I understand the memory constraints but it does feel weird for framework, is all I have to say. But that's also the general trajectory of computing from what it seems. I really want lpcamm to catch on!
Apparently Framework did try to get AMD to use LPCAMM, but it just didn't work from a signal integrity standpoint at the kind of speeds they need to run the memory at.
Sounds like it doesn't bode well for the future of DIMMs at all, TBH.
You have a DIMM view of the future.
My AM5 system doesn't post with 128GB of 5600 DDR5 at higher than 4400 at JEDEC timings and voltage. 2 DIMMs are fine. 4 DIMMs... rip. So I'd say the present of DIMMs is already a bit shaky. DIMMs are great for lots of cheap RAM. I paid a lot less than what I'd have to pay for the equivalent size of RAM in a Framework desktop.
Eventually most system RAM will have to be packaged anyway. Physics dictates that one pays a penalty going over pins and mobo traces, and it gets more severe with every advancement.
It's possible that external RAM will eventually evolve into a "2nd tier" of system memory, for background processes, spillover, inactive programs/data, things like that.
That would be fine. But as long as it can use it as RAM and not just a staging ground.
Keep in mind that it would be pretty slow, as it doesn’t make sense to burn power and die area on a wide secondary bus.
