32GB DDR5 4800 ECC RDIMM server module

This 32GB DDR5 4800 ECC RDIMM module is built for the ASUS RS720-E11-RS12U 2U dual-socket server. It runs at PC5-38400 speed with CL40 latency and 1.10V voltage. The registered 1Rx4 design uses major OEM chips for stability in enterprise workloads.

Compatibility and use-case fit

Suits administrators expanding memory in the named ASUS 2U server where registered ECC DDR5 is required. Not for desktop PCs, laptops or workstations that accept only unbuffered non-ECC modules. Builders needing higher capacities per slot or different form factors should verify the platform's qualified-vendor list.

PC5-38400 registered ECC specification

The decisive spec is the DDR5 4800 PC5-38400 registered ECC RDIMM standard with 288-pin layout. Only systems that explicitly support this exact registered ECC DDR5 configuration will accept the module.

Questions about this item

How can I verify the 32GB DDR5 4800 CL40 module is running at 4800 MT/s with ECC active after installation?

Enter the server BIOS or use a tool like dmidecode to confirm the reported speed is 4800 MT/s, the CAS latency shows CL40, and ECC status reads enabled for the 288-pin RDIMM.

What ships in the package and are any extra parts such as heatsinks or cables required?

The box contains one 32GB 1Rx4 DDR5 4800 1.10V CL40 288-pin ECC RDIMM module; no heat spreader is fitted and no additional components are needed for installation.

Should I choose the 32GB 1Rx4 CL40 version or a different capacity or rank for the RS720-E11-RS12U?

This 32GB 1Rx4 CL40 DDR5 4800 1.10V RDIMM is the configuration validated for the ASUS RS720-E11-RS12U; select it when matching the server's qualified memory list.
