128GB DDR5-5600 ECC RDIMM Server Module

This 128GB DDR5-5600 registered DIMM targets servers and workstations that require error-correcting memory for data integrity. It operates at the standard 1.1V DDR5 voltage with a CAS latency of 40 and uses a 4Rx4 3DS/TSV organisation built with major-brand DRAM ICs.

Installation notes and common issues

The module fits a standard 288-pin DDR5 RDIMM slot and installs like any registered DIMM; follow the system manual for correct channel population and seating order. Because it is a 4Rx4 load, some platforms may limit the number of modules per channel or require a specific BIOS revision to initialise at 5600 MT/s.

Suited for capacity-focused servers.

This module suits administrators upgrading Hynix HMCT04AGERA, HMCT04AGERA199N or HMCT04AGERA200N parts in compatible enterprise chassis. It will not work in desktop or consumer boards that accept only unbuffered non-ECC UDIMMs, and it cannot be mixed with single- or dual-rank modules in the same channel on most server platforms.
