Dell PowerEdge R7425 upgrade kit

This 32 GB kit contains four 8 GB DDR4 2666 registered DIMMs built for the Dell EMC PowerEdge R7425 server. It targets administrators who need to expand memory capacity in that specific platform without mixing module types.

Registered ECC with 1Rx8 organisation

Each module is a 288-pin DDR4 RDIMM running at 1.20 V with CL19 latency and 1Rx8 chip organisation. The registered buffer and on-die ECC are the single specification that determines whether the server will accept the kit.

Fills four slots in matched sets

The kit occupies four DIMM slots as a matched quad, leaving remaining channels free for further expansion. It requires a motherboard that supports DDR4 RDIMM memory and draws standard 1.20 V power from the server's memory subsystem.

Questions about this item

What does the 2666 MT/s rating mean once the kit is installed in a PowerEdge R7425?

The modules run at DDR4 2666 (PC4 21300) speed, delivering that data rate when the server’s memory controller is configured for 2666 MT/s operation.

How does the 288-pin RDIMM interface and registered design affect what the system can use?

The 288-pin DDR4 RDIMM form factor with registered buffering and ECC is required by the R7425; the registered design reduces electrical load on the memory controller, allowing higher capacities per channel.

What physical space and power do the four 8 GB modules need to fit in the server?

Each module is a standard 288-pin DDR4 RDIMM without a heat spreader, operates at 1.2 V, and occupies one DIMM slot; four slots must be free in the R7425.
