Dell PowerEdge R6615 128GB Kit

This 128GB kit contains four 32GB DDR5 registered DIMMs built for the Dell PowerEdge R6615 rack server. Each module runs at 5600 MT/s with CL46 latency at 1.1V. ECC and 2Rx4 organisation protect data integrity in multi-socket workloads.

Registered ECC RDIMM Operation

Registered signalling reduces electrical load on the server memory bus, allowing the R6615 to populate all slots at rated speed. On-die ECC corrects single-bit errors before they reach the CPU, keeping databases and virtualisation hosts stable under sustained load.

Suited For R6615 Capacity Expansion

Administrators filling the R6615 to its supported DIMM count with matched 32GB modules will gain maximum ranked capacity per channel. Buyers needing unbuffered UDIMMs, non-ECC memory, lower voltages or speeds other than 5600 MT/s should look at something else.

Questions about this item

Will the 2Rx4 RDIMM modules need replacement if the Dell PowerEdge R6615 firmware updates change memory timing requirements?

The kit uses standard DDR5 5600 CL46 timings at 1.1 V with ECC and registered buffers; firmware updates that stay within JEDEC DDR5 specs will not require module replacement.

Which limit appears first during sustained all-core workloads on the R6615 with this 128 GB kit?

The CAS latency of CL46 at 5600 MT/s sets the access-time floor; sustained throughput is bounded by the DDR5 5600 data rate and the registered buffer before thermal or power limits are reached.

How much heat and noise do the four 32 GB RDIMMs add when the R6615 runs 24/7?

Each module operates at 1.1 V without a heat spreader; the registered DDR5 design keeps per-DIMM power low, so the server’s existing airflow handles cooling without increasing fan speed.
