32GB DDR5 ECC RDIMM kit

This 32GB kit contains two 16GB DDR5 registered DIMMs built for Dell PowerEdge R860 servers. The modules deliver error-correcting code protection and registered signalling for stable operation in multi-socket enterprise workloads. IT teams can deploy them to expand memory capacity in validated Dell platforms without proprietary lock-in.

Registered 288-pin design at 1.1V

Each module uses a 288-pin RDIMM form factor with 1Rx8 organisation and runs at the standard DDR5 1.10V voltage. The registered buffer reduces electrical load on the memory controller, allowing larger populations per channel in dense rack configurations. Absence of a heat spreader keeps the profile low for tight server chassis airflow paths.

Upgrades from lower-capacity DDR5 RDIMMs

The jump is worthwhile when virtualisation density, database buffer pools or analytics workloads exceed the current memory ceiling and the platform supports DDR5 4800 registered ECC. Systems limited to fewer DIMM slots or non-ECC memory cannot use this kit. Buyers needing higher frequencies or lower latencies should verify platform qualification before purchasing.

Questions about this item

What speed does the DDR5 4800 interface run at in this 288-pin kit?

The modules operate at DDR5 4800 (PC5-38400) with a CAS latency of CL40 at 1.10 V.

Will the 288-pin RDIMM height clear standard server heatsinks without a spreader?

These 288-pin RDIMMs have no heat spreader, so they fit the low-profile DIMM slots in the Dell PowerEdge R860 without clearance issues.

Which slot population order does the R860 manual require for a 2 x 16 GB registered kit?

Install the two 1Rx8 RDIMMs in the first channel of each processor socket, following the R860 memory-configuration guide for registered DIMMs.
