Targeted Server Upgrade

This 16GB DDR5 ECC RDIMM is built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. Registered buffering and error-correcting code protect data integrity in mission-critical workloads. It suits IT professionals who need validated stability for server environments.

Straightforward Installation

The module slots into a standard 288-pin DDR5 RDIMM socket and operates at 1.1V. No heat spreader is fitted, so clearance is minimal. Builders must confirm the motherboard supports registered ECC memory; unbuffered or non-ECC boards will not accept this module.

Registered ECC Requirement

The single deciding specification is registered ECC RDIMM architecture with CL40 latency at 4800MT/s. Systems requiring unbuffered memory or non-ECC operation cannot use this part. Match the registered ECC requirement exactly before ordering.

Questions about this item

How can I confirm the DDR5 4800 ECC RDIMM is running at CL40 after installation?

Enter the BIOS or UEFI on the ASUS Pro WS WRX90E SAGE SE and verify the memory frequency shows 4800 MT/s with CAS latency 40 and ECC status enabled.

What ships with the MR38400-618K1 module and what must I source separately?

The box contains one 16 GB 288-pin DDR5 RDIMM; no heat spreader or additional cables are included, so ensure the workstation has free registered DIMM slots.

Which capacity and rank should I choose for the ASUS Pro WS WRX90E SAGE SE?

This kit is a single 16 GB 1Rx8 module; add identical modules to populate each channel evenly for maximum registered ECC bandwidth.
