256GB DDR5 4800 ECC RDIMM kit

This kit provides 256GB of DDR5 server memory across 16 registered DIMMs, each rated at 4800 MT/s with CL40 latency and 1.1V operation. It targets IT teams deploying or expanding Dell PowerEdge R860 rack servers that require ECC protection and registered signal integrity for mission-critical workloads.

Verify DDR5 RDIMM slot count and population rules

Confirm the R860 has at least 16 DDR5 RDIMM slots and consult the server’s memory population guide for supported 1Rx8 configurations. The modules are 288-pin registered DIMMs without heat spreaders, so ensure airflow meets Dell’s thermal specifications for fully populated banks.

Sustained load stability with ECC and registration

All modules undergo rigorous stress testing under load to verify reliability during continuous operation. Registered buffering and on-die ECC maintain data integrity across extended compute cycles, while 1.1V operation keeps power draw consistent across the full 16-module array.

Questions about this item

Does the kit include all 16 DDR5 modules or must any be purchased separately?

The kit contains sixteen 16 GB DDR5 RDIMM modules for a total of 256 GB; nothing else is required to reach that capacity.

Why choose the CL40 1.10 V 1Rx8 version over other DDR5 speeds or ranks?

CL40 at 1.10 V with 1Rx8 organisation matches the Dell PowerEdge R860 qualified specification, ensuring registered ECC operation at the rated 4800 MT/s.

What does the PC5-38400 rating mean once the memory is installed in the R860?

PC5-38400 confirms each module runs at 4800 MT/s with CL40 latency, delivering the bandwidth and error-correction the R860 expects for registered DDR5 workloads.
