LPCAMM2 sockets were supposed to provide all the benefits of soldering while still being a socket. Anyone know the state of adoption?

The new Framework 13 Pro laptop ships with LPCAMM2.

yeah but there is very little interest in that model compared to ai max line

But no ECC support.

the fact no component supplier, not even alibaba sells LPCAMM2 sockets tells you everything you need to know. The only prices I can find are in $30 range per socket

Connectors are expensive, high-speed ones particularly. $30 is fine, though it makes a giant difference at what quantity that is. Did you look at a single one or 1k?

No, $30 is not fine :) This isnt a magic connector, its not more complicated than $7 AM5, $6 LGA1851 or $5 LGA1700 all in single quantities, and those prices go way down bulk. Those are all banged out by machines running 24/7 lights out.

No supplier carries those connectors, there are no 1K prices I could find anywhere.

Honestly, reasonable.

I've been eyeing LPCAMM2 interposers for non-RAM uses - as an off the shelf connector for stacked PCB designs. The conclusion was that it wasn't produced or used at sufficient scale for it to work.

All of the new NVIDIA data center GPUs use SOCAMM2, quite similar to LPCAMM2.

You can't buy a single LPCAMM2 RAM module on Amazon. eBay has some.

Lenovo uses it on their latest thinkpad t14.
