Thanks to
@Steve for trying this out and sending me these images!
This new upgrade (not yet available) allows 4MB to be fitted to a older STM type machine.

Thats why I asked, I don't think there is clearance for sockets as well.

There looks to be at least one socket there.

They're soldered on to precision headers on the motherboard. You would only want to socket it if you're planning on removing the ram board for different reasons I'm not sure?
