64GB DDR5-4800 ECC RDIMM Kit

This 64GB kit contains four 16GB DDR5 registered DIMMs rated at 4800MT/s with CL40 latency. Each module operates at 1.10V and uses a 1Rx8 organisation with on-die ECC. The 288-pin RDIMM form factor is built for Dell PowerEdge R6625 rack servers.

Suited for Dell PowerEdge R6625 capacity upgrades

IT teams expanding memory in a PowerEdge R6625 will find the correct speed, voltage and registered ECC profile in this kit. Builders working on other platforms or needing unbuffered UDIMMs, lower latency or higher frequencies should select a different part.

Registered ECC with 1Rx8 organisation

The modules are registered ECC RDIMMs with a 1Rx8 rank structure, a requirement for the target server's memory controller. Systems that accept only unbuffered memory or a different rank configuration cannot use this kit.

Questions about this item

Does this 288-pin DDR5 RDIMM kit fit the Dell PowerEdge R6625 memory slots?

The kit uses the standard 288-pin DDR5 RDIMM form factor that matches the R6625 DIMM sockets.

What is the correct order for installing the four 16 GB modules in the R6625?

Populate the slots following the server's documented channel sequence — usually one module per channel first — so the registered ECC modules initialise in the right order.

When should the ECC registered modules be replaced in a production R6625?

Replace them if the system logs correctable ECC errors that climb over time or if a module fails the built-in memory diagnostics during POST.
