Dell PowerEdge R7425 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR4 2666 registered DIMMs built for the Dell PowerEdge R7425. ECC and registered buffering protect data integrity in the server chassis.

Sustained-load behaviour

Modules are stress tested under load before shipping so they maintain rated 2666 MT/s throughput during continuous server workloads. The 1.20 V operating voltage keeps power draw steady over long runs.

CL19 latency at 2666 MT/s

CAS latency of 19 cycles at DDR4 2666 determines response time for memory-bound tasks. Buyers who need lower latency or higher speed should select a different specification.

Questions about this item

How much power does the 2666 MHz DDR4 kit draw at its rated 1.2 V?

Each 16 GB module runs at 1.2 V, so the pair stays within standard DDR4 power limits for registered DIMMs in a Dell PowerEdge R7425.

What must the server already have to accept these 288-pin RDIMMs?

The R7425 needs free DDR4 RDIMM slots that support ECC registered memory and a BIOS revision that recognises 16 GB dual-rank modules.

Will the CL19 registered sticks work beside older DDR4 ECC modules already in the R7425?

Yes, provided the existing DIMMs are also DDR4 ECC registered; the system will run all channels at the slowest common speed and latency.
