System-Specific DDR5 Kit

This 1.5 TB DDR5 4800 ECC RDIMM kit contains twelve 128 GB modules built for the ASUS RS520A-E12-RS24U 2U server. Registered buffering and on-die ECC protect data integrity in mission-critical workloads. The kit arrives as a matched set validated for that platform.

Compatibility & Limits

Suits administrators upgrading the named ASUS single-socket 2U server to its maximum supported capacity. Not for desktop boards, workstations lacking RDIMM support, or systems that require unbuffered UDIMMs or a different DDR generation. Builders needing lower capacities or non-ECC memory should look elsewhere.

Decisive Spec

Registered 4Rx4 organisation at 1.10 V with CL40 latency determines whether the server’s memory controller will accept the kit. The 288-pin DDR5 form factor and PC5-38400 speed rating must match the platform’s qualified-vendor list exactly.

Highlights

  • 5 TB total capacity across twelve 128 GB modules
  • DDR5 4800 MT/s speed rated at PC5-38400
  • ECC registered design protects data integrity in servers
