  • ECC registered design detects and corrects memory errors automatically
  • 1 V operation reduces power draw per module

768GB DDR5 5600 ECC RDIMM Kit

This 768GB kit contains twelve 64GB DDR5 5600 registered DIMMs with ECC and a CL46 latency. It is built for the Dell PowerEdge XE9685L rack server and similar platforms that require registered error-correcting memory. The modules operate at 1.1V using 4Rx4 organisation.

Registered ECC and 4Rx4 Organisation

Registered buffering and on-die ECC protect data integrity in multi-socket server workloads. The 4Rx4 rank structure lets each 64GB module present four logical ranks to the memory controller, increasing density per slot without changing the 288-pin form factor. No heat spreaders are included, so airflow in the chassis must handle thermal management.

DDR5 5600 Speed and Platform Limits

The PC5-44800 rating sets a 5600 MT/s data rate that the memory controller and BIOS must support. Registered DIMMs cannot be used in desktop or consumer boards that expect unbuffered modules. Mixed-rank or mixed-speed populations may reduce the effective speed below 5600 MT/s depending on the server firmware configuration.

Questions about this item

Will the twelve 64 GB DDR5 modules need any periodic maintenance or replacement?

No routine maintenance is required; the registered ECC DDR5 RDIMMs are solid-state with no moving parts and are designed to run for the life of the Dell PowerEdge XE9685L server.

What limit appears first when the 768 GB kit runs at DDR5 5600 continuously?

The CL46 latency at 5600 MT/s sets the timing boundary, and the 1.10 V registered 4Rx4 organisation defines the maximum sustainable throughput per channel.

How much heat and power do the 1.1 V DDR5 RDIMMs produce under all-day load?

Each module operates at 1.1 V without a heat spreader, so total power draw scales with the twelve 64 GB sticks and the server's airflow handles the resulting heat.
