What is the name of the adapter for memory slots?

Question

Iron

I don’t know what to enter in Google search, I
saw somewhere on Ali an adapter that can be plugged into a memory slot and plug several memory sticks into the adapter, that is,
if there are not enough slots in the motherboard for the required number of strips

Thank you

Answer 1

Most likely on ALI you stumbled upon the server Backplane. This is not a memory expander, but simply the removal of slots to another plane due to a physical lack of space - an integral part of the motherboard.
Or, in the days of DDR1, there was a progenitor of the SSD in the form of a physical 4-slat RAM disk, but it was an SSD and not RAM

Answer 2

All that can really be done with a dimm connector, if fantasy allows:
1) Add a PCIe connector or a couple of SATA for SSD or other drives.
2) Put laptop memory on a desktop motherboard.
Add one more line for a new RAM bar - in fact, the motherboard is the same adapter between the RAM and the processor, in the truest sense of the word. She stupidly forwards the conductors from the processor contacts to the contacts of the RAM strips. If you want more memory slots - put another adapter - the motherboard, if, of course, the characteristics of the processor allow (its memory controller).

Answer 3

It's impossible.
