Dell PowerEdge R6615 compatible DDR5 ECC RDIMM kit

This 32 GB kit contains two 16 GB registered DDR5 modules rated at 4800 MT/s with CL40 latency and 1.10 V operation. The modules use 1Rx8 organisation and ECC error correction for data integrity in server workloads. They are validated for the Dell PowerEdge R6615 rack server.

Registered buffering and ECC protect data integrity

Registered buffering reduces electrical load on the memory controller so the system remains stable with high module counts. ECC detects and corrects single-bit errors before they affect applications. The 1Rx8 layout keeps signal paths simple for reliable operation at 4800 MT/s.

Verify DDR5 RDIMM support and slot population rules

Confirm the motherboard accepts DDR5 registered DIMMs and check the qualified vendor list for 1Rx8 modules at 4800 MT/s. Ensure enough 288-pin slots are free for both sticks and review the server manual for required population order.

Questions about this item

Will the ECC RDIMM modules need replacement once their rated 4800 MT/s speed is no longer sufficient for the workload?

The kit runs at 4800 MT/s with CL40 latency; replacement is only required if the platform demands a higher data rate or capacity beyond the 32 GB provided.

Does the single-rank 1Rx8 organisation or the 1.10 V supply limit sustained throughput before thermal throttling occurs?

Each 16 GB module is 1Rx8 at 1.10 V with no heat spreader; the registered buffer and ECC add latency overhead, so the memory controller typically reaches its bandwidth ceiling before the DRAM itself overheats.

How much extra noise or heat do the registered ECC sticks add when the Dell PowerEdge R6615 runs continuously?

The modules operate at 1.10 V without heat spreaders, so they rely on the server’s existing airflow; they add negligible acoustic noise and only marginal thermal load compared with unbuffered DIMMs.
