64 GB DDR5-5600 ECC Registered Module

This 64 GB DDR5-5600 CL46 module uses 2Rx4 registered ECC SDRAM on a 288-pin DIMM. It is built for servers and workstations that require error correction and registered signal processing for large memory configurations. The module operates at 1.10 V with Hynix A-Die components.

JEDEC DDR5-5600 Standard Limits

The SPD is programmed to JEDEC standard DDR5-5600 timing of 46-45-45 at 1.1 V. Registered modules reduce electrical load on the memory bus, allowing higher total capacity per channel. Speed and latency are fixed by the JEDEC profile; no XMP or overclock profiles are present on this part.

Installation and Common Issues

Insert the 288-pin DIMM into a compatible DDR5 RDIMM slot until the retention clips engage. The module has no heat spreader, so ensure adequate airflow in dense configurations. Common issues include mixing registered and unbuffered DIMMs or populating slots the motherboard manual reserves for specific ranks.

Questions about this item

Should I pick the 64GB DDR5-5600 CL46 module or a different capacity for my server?

This module provides 64GB in a single 288-pin DIMM. Choose it when your platform supports 2Rx4 registered ECC and you need maximum density per slot.

What does the DDR5-5600 rating deliver once the module is installed?

The module runs at 5600 MT/s with CL46-45-45 timings at 1.10V, giving a peak transfer rate of PC5-44800 while maintaining ECC integrity.

How does the DDR5 interface and registered design affect real-world limits?

DDR5 at 5600 MT/s is the JEDEC standard speed for this module; the registered buffer reduces electrical load on the memory bus, allowing stable operation at full rated frequency.
