Server Memory Kit

This 512GB kit contains four 128GB DDR5 4800 ECC registered DIMMs built for the ASUS RS720-E11-RS24U dual-socket server. The modules run at 1.1V with CL40 latency and use a 4Rx4 organisation. They are designed for mission-critical workloads that require error correction and registered buffering.

Suitable Applications

This memory suits administrators expanding the ASUS RS720-E11-RS24U to its supported capacity for virtualisation, database or high-performance computing tasks. It is not for desktop PCs, workstations or laptops that accept only unbuffered non-ECC DDR5. Builders needing lower capacities or different server platforms should verify their motherboard qualifications first.

Deciding Specification

The kit provides 512GB total capacity across four 288-pin DDR5 RDIMM modules operating at PC5-38400 speed. This capacity and registered ECC format are the primary factors that determine compatibility with the target ASUS 2U server.

Highlights

  • 512 GB total capacity from four 128 GB modules
  • DDR5 4800 speed with PC5-38400 bandwidth for server workloads
  • ECC registered design detects and corrects data errors
  • 1 V operation reduces power draw in dense configurations
  • Validated for ASUS RS720-E11-RS24U 2U dual-socket server

Questions about this item

Does the ASUS RS720-E11-RS24U server board require all 24 DDR5 slots to be populated for this 512GB kit to function?

The kit provides four 128GB modules; the RS720-E11-RS24U supports up to 24 DIMMs, so you can install this kit in the appropriate channels without filling every slot.

If I keep existing DDR5 4800 RDIMMs in the same server, will the new 4Rx4 modules run at the same CL40 timing?

The board will train all installed DDR5 4800 RDIMMs to a common speed and latency; matching CL40 on the new modules helps maintain uniform timing across channels.

After installation, how can I verify each 128GB module is recognised as 4Rx4 ECC registered memory?

Check the BIOS memory configuration or OS tools such as dmidecode; each DIMM should report 128GB, DDR5 4800, 4Rx4, ECC registered, and 1.10V operation.
