Dell PowerEdge R7625 server memory kit

This 64GB kit contains four 16GB DDR5 4800 registered ECC RDIMMs validated for the Dell PowerEdge R7625 rack server. It targets IT teams upgrading memory capacity in that specific platform without mixing module types.

Capacity and headroom for virtualised workloads

The 64GB total provides headroom for multiple virtual machines, container clusters or in-memory databases running on the R7625. Workloads that exceed 64GB will require additional DIMM slots or higher-density modules to scale further.

Thermals noise and power draw in normal use

Modules operate at 1.1V without heat spreaders, relying on the server's directed airflow for cooling. Registered buffering and ECC add minimal latency overhead while maintaining signal integrity under sustained load.

Questions about this item

Will the 4800 MHz DDR5 kit run at its rated speed alongside existing DDR5 modules already installed in the R7625?

The kit is rated at DDR5 4800 with CL40 latency and 1.10V. The R7625 will clock all populated slots to the lowest common speed, so mixed modules settle at the slowest kit's frequency.

How can I confirm the 64 GB kit is detected and operating with ECC after installation?

Enter the system BIOS or iDRAC interface; total memory should show 64 GB at 4800 MT/s with ECC status reported as active or enabled.

Does the 4 x 16 GB package include heatsinks or any extra cables?

The modules are bare 288-pin RDIMMs without heat spreaders. No cables, brackets or additional accessories are supplied.
