System-specific DDR5 ECC RDIMM

This is a single 128GB DDR5 4800 CL40 4Rx4 288-pin 1.1V ECC Registered RDIMM validated for the Gigabyte R283-P93 platform. It is built for workstations, servers and NAS systems that require registered ECC memory. The module meets JEDEC and RoHS standards. It will not work in standard desktop computers.

Installation and common issues

The DIMM installs like any 288-pin DDR5 module, but the platform must support registered ECC memory and the exact 4Rx4 organisation. Mixing this module with unbuffered or load-reduced ECC DIMMs will prevent the system from booting. Verify that the Gigabyte R283-P93 firmware recognises 128GB single-rank capacity before purchase.

Suitable buyers and mismatched needs

This module suits administrators upgrading or repairing a Gigabyte R283-P93 server who need maximum single-slot capacity with error correction. Buyers who want memory for a consumer desktop, laptop or non-ECC workstation should look elsewhere. Systems that cannot accept registered 4Rx4 DDR5 or that require unbuffered or load-reduced ECC are incompatible.
