MSI has teased a concept Z790 motherboard that features CAMM2 memory. The board is called the Project Zero Plus. We reviewed a system with the B650 Project Zero a little while back. It's main feature us that all the major connectors are relocated to the rear of the motherboard, including the power connectors, system headers and SATA ports, but this new concept with CAMM2 memory something altogether different.
MSI and @kingstontech are previewing the next revolution in memory design, the DDR5 CAMM2.
