Server ECC RDIMM Kit

This OWC kit provides 64GB of DDR5 ECC registered memory in a matched pair of 32GB modules. It is built for the Dell PowerEdge R760xd2 server platform and runs at 4800 MT/s with CL40 latency at 1.1V. The 2Rx8 organization and 288-pin form factor match the system's registered DIMM slots. Workstations and standard desktops cannot use this memory type.

Registered ECC Benefits

The registered buffer reduces electrical load on the server memory controller, allowing stable operation with high module counts. On-die ECC corrects single-bit errors to protect data integrity in critical workloads. JEDEC and RoHS compliance ensures the modules meet industry specifications for server deployment. The kit replaces Dell part numbers AC239378 and SNPW08W9C/32G for direct compatibility.

Platform Verification Required

Confirm the target system is a PowerEdge R760xd2 before ordering, as registered ECC RDIMMs are physically incompatible with unbuffered or load-reduced memory slots. The server must support DDR5 4800 registered DIMMs at 1.1V with 2Rx8 rank configuration. Mixing this kit with any non-registered or LRDIMM modules will prevent the system from booting.

Questions sur cet article

Will the 2Rx8 ECC registered DIMMs need replacement after a certain number of write cycles?

DDR5 ECC registered memory does not wear out from write cycles like flash storage; the modules are rated for continuous server operation and carry a limited lifetime warranty.

What thermal limit appears first when the kit runs at 4800 MT/s under sustained load?

The JEDEC-specified 1.1 V operating voltage keeps power draw low, so the platform's DIMM-slot airflow limit is reached before any module thermal threshold.

How much heat and noise does the 64 GB kit add when the PowerEdge R760xd2 runs all day?

The modules have no heat spreader and draw minimal power at 1.1 V, so they add negligible heat and zero acoustic noise; system fans remain the only audible source.
