System-specific DDR5 server module

This 32 GB DDR5 4800 ECC RDIMM is built for the ASUS RS700A-E12-RS12U 1U dual-processor server. It operates at 1.1 V with a CL40 latency and a single 1Rx4 rank. The registered design adds signal integrity for multi-socket workloads.

Compatibility and capacity fit

The module suits administrators expanding memory in the named ASUS 1U platform where registered ECC is required. It will not suit builds that need unbuffered UDIMMs, non-ECC memory or a different form factor. Buyers who want more storage capacity or a consumer desktop upgrade should look at something else.

DDR5 4800 registered ECC specification

The decisive specification is DDR5 4800 (PC5-38400) registered ECC RDIMM at 1.1 V with CL40 timing. This combination determines whether the module matches the server's qualified vendor list. Verify the part number MR38400-314K1 against your system documentation before ordering.

Questions about this item

Does the ASUS RS700A-E12-RS12U server need a specific DDR5 RDIMM slot population order for this 32 GB 1Rx4 module?

The ASUS RS700A-E12-RS12U motherboard manual defines the required slot population order for 1Rx4 registered DDR5 DIMMs; follow that sequence when installing this module.

Can I add this 32 GB 1Rx4 DDR5 4800 ECC RDIMM to an ASUS RS700A-E12-RS12U that already has factory memory installed?

Yes, provided the existing modules are also DDR5 4800 ECC RDIMMs and the combined configuration follows the motherboard's qualified vendor list and slot rules.

How can I verify the module is running at DDR5 4800 with ECC active after installation in the RS700A-E12-RS12U?

Enter the system BIOS or use a hardware-information utility to confirm the memory reports 4800 MT/s, CL40 timings, 1.10 V operation and ECC enabled.
