  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 192 GB total capacity from six 32 GB modules
  • DDR5 4800 speed with CL40 latency for responsive server workloads
  • ECC registered RDIMM design protects data integrity in mission-critical systems
  • 1 V operating voltage reduces power draw across all modules
  • Validated for ASUS RS720-E11-RS12U 2U dual-socket server compatibility

Capacity and compatibility

This 192 GB kit delivers six 32 GB DDR5 4800 ECC RDIMM modules built for the ASUS RS720-E11-RS12U dual-socket server. Registered buffering and on-die error correction keep mission-critical workloads stable under sustained load. The 1.1 V operating voltage matches the platform specification exactly.

Target deployment and limits

The kit suits IT teams expanding memory in the named ASUS 2U server where registered ECC DDR5 is required. Sites needing unbuffered UDIMM, non-ECC modules, or a different pin count cannot use this product. Buyers without access to the server's qualified-vendor list should verify compatibility before ordering.

Decisive specification

Registered ECC DDR5 4800 with a CL40 latency and 1Rx4 organisation is the single parameter that determines fit; the motherboard memory controller expects this exact combination. A mismatch in rank, buffering type or speed grade will prevent the system from posting.

Questions about this item

Does the kit include all six 32 GB modules or must any sticks be purchased separately?

The package contains the full 192 GB kit as six 32 GB DDR5 4800 CL40 ECC RDIMM modules, so no additional sticks are required.

Should I choose the 1Rx4 4800 CL40 version or a different rank and latency for the RS720-E11-RS12U?

This kit is built specifically for the ASUS RS720-E11-RS12U with 1Rx4 organisation, 4800 MT/s speed and CL40 latency, matching the server's qualified memory list.

What does the 4800 MT/s rating mean once the modules are installed in the server?

The memory will run at 4800 MT/s (PC5-38400) with ECC and registered buffering, delivering the rated throughput and error correction for the dual-socket ASUS platform.
