Apparently AMD couldn’t make the signal integrity work out with socketed RAM. (source: LTT video with Framework CEO)
IMHO: Up until now, using soldered RAM was lazy and cheap bullshit. But I do think we are at the limit of what’s reasonable to do over socketed RAM. In high performance datacenter applications, socketed RAM is on it’s way out (see: MI300A, Grace-{Hopper,Blackwell},Xeon Max), with onboard memory gaining ground. I think we’ll see the same trend on consumer stuff as well. Requirements on memory bandwidth and latency are going up with recent trends like powerful integrated graphics and AI-slop, and socketed RAM simply won’t work.
It’s sad, but in a few generations I think only the lower end consumer CPUs will be possible to use with socketed RAM. I’m betting the high performance consumer CPUs will require not only soldered, but on-board RAM.
Sound like a downgrade to me I rather have capability of adding more ram than having a soldered limited one doesn’t matter if it’s high performance. Especially for consumer stuff.
I definitely wouldn’t mind soldered RAM if there’s still an expansion socket. Solder in at least a reasonable minimum (16G?) and not the cheap stuff but memory that can actually use the signal integrity advantage, I may want more RAM but it’s fine if it’s a bit slower. You can leave out the DIMM slot but then have at least one PCIe x16 expansion slot. A free one, one in addition to the GPU slot. PCIe latency isn’t stellar but on the upside, expansion boards would come with their own memory controllers, and push come to shove you can configure the faster RAM as cache / the expansion RAM as swap.
Heck, throw the memory into the CPU package. It’s not like there’s ever a situation where you don’t need RAM.
All your RAM needs to be the same speed unless you want to open up a rabbit hole. All attempts at that thus far have kinda flopped. You can make very good use of such systems, but I’ve only seen it succeed with software specifically tailored for that use case (say databases or simulations).
The way I see it, RAM in the future will be on package and non-expandable. CXL might get some traction, but naah.
“brain dead easy thing”… All you need is to just manage signal integrity of super fast speed ram to a super hungry state of the art soc that benefits from as fast of memory as it can get. Sounds easy af. /s
They said that it was possible, but they lost over half of the speed doing it, so it was not worth it. It would severely cripple performance of the SOC.
The only real complaint here is calling this a desktop, it’s somewhere in between a NUC and a real desktop. But I guess it technically sits on a desk top, while also being an itx motherboard.
Signal integrity is a real issue with dimm modules. It’s the same reason you don’t see modular VRAM on GPUs. If the ram needs to behave like VRAM, it needs to run at VRAM speeds.
Soldered on ram and GPU. Strange for Framework.
Not strange at all.
They’re a business that makes its money off of selling hype to morons.

Ye the soldered ram is for sure making me doubt framework now.
Apparently AMD wasn’t able to make socketed RAM work, timings aren’t viable. So Framework has the choice of doing it this way or not doing it at all.
In that case, not at all is the right choice until AMD can figure out that frankly brain dead easy thing.

Oh yeah I’m sure you could’ve done it no problem
