512GB DDR5 RDIMM kit for Dell PowerEdge R6615

This 512GB kit contains four 128GB DDR5 registered DIMMs built for the Dell PowerEdge R6615. Each module runs at 4800 MT/s with CL40 latency at 1.1V. ECC and 4Rx4 organisation provide the data-integrity and density required by virtualization hosts and database servers.

Sustained-load behaviour with ECC registered DDR5

Registered buffering and on-die ECC keep signal integrity stable during continuous multi-threaded workloads. The 1.1V operating voltage limits thermal output while the 4800 MT/s data rate maintains throughput for memory-bound applications running around the clock.

Tool-free DIMM installation in a 288-pin slot

Modules seat vertically in the server's 288-pin DDR5 slots without cables or brackets. The 4Rx4 density means every slot is populated, so the memory configuration must match the platform's qualified vendor list; a mismatched population order will prevent the system from posting.

Questions about this item

How much power do the 1.1V DDR5 modules draw when the server runs continuously?

Each 128GB module operates at 1.10V, the standard DDR5 voltage, so total power scales with the 512GB capacity and the R6615 memory controller load.

What must the Dell PowerEdge R6615 already have for this 4x128GB kit to function?

The R6615 needs free 288-pin DDR5 RDIMM slots, a BIOS that supports 4Rx4 registered ECC modules, and a CPU memory controller rated for 4800 MT/s operation.

Can I mix these 4Rx4 CL40 RDIMMs with other DDR5 ranks already installed in the R6615?

Mixing ranks is possible if the R6615 BIOS supports heterogeneous population rules, but Dell's qualified configurations usually recommend identical 4Rx4 modules per channel for stability.
