TIL LPCAMM2 exists. What an awesome solution to allow memory replacements while meeting all of the other requirements for laptops.

Well to be fair they only kind of quasi-exist for consumers right now. As far as I can tell Crucial was providing the only consumer accessible lpcamm2 modules on the market right now.

Crucial is certainly the only option that comes up looking on amazon or newegg right now. Lenovo has some OEM modules but they are obviously marketed as replacement parts to just their laptops, not sure how the warranty and support for them would be outside a lenovo product.

But the Crucial brand was unceremoniously sacrificed by Micron to the AI gods at the beginning of this year. So will these lpcamm2 modules even be available once current stock runs out? The 64gb module is already sitting at $1000 on newegg.

Samsung is making lpcamm2 modules but no telling when those will actually hit the market and be accessible.

It doesn't meet all of them. AMD considered it for Strix Halo but said it didn't meet their latency requirements.
