Dell PowerEdge R6625 Server Memory Upgrade

This NEMIX RAM module delivers 128GB of DDR5 capacity in a single registered DIMM. It is built for IT teams expanding memory in Dell PowerEdge R6625 rack servers running virtualisation, databases or high-performance computing workloads. The ECC registered design protects data integrity in mission-critical environments.

288-Pin RDIMM Form Factor With 4Rx4 Organisation

The module uses the standard 288-pin DDR5 RDIMM connector and a quad-rank 4Rx4 layout, allowing dense capacity per slot without proprietary mounting. No heat spreader is fitted, so airflow in the server chassis passes directly over the DRAM packages. Installation follows the usual DIMM-slot procedure described in the system manual.

DDR5 4800 Speed and CL40 Latency Limits

Operating at 4800 MT/s with PC5-38400 bandwidth and CL40 CAS latency, the module runs at the base DDR5 data rate defined for the platform. The 1.1V voltage is fixed by the DDR5 specification for registered DIMMs. Performance scales with the memory controller capabilities of the host server; the module does not support higher speeds or lower latencies than those stated.

Questions about this item

What speed does the DDR5 4800 interface actually run at in a Dell PowerEdge R6625?

The module is rated for DDR5 4800 (PC5-38400); the server's memory controller determines the final operating speed.

Will the 288-pin RDIMM fit the R6625's memory slots without a heat spreader?

Yes, the 288-pin DDR5 RDIMM form factor matches the R6625 DIMM slots; the module has no heat spreader.

Do I need to configure anything in the BIOS after installing this 4Rx4 ECC registered module?

Install the RDIMM with the server powered off; the system typically detects the ECC registered module automatically.
