If the CPU can be socketed, there is no reason RAM can't be.

The boards using LPDDR don't have socketed CPUs. Also, every connector is a huge hit to your signal integrity, so one versus two might indeed be a big deal.

And yeah, it can be, but that's how you end up with the far slower regular DDR. Fast, repairable, cheap: pick (at most) two.

		No, even in multiple RAM channel Server, the CPU is still socketed. That means all the data is going through a socket before reaching the CPU. I agree there is draw back when using socket(mostly size), but performance is not the big issue. MRDIMM RAM can reach even higher Transfer rate than LPDDR5, yet still socktable.

Effectively there are no socketed CPUs for laptops, though, for way more than a decade already. Saying that as I'd fully support modular components, as in desktops.

		Tsinghua Tongfang (and I think Clevo) offers customizable laptops. Resellers might use own branding. CPU and RAM are socketed. Clevo had socketed graphics cards too
