The obvious solution would be to use DDR5 SODIMM which has 262pins, but that still feels like using the wrong tool for the job -> Is there a better connecting solution for this usecase?

## Possible solutions
### Use of Edge Connectors
Edge connectors are set of contact points on the edge of the PCB designed to slot into a connector, for example it's often used on PCIe x16 graphics cards:
![image](https://git.dotya.ml/attachments/54bd7c9b-b9d6-49ac-9965-5e1fb7d6ee55)
Which has a bevelled edge (minor added cost to fabrication) to fit in the connector

One solution could be to standardize these connectors and invent a symbol that can be put over them signaling that they follow this standard.
Furthermore in practical example this can be adjusted to making Single Board Computers ("SBCs") more functional:
Lets imagine that we have [OLIMEX OlinuXino-A64](https://www.olimex.com/Products/OLinuXino/A64/A64-OLinuXino/open-source-hardware) board as an example:

which could have an edge connector some-what painlessly added to it

(note that contacts are on both sides of the PCB)
This would efectivelly enable OSHW manufacturers to adjust their SBCs so that they can be slotted in this solution.
