512GB DDR5 ECC RDIMM kit for Dell PowerEdge R660XS

This registered ECC memory kit delivers 512GB across sixteen 32GB modules built for the Dell PowerEdge R660XS server platform. It targets IT teams running virtualisation clusters, large databases or memory-heavy analytics workloads that require data integrity and full platform validation.

Sixteen 32GB modules at DDR5-4800 CL40

Each 2Rx4 module operates at 1.10V with a CAS latency of 40, providing 38400 MT/s bandwidth per stick. The 512GB total capacity supports dense VM consolidation and in-memory datasets, while the registered buffer maintains signal integrity across all populated slots. Workloads exceeding 512GB or demanding lower latency than CL40 will require a different configuration.

288-pin RDIMM form factor with no heat spreaders

Modules install directly into the R660XS memory slots without additional clearance for heatsinks, freeing airflow for CPU coolers. The kit relies on the server's qualified memory list for compatibility; systems not validated for this part number or requiring unbuffered DIMMs cannot use these modules.

Questions about this item

Will the 16 32GB DDR5 4800 CL40 modules run alongside any existing DDR5 RDIMMs I keep in the Dell PowerEdge R660XS?

The 512GB kit fills 16 slots with identical 2Rx4 registered ECC modules at 1.1V. Mixing different ranks speeds or voltages can prevent the server from posting so matching the kit is recommended.

How can I confirm the 512GB DDR5 4800 kit is operating correctly after installation in the R660XS?

Enter the system BIOS or iDRAC and verify all 16 modules show 32GB each at 4800MT/s CL40 1.1V with ECC active. Run the built-in memory diagnostic to check for errors.

What comes in the box and do I need any extra parts for the Dell PowerEdge R660XS?

The package contains the 16 32GB DDR5 RDIMMs only. No heat spreaders cables or tools are included and the server itself supplies the required 288-pin slots and cooling.
