"[AMD] ran simulations, they ran studies, and they just determined it’s not possible with Strix Halo to do LPCAMM. The signal integrity doesn’t work out because of how that memory’s fanning out over the 256-bit bus.”
"The guide confirms that the new Ryzen AI Max “Strix Halo” processors come in hardwired to LPCAMM2 memory configurations of 32 GB, 64 GB, and 128 GB, "
Lpcamm2 does 256 Gbs and are upgradable. There are already motherboards that support it.

From your quote:
“hardwired”
Lpcamm2 is by defniition not hardwired. This sentence reads, “Strix comes in hardwired to non hardwired memory configurations.”
Hmm. You are correct. I concede my point regarding upgradeable memory being an impossiblity for STRIX Halo.
