System-specific server memory

This OWC module is a 16GB DDR3L 1600 ECC Registered RDIMM built for Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X systems. It targets administrators who need to extend the service life of these platforms or add capacity during a new build. The module carries part number 1R6T32R416GB and replaces several Dell part numbers including A6761613 and SNP20D6FC/16G.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the Registered ECC design combined with a 2Rx4 rank structure. This memory will not work in standard desktop computers and cannot be mixed with unbuffered modules. It operates at 1.35V with CL11 latency and conforms to the PC3L-12800 speed grade.

240-pin DDR3L slot requirement

Installation requires an available 240-pin DDR3L DIMM slot that supports Registered ECC memory at 1.35V. The module has no heat spreader, so it fits in dense server chassis where taller modules would interfere with airflow. It frees a slot for additional capacity while maintaining the error-correction and signal integrity needed for server workloads.

Questions about this item

What does the 16 GB capacity mean for a Dell PowerEdge C6220 server?

A single 16 GB registered ECC module adds one rank pair to a channel, letting the C6220 address more virtual machines or larger databases without swapping to disk.

How does the PC3L-12800 rating limit real-world throughput on these servers?

PC3L-12800 caps the data rate at 1600 MT/s; the memory controller in the C6220, C8000 or C8220 series cannot push this DIMM beyond that ceiling.

Will the 240-pin RDIMM fit the memory slots in a Dell PowerEdge C8220X?

Yes — the 240-pin DDR3L registered form factor matches the DIMM sockets used across the C6220, C6220 II, C8000, C8220 and C8220X platforms.
