I’m happy to announce we are now confident enough that we can fit two SO-DIMM slots into the Librem 14 that we have updated the specs. You can read more in our Librem 14 Launch FAQ we just published:
Q: How many RAM slots are there?
A: Two. There is a small chance during final mechanical design testing that we have to drop back to one, but we are confident from our early MD testing it will work so are offering two RAM slots, up to 64GB of RAM.
