  • 1 V low-voltage operation on 288-pin DDR5

Compatibility and Use Case

This 512GB kit targets administrators expanding memory in the ASUS RS720-E11-RS24U 2U dual-socket server. The eight registered DIMMs provide ECC protection for workloads that require data integrity. Builders using other platforms or desktop motherboards cannot install these modules. Systems needing unbuffered memory or non-ECC operation should select a different kit.

Deciding Specification

The registered ECC RDIMM design is the single attribute that determines fit. Only motherboards wired for registered DDR5 with on-die ECC support will POST with this kit. Standard consumer boards and workstations expecting unbuffered DIMMs will not function.
