Server memory kit for Dell PowerEdge R7425

This 64GB kit uses two 32GB DDR4 2666 ECC registered DIMMs built for the Dell PowerEdge R7425. It targets IT teams expanding capacity in that specific server platform. Buyers needing non-ECC memory or a different form factor cannot use this kit.

Thermals power and noise

Modules run at 1.20V without heat spreaders, relying on the server's directed airflow for cooling. Registered buffering and ECC add negligible power draw under normal load. Silent operation is inherent because the DIMMs have no moving parts.

Build integration and slot usage

Each 288-pin RDIMM occupies one DDR4 slot and presents a 2Rx4 organisation at CL19. The pair adds 64GB across two channels, leaving remaining slots free for further expansion. Compatibility is validated for the PowerEdge R7425; other systems are not guaranteed.

Questions about this item

How do I install the 288-Pin DDR4 RDIMM modules in the PowerEdge R7425, and what step is often missed?

Power off the server, open the chassis, align each 288-Pin DDR4 RDIMM with the slot key, press firmly until the ejector clips lock, then verify in BIOS that both 32GB modules are recognised at 2666 MT/s.

What maintenance or replacement will the ECC RDIMM kit need over its service life?

The modules have no moving parts and no heat spreader; they require no scheduled maintenance. Replace a stick only if the system logs correctable ECC errors that exceed the platform threshold.

What limit appears first when the 64GB kit runs sustained workloads at 1.2V?

The DDR4 2666 CL19 timing and 1.2V voltage set the bandwidth ceiling; sustained throughput cannot exceed the PC4-21300 rating regardless of cooling or load duration.
