If they made the memory upgradable it would defeat the purpose of the machine, since memory modules can’t hit the same speed as soldered memory.

If you’re buying this you’re probably maxing out the memory to start with. 128GB is borderline barely adequate for local LLMs.

You can get DIMMs that do 8000 right now, and LPCAMM2 should become capable of even higher speeds even though it's "only" 7500 at the moment.

Framework says in their blog post that they talked to AMD about using LPCAMM2 and the engineers "finally concluded that it was in fact not possible without massively downclocking the memory". And okay, I believe them, but I'm pointing my blame a lot closer to the CPU than the memory modules.

The other difference with AMD's AI Max is that it's using a 256-bit bus compared to LPCAMM2's 128-bit bus.

Half your data lines run to each module, and you can put them both tight against the socket, so no routing issues there. If there's a control line that would need to be shared across both modules, and it can't be shared in a fast way, or there's some weird pin arrangement that causes problems... oh look I'm back to blaming the CPU.

If they made the computer unupgradable it would defeat the purpose of their company.

LPCAMM2 can, its a shame Framework couldn't make it happen.
