Which makes it a very strange entry for a brand marketing itself as the DIY dream This was also my first thought when discovering this new model, but I think it was a pragmatic design decision. The questions you should ask yourself are: - which upgradable memory module format could be used with the same speed and bandwidth as the soldered in solution, - if this solution exists, how much wo…

CAMM perhaps? The modular memory is important, because they are selling them to two different markets: gamers that want a small powerful desktop, and people running LLMs at home. The modularity of the RAM allows you to convert the former into the latter at a later date, so it seems pretty critical to me.

For this reason alone, I am going to buy a used epyc server instead of one of these desktop things. I will be able to equip it with a greater amount of RAM as I see fit and run a greater range of models (albeit at lower speed). The ability to run larger models slowly at a later date is more important than the ability for me to run smaller models faster now. So I am an example of a consumer who does not like framework's tradeoff.

You would think that they would at least offer some type of service where they take it into the factory and refit it with new ram chips. Perhaps they could just buy used low-ram boards at a later date and use them to make refurbished high-ram boards.

Another solution is to make it so that it supports both soldered and unsoldered ram (but at a lower frequency). Gaming is frequency-limited but does not require much ram, but a lot of workloads like AI are bandwidth limited. Hell, if you're going to have some high-frequency RAM irreplacibly soldered to the motherboard, it might as well be a chiplet!

You can also use an adapter to repurpose an M.2 slot as PCIe x16, but the bandwidth is the same x4

For LLM inference, I don't think the PCIe bandwidth matters much and a GPU could improve greatly the prompt processing speed.

The RAM is soldered on all Halo Strix platforms because physics is getting in the way. With pluggable DIMMs the memory bandwidth would be halved, at best.

Why not make a platform with a greater number of channels

He is still right. It is a desktop PC that is less repairable than all other desktop PCs, from a brand that is known to champion repairability. They had a reason for it, but could've chosen to not create more throwaway things.

The 128GB version wouldn't be throwaway, since that's the maximum the platform as a whole supports anyway- more memory than that would require a new mainboard and CPU at the same time.

the platform should support more memory

Why is that? Why would soldering the connections vs plugging them in affect how much data per second they transfer?

Sockets have resistance and crosstalk, which affects signal integrity.

Wait, your telling me, I should have been desoldering the sockets off my motherboard, and directly soldering my RAM to the leads this entire time?
