## Key points

- Current-gen Ryzen CPUs lack IMCs compatible with CUDIMM DDR5, even if motherboards are updated.
- CUDIMM DDR5 modules on existing CPUs will run in 'Bypass' mode, limited to ~6000 MT/s.
- Next-gen CUDIMM support will require Zen 6 Ryzen CPUs, not just a BIOS or AGESA update.
- ASUS is adding EXPO 1.2 BIOS support to both new and older 600-series AM5 motherboards.

**Companies:** AMD, ASUS, MSI
