Important Configuration Notes
- Only Intel Xeon x2xx Series (Cascade Lake-SP) processors can use memory modules built with 16Gb density DRAM. BIOS/firmware updates and/or specific board revisions may also be required.
- Faster memory will clock down to run at optimal speeds depending on processor model installed.
- Registered RDIMM and Load Reduced LRDIMM memory modules CANNOT be mixed within the same system.
