  • RDIMM design ensures stable registered operation

Hynix 128GB DDR5-5600 ECC RDIMM

This Hynix HMCT04AGERA module provides 128GB of DDR5-5600 registered ECC memory using 3DS stacking technology. It is built for enterprise servers and workstations that require maximum capacity per DIMM slot with full error correction.

Suited for high-density server builds.

The registered ECC design and 3DS architecture require a server-class memory controller and registered DIMM slots. Standard consumer motherboards cannot use this module, so buyers building a home PC or workstation without registered memory support should look elsewhere.

128GB single-module capacity

A single RDIMM delivers 128GB at DDR5-5600, allowing extreme memory density in multi-socket platforms. Verify that your platform supports 3DS registered ECC DIMMs before purchase.
