Dell PowerEdge XE8640 memory kit

This 64GB kit contains two 32GB DDR5 RDIMMs built for the Dell PowerEdge XE8640 rack server. Registered ECC operation protects data integrity in multi-socket configurations. Modules run at 1.1V with a CL40 latency profile. The kit targets administrators expanding memory capacity on qualified Dell platforms.

Sustained workload behaviour

Registered buffering and on-die ECC maintain signal quality during continuous read-write cycles typical of virtualization and database tasks. The 4800 MT/s data rate delivers steady throughput without relying on short burst speeds. Dual-rank 2Rx8 organisation supports higher density per channel under prolonged load.

CL40 latency at DDR5 4800

The CAS latency of CL40 at 4800 MT/s determines how quickly the memory controller can access each column. This timing is fixed by the module SPD and cannot be tightened without platform support. Buyers needing lower latency must verify motherboard compatibility before purchase.

Questions sur cet article

How much power does the 1.1 V DDR5 4800 RDIMM kit draw under sustained load?

Each module runs at 1.10 V; total draw depends on the Dell PowerEdge XE8640 memory controller and workload, not on the kit alone.

What must the Dell PowerEdge XE8640 already have to accept this 288-pin ECC registered kit?

The server needs free DDR5 RDIMM slots that support 2Rx8 organisation and PC5-38400 speed; the kit itself is a direct plug-in upgrade.

Will the CL40 2Rx8 modules run at 4800 MT/s if the system currently uses slower DDR5 RDIMMs?

All installed DDR5 RDIMMs operate at the lowest common speed; the kit will downclock to match the existing modules.
