768 GB DDR5 4800 ECC RDIMM kit

This 768 GB kit contains six 128 GB DDR5 4800 registered DIMMs built for Dell PowerEdge R6615 rack servers. Each module runs at CL40 latency and 1.10 V, providing error-correcting memory capacity for virtualization hosts and database clusters. The registered design reduces electrical load on the server memory controller.

Sustained load behaviour with registered ECC

Registered buffering and on-die ECC keep data integrity intact during continuous multi-threaded workloads such as in-memory analytics or container orchestration. The 4Rx4 organisation spreads accesses across four ranks per module, helping the memory controller maintain throughput when all channels are populated. Operation at the standard 1.10 V limits thermal output inside dense 1U chassis.

Build quality and daily mounting implications

Modules use major OEM Samsung, Micron or Hynix DRAM without heat spreaders, relying on server airflow for cooling. The 288-pin RDIMM form factor fits only registered DDR5 server slots; it will not seat in unbuffered desktop or workstation boards. Each stick is stress-tested under load before shipping to confirm compatibility with the validated platform.

Questions sur cet article

Does the 1.10 V operating voltage help keep heat and power draw low during continuous server workloads?

The modules run at 1.10 V, which is the standard DDR5 voltage, so power consumption and thermal output stay within the normal range for 4800 MT/s registered DIMMs.

Must the motherboard support 4Rx4 registered ECC DDR5 RDIMMs for this kit to function?

Yes, the system needs DDR5 RDIMM slots that accept 4Rx4 registered ECC modules at 4800 MT/s; the kit is validated for the Dell PowerEdge R6615 platform.

Can the 288-pin DDR5 RDIMMs be mixed with older DDR5 modules of different rank or speed in the same server?

Mixing 4Rx4 CL40 4800 MT/s sticks with modules of other ranks or speeds is not recommended; the memory controller will down-clock to the slowest common settings and may disable multi-rank optimisations.
