In some new documents, first posted by Hans de Vries shows a diagram of a Titanite 2P2G system, packing not just one, but two of AMD's next-gen EPYC "Genoa" SP5 CPUs. Each of the chips supports 12 DDR5 modules, as well as having PCIe 5.0 support.

As for the AMD EPYC "Genoa" CPU and motherboard, it will support up to 384GB of DDR5-5200 RAM with RDIMMs. The CPUs will support up to 6TB of DDR5-4800 with LRDIMMs, but when 3DS RDIMMs (3DS taps through-silicon vias) is used we're looking at up to 12TB at DDR5-4000 speeds.
