64GB DDR5 ECC Registered RDIMM

This single 64GB DDR5 5600 module is built for workstation and server platforms that require registered ECC memory. It targets administrators upgrading Gigabyte E163-S30, E263-S30, E283-S90, G293-S40 or G293-S41 systems with JEDEC-compliant parts.

288-pin registered form factor

The module uses a 288-pin RDIMM connector with a 2Rx4 organisation and operates at 1.1V without a heat spreader. Registered buffering and ECC support mean it cannot be mixed with unbuffered or load-reduced DIMMs, so the memory controller must expect registered modules.

DDR5 5600 CL46 speed grade

The decisive specification is the DDR5 5600 (PC5-44800) CL46 rating, which determines whether the module matches the platform's qualified memory list. Buyers needing unbuffered ECC or consumer SO-DIMMs will not be able to use this part.
