Dell R7625 Server Memory Kit

This 1.5TB kit contains twelve 128GB DDR5 RDIMMs built for the Dell PowerEdge R7625. Registered ECC modules with 4Rx4 organisation provide the density and error correction required by virtualised workloads and large databases.

Sustained Load Behaviour

Operating at 4800MT/s with CL40 latency and 1.10V, the modules maintain rated speed under continuous enterprise traffic without thermal throttling. ECC and registered buffering preserve data integrity during extended compute runs.

Build and Connectors

Bare 288-pin DIMMs without heat spreaders rely on server chassis airflow for cooling. The kit matches Dell R7625 slot population rules, so installation follows the platform memory guide without adapter cables or special tools.

Questions about this item

How much power does the 1.5TB kit draw at its rated 1.10V across all 12 modules running continuously?

Each 128GB DDR5 RDIMM operates at 1.10V; total draw depends on the server's memory controller and workload, not on the modules alone.

What server platform must I already have to install this 12x128GB DDR5 4800 CL40 registered ECC kit?

The kit is validated for the Dell PowerEdge R7625 rack server; the motherboard must support 288-pin DDR5 RDIMM slots and 4Rx4 registered ECC modules.

Will these 4800 CL40 modules run stably alongside any existing DDR5 RDIMMs I keep in the same R7625?

Mixing ranks, speeds or latencies can prevent the system from posting; Dell recommends populating all 12 slots with identical 4Rx4 CL40 modules for guaranteed operation.
