NEMIX RAM 64GB DDR5 4800 CL40 2Rx4 ECC RDIMM RS720QA-E12-RS8U memory upgrade

SKU CH-WCFS-PP65S MPN RS720QA-E12-RS8U

A 64GB DDR5 4800 registered ECC module built for ASUS RS720QA-E12-RS8U servers

  • Capacity64GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 64 GB capacity expands server memory headroom
  • DDR5 4800 MT/s speed matches platform specification
  • ECC registered design protects data integrity under load
  • 10 V operation reduces power draw per module
  • 288-pin RDIMM form factor fits ASUS RS720QA-E12-RS8U slots

Capacity and form factor

This is a single 64GB DDR5 registered DIMM built for server motherboards that accept 288-pin RDIMM modules. It operates at 4800MT/s with a CAS latency of CL40 and runs at the standard 1.1V for DDR5. The module uses a 2Rx4 organisation and includes on-die ECC for error correction.

Suitable systems and limitations

It is designed for the ASUS RS720QA-E12-RS8U high-density 2U4N rack server and other platforms that require registered ECC DDR5 memory. Systems that only support unbuffered UDIMM memory or non-ECC modules cannot use this part. Builders needing lower capacities or consumer desktop memory should look elsewhere.

Deciding specification

The registered ECC RDIMM interface is the single attribute that determines compatibility; the module will only function in motherboards wired for registered DDR5 with ECC enabled.

Perguntas sobre este artigo

Does the 288-pin DDR5 RDIMM fit the ASUS RS720QA-E12-RS8U 2U4N rack server memory slots?

Yes, the module is a 288-pin DDR5 RDIMM built for the ASUS RS720QA-E12-RS8U high-density 2U4N rack server.

What is the correct seating procedure for this registered ECC module, and which step is most often missed?

Align the notch with the slot key, press firmly until both side latches click, and verify the system registers the full 64 GB at 4800 MT/s — many forget to check the reported speed after boot.

When should the 64 GB DDR5 4800 CL40 2Rx4 RDIMM be replaced in a production server?

Replace it if memory diagnostics report uncorrectable ECC errors, if the module fails stress testing under load, or when a capacity upgrade beyond 64 GB per slot is required.
