128GB DDR4 2400 ECC Registered Server Memory

This 128GB DDR4 2400 (PC4 19200) module provides high-capacity ECC registered memory for enterprise servers. The 4Rx4 rank organisation suits dense multi-socket platforms that require error correction and signal buffering. It targets system integrators and IT departments expanding memory in qualified server chassis.

Installation notes and common issues

The 288-pin DDR4 form factor fits standard registered DIMM slots; alignment keys prevent backward insertion. Installations fail when mixed with unbuffered or non-ECC modules, or when the platform does not support 4Rx4 registered populations. Firmware revisions and memory-channel limits should be verified against the server vendor's qualified-vendor list before deployment.

DDR4 2400 bandwidth and capacity limits

At DDR4 2400 the peak transfer rate is PC4 19200, which caps throughput for memory-bound workloads compared to faster DDR4 speeds. The 128GB density per module reduces the number of DIMMs needed for large footprints, but total system capacity remains bound by the processor's supported memory channels and maximum registered-rank count per channel.

Questions about this item

How can I confirm the 128GB DDR4 2400 ECC Registered kit is running correctly after installation?

Enter the server BIOS or UEFI and verify the total capacity shows 128GB, the speed reads DDR4 2400 (PC4 19200), and ECC Registered mode is reported as active for the 4Rx4 modules.

What ships with the BD128G2400MQR96 and what must I source separately?

The package contains the 128GB 288-Pin DDR4 SDRAM modules only; no additional brackets, cables, or cooling hardware are included, so ensure the server has compatible DIMM slots and adequate airflow.

Which capacity and rank configuration should I choose for a server that supports 4Rx4 Registered ECC memory?

This model provides a single 128GB kit built as 4Rx4 Registered ECC DDR4 2400; select it when your platform requires that exact density and rank layout.
