Dell PowerEdge R7425 Memory Upgrade

This 16GB DDR4 2666 ECC RDIMM is built for the Dell EMC PowerEdge R7425 server. It targets system administrators and IT teams who need registered error-correcting memory to maintain data integrity in production workloads. The module runs at 1.2V with CL19 latency and uses a 288-pin form factor.

Installation Notes

The RDIMM inserts into the server's standard DDR4 DIMM slots and is keyed to prevent misalignment. Most issues arise when mixing registered and unbuffered modules or when the total population exceeds the platform's rank-per-channel limit. Follow the R7425 service manual for correct slot sequence and torque the retention levers fully.

Pre-Order Checks

Confirm the server currently runs DDR4 registered ECC memory and that the BIOS is updated to the latest revision listed by Dell for the R7425. Verify the available DIMM slots match the 2Rx8 rank configuration and that the memory operating voltage is set to 1.2V in the firmware. Ensure the operating system supports the total capacity after the upgrade.

Questions about this item

How can I confirm the 16GB DDR4 2666 module is running at CL19 1.2V after installing it in my PowerEdge R7425?

Enter the system BIOS or iDRAC interface after boot; the memory configuration screen will show each DIMM operating at 2666 MT/s with CL19 timings and 1.2V.

What does the package contain and is anything else required for installation in the R7425?

The box includes one 16GB 288-pin ECC RDIMM; no extra cables, brackets or cooling parts are needed for the server memory slots.

Should I choose the 1Rx8 or 2Rx8 rank version for the R7425?

This module is built as 2Rx8; the R7425 memory population rules treat 2Rx8 DIMMs as standard registered ECC parts, so select this 16GB 2Rx8 kit to match the validated configuration.
