Server ECC RDIMM for Dell PowerEdge

This OWC module is a 16GB DDR5 4800 CL40 ECC Registered DIMM built for Dell PowerEdge C6600, C6620, MX760C, R660 and R6615 servers. It targets administrators upgrading or repairing those specific platforms. It is not for desktop PCs, workstations that require unbuffered memory, or systems that need load-reduced DIMMs.

Standard 288-pin installation with no heat spreader

The module seats in a regular DDR5 RDIMM slot using the 288-pin interface and runs at 1.1V. Because it lacks a heat spreader, airflow in the chassis must be sufficient for bare DRAM. Mixing this registered ECC stick with unbuffered or load-reduced memory will prevent the system from posting.

1Rx8 single-rank organisation

The single-rank 1Rx8 layout determines how the memory controller addresses the module and affects maximum population rules for each Dell model. Buyers who need dual-rank density or a different rank-per-channel configuration should verify the server’s qualified vendor list before ordering.
