32GB DDR5 ECC Registered Module

This 32GB DDR5 4800 ECC Registered RDIMM is built for Dell PowerEdge HS5610 and HS5620 servers. It operates at 1.1V with a CL40 latency and a 2Rx8 rank configuration. The module uses a 288-pin form factor and is not compatible with standard desktop computers or unbuffered memory types.

Sustained error-correcting operation

ECC Registered technology detects and corrects single-bit errors during continuous workloads, protecting data integrity in server and workstation environments. Registered buffering reduces electrical load on the memory controller, helping maintain stability when multiple modules are populated across channels. The 4800MHz JEDEC speed delivers consistent throughput without relying on overclocking headroom.

Direct slot installation

The 288-pin DDR5 module installs directly into compatible RDIMM slots on the HS5610 or HS5620 motherboards. No heat spreader is present, so airflow across the PCB is unimpeded. Installation fails when mixed with unbuffered or load-reduced DIMMs, or when placed in systems that do not support ECC Registered memory. Verify the server model and memory population rules before adding this module.

Questions about this item

Does the 1.1 V DDR5 4800 RDIMM stay cool during continuous server workloads?

The module runs at 1.1 V with no heat spreader, so airflow through the Dell PowerEdge HS5610 or HS5620 chassis handles cooling during sustained operation.

What must the Dell PowerEdge HS5610 or HS5620 already support to use this 288-pin ECC registered DIMM?

The system needs DDR5 RDIMM slots that accept 2Rx8 registered ECC modules at 4800 MT/s and 1.1 V.

Can this CL40 2Rx8 module sit in the same channel as the original Dell AC239378 memory?

Yes — it replaces Dell part AC239378 and matches the same DDR5 4800 CL40 2Rx8 1.1 V registered ECC specification, so it can populate the same channel.
