myself.
So I would like to ask is it possible to use a GPU connected on a RAM slot? If yes, how do I map it (cause I can’t find RAM slot‘s pin diagram on internet).
You cannot do this.
A RAM slot is connected to a memory controller. A GPU is connected via a PCIe bus. Those two things are not compatible and are not able to be interconnected.
A GPU may contain memory chips, but it is not "simply" a memory device. A GPU is a specialised computer which requires a host machine to provide instructions and data in order for it to do work.
The slots might look like they have a similar number of pins, but that does not mean those pins perform the same function or work in even vaguely the same way.
The only way to connect a GPU into your laptop is if it has a mini PCIe slot or Thunderbolt/USB-C, which effectively uses PCIe lanes over USB to achieve the same.
No, it's not possible. RAM slots can only house RAM sticks.
