Server-Specific 16GB Kit

This OWC kit provides 16GB of DDR3L ECC registered memory in a matched pair of 8GB modules. It is built for Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X servers. The modules run at 1600MHz with CL11 latency at 1.35V. They use a 240-pin RDIMM form factor with a 1Rx4 rank configuration.

For Workstation and Server Builds

This memory suits administrators upgrading or repairing the listed Dell PowerEdge platforms where ECC registered DIMMs are required. It will not work in standard desktop computers or consumer motherboards that only accept unbuffered non-ECC modules. Buyers needing unbuffered memory or higher capacities per module should look elsewhere.

Integration Into Compatible Chassis

Each 240-pin RDIMM installs directly into the server's DDR3L memory slots without additional hardware. The registered buffer reduces electrical load on the memory controller, allowing the platform to populate more slots reliably. The low 1.35V operation helps maintain thermal headroom inside dense rackmount enclosures.

Questions about this item

Will these 240-pin DDR3L RDIMMs work in my Dell PowerEdge C6220 server?

Yes, the kit is validated for Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X servers.

Can I mix these registered ECC modules with the unbuffered memory already in my C8220X?

No, registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered modules.

How can I confirm the kit is running at 1600 MHz CL11 after installation?

Check the BIOS memory information or use a system utility such as dmidecode to verify DDR3L 1600 PC3L-12800 CL11 operation.
