Dell PowerEdge R7425 64GB ECC Kit

This 64GB kit contains eight 8GB DDR4 2666 registered DIMMs built for the Dell PowerEdge R7425 server. ECC and registered buffering protect data integrity in multi-socket workloads. IT teams upgrading capacity in validated Dell platforms will find the modules drop into the qualified memory list without extra qualification steps.

Eight 1Rx8 modules at CL19 1.20V

The eight single-rank 1Rx8 modules run at PC4-21300 with CL19 latency and 1.20V operation. Registered signalling adds one cycle of command buffering so the memory controller stays stable when all channels are populated. The kit fills eight slots; buyers who want more storage than 64GB must look beyond this configuration.

288-pin RDIMM form factor for Dell servers

Each stick uses the standard 288-pin DDR4 RDIMM edge connector and operates without heat spreaders to fit Dell's airflow design. No extra cooling hardware is required beyond the server's stock fans. Builders who need a second card or different form factor cannot use this kit in those roles.

Questions about this item

Will the 2666 MHz DDR4 RDIMMs downclock automatically if I keep slower DDR4 ECC modules in the other slots of my PowerEdge R7425?

Yes, the server memory controller will negotiate a common speed so all installed DDR4 modules run at the lowest supported frequency, preserving stability across the full 64 GB kit.

How can I verify the 8x8 GB ECC RDIMM kit is operating at CL19 1.20 V after installation?

Enter the system BIOS or iDRAC interface; the memory information screen will show each 8 GB module running at 2666 MT/s, CAS 19, 1.20 V with ECC active.

Does the MR21300-818K8 package include eight individual 288-pin RDIMMs or do I need to buy extra modules to reach 64 GB?

The kit contains eight 8 GB RDIMMs for a total of 64 GB; no additional modules are required to populate the supported slots.
