Server Memory Kit for Dell PowerEdge R6625

This 32 GB kit contains two 16 GB DDR5 4800 RDIMM modules built for the Dell PowerEdge R6625 rack server. Registered ECC operation protects data integrity in mission-critical workloads. The 1.10 V modules run at CL40 latency and use a 288-pin form factor with 1Rx8 organization.

Sustained Load Behaviour

ECC correction and registered buffering keep the memory subsystem stable during continuous enterprise workloads. Major OEM DRAM from Samsung, Micron or Hynix is stress-tested under load before shipment. The modules have no heat spreader, so airflow in the server chassis manages thermals during extended operation.

Pre-Installation Checks

Verify that the Dell PowerEdge R6625 memory slots accept 288-pin DDR5 RDIMM modules and support 1.10 V operation. Confirm the system BIOS is current enough to recognise 16 GB registered ECC DIMMs at 4800 MT/s. Ensure the chassis provides adequate airflow across the bare modules for thermal management.

Questions about this item

Does the 1.10 V DDR5 kit draw noticeably more power under continuous load than lower-voltage modules?

The kit operates at the standard DDR5 1.10 V, so its power draw matches the JEDEC baseline for 4800 MT/s registered DIMMs.

What motherboard slot and firmware support are required for these 288-pin RDIMMs to function?

A DDR5-compatible server motherboard with 288-pin RDIMM slots and BIOS support for 1Rx8 ECC registered modules is needed.

Can the 1Rx8 registered DIMMs share memory channels with existing DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds on the same channel is not recommended; the system will clock all modules to the slowest common settings.
