gollark: Connect PCIe devices, mostly, which you can do now.
gollark: As far as I'm aware, the traces on the boards for the DIMMs have to be very precise lengths and stuff or the signals will get messed up.
gollark: That's totally impractical.
gollark: Sure?
gollark: Then buy bigger DIMMs and replace the ones you already have.
