128GB DDR5 ECC RDIMM Server Module

This 128GB DDR5 5600 registered DIMM delivers high-capacity error-correcting memory for enterprise servers and workstations. The 4Rx4 organisation and 1.10V operation suit dense multi-socket platforms that demand data integrity. IT teams handling virtualisation, databases or large-scale compute workloads will find the module fits standard 288-pin DDR5 RDIMM slots.

Replacing Lower-Capacity or Non-ECC DIMMs

Upgrading from smaller registered modules or unbuffered memory adds the capacity headroom needed for memory-intensive applications while gaining hardware error correction. The jump is worth it when workloads exceed current RAM limits or when soft-error protection becomes a requirement for uptime. Systems already populated with DDR5 RDIMMs can mix this module where the platform allows.

Build Integration: Registered DDR5 Platforms

The module requires a motherboard with 288-pin DDR5 RDIMM slots and a chipset that supports registered ECC memory at 5600 MT/s. No heat spreader is fitted, so airflow across the PCB must be provided by the chassis. The single-rank-per-package 4Rx4 layout leaves additional DIMM slots free for further expansion within the platform's maximum capacity.

Questions about this item

What motherboard slot and voltage does this 288-pin 1.10V DDR5 RDIMM require?

It fits a standard 288-pin DDR5 RDIMM slot and operates at 1.10V; the motherboard must support registered ECC DDR5 at that voltage.

Which way does the 4Rx4 CL46 module seat, and what step is often missed?

Align the off-centre notch on the module with the slot key, press firmly until both retention clips click; the step often missed is verifying the clips fully lock on both sides.

How can I tell when the 128GB ECC RDIMM should be replaced in continuous use?

Replace it if the system logs corrected ECC errors that climb steadily, if memory diagnostics report uncorrectable faults, or if the server becomes unstable under load.
