Server Memory Upgrade

This 128GB DDR4 module is built as a compatible replacement for the Samsung M393AAK40B41-CTC. It targets administrators who need to expand capacity in servers or workstations that require registered ECC memory. The single stick delivers 128GB at DDR4 2400 speed.

Registered ECC Design

The module uses a 288-pin DIMM form factor with a 2S4Rx4 (8Rx4) organisation based on 3DS/TSV stacking. Registered buffering and ECC error correction help maintain data integrity under sustained workloads. Operation at 1.20V matches the standard DDR4 voltage level.

DDR4 2400 Platform Limit

The PC4-19200 rating sets the maximum transfer rate for this module. Systems that only support lower DDR4 speeds will clock the memory down to the highest compatible frequency. Buyers needing higher bandwidth or different rank configurations must verify platform specifications before ordering.

Questions about this item

What does the DDR4 2400 (PC4-19200) rating mean for real-world throughput?

DDR4 2400 (PC4-19200) indicates a 2400 MT/s data rate with CL17 latency at 1.20V, the standard voltage for DDR4 server modules.

Will this 288-pin RDIMM fit my server's DIMM slots?

The module uses the standard 288-pin DDR4 DIMM form factor; verify your platform supports 128 GB 2S4Rx4 (8Rx4) 3DS/TSV registered ECC RDIMMs before installing.

How do I install this registered ECC module correctly?

Power down, ground yourself, align the notch with the slot key, press firmly until both retention clips click, then confirm the full 128 GB is recognised in BIOS/UEFI.
