Dell PowerEdge R7425 DDR4 ECC Kit

This 16 GB kit contains two 8 GB DDR4 2666 registered DIMMs with ECC and a CAS latency of CL19. It operates at 1.2 V and uses a 288-pin RDIMM form factor designed for Dell PowerEdge R7425 servers. The modules are single-rank 1Rx8 and built with major OEM DRAM chips.

Verify R7425 Slot Population Rules

Check the server manual for the exact memory population order and maximum supported capacity per channel. Confirm that the system BIOS is updated to a version that recognises 2666 MT/s registered ECC modules. Ensure the existing configuration does not mix registered and unbuffered DIMMs, as this prevents boot.

Fills Two DIMM Slots In R7425 Chassis

The kit occupies two DDR4 slots inside the PowerEdge R7425, leaving remaining slots available for future capacity expansion. Registered ECC operation adds data integrity for virtualisation and database workloads. The 1.2 V rating matches the platform's standard DDR4 voltage rail without requiring additional power configuration.

Questions about this item

Does the kit include only the two 8 GB modules or are any tools or cables supplied?

The package contains the 16 GB kit as two 8 GB DDR4 2666 ECC RDIMM modules; no tools, cables or other accessories are included.

Should I choose the 2666 MHz CL19 1.2 V version or look for a different speed or latency?

This kit is built to the Dell PowerEdge R7425 specification of DDR4 2666 CL19 at 1.2 V; selecting a different speed or latency would deviate from the validated configuration.

What does the 2666 MT/s rating actually deliver once the modules are installed in the R7425?

The memory runs at the server-rated 2666 MT/s with ECC error correction and registered buffering, providing the validated throughput and stability for the PowerEdge R7425 platform.
