OWC 64GB (2x32GB) DDR3L 1600 ECC Registered RDIMM memory upgrade

SKU CH-QR0W-Y9QVN

Adds 64 GB of DDR3L 1600 ECC registered memory across two 32 GB modules for Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X servers

  • Capacity64GB (2 x 32GB)
  • Type240-Pin DDR3L ECC RDIMM
  • SpeedDDR3L 1600 (PC3L 12800)
  • CAS LatencyCL11
  • Voltage1.35V

Capacity 64GB (2 x 32GB)

  • ECC registered design protects data integrity in servers
  • 64GB kit with two 32GB modules expands capacity
  • DDR3L 1600 speed at 1.35V reduces power draw
  • JEDEC and RoHS compliant for warranty-safe upgrades
  • Validated for Dell PowerEdge C6220, C6220 II, C8000, C8220, C8220X

Server-grade DDR3L ECC kit

This OWC upgrade kit delivers 64GB of DDR3L 1600 ECC registered memory in a matched pair of 32GB modules. It runs at 1.35V with CL11 latency and uses a 240-pin RDIMM form factor built to JEDEC and RoHS standards. The kit targets Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X platforms that require registered ECC DIMMs.

Workstation and server builders only

The modules suit administrators extending the life of compatible PowerEdge servers or assembling new configurations that demand registered ECC memory. They will not work in standard desktop boards, consumer laptops or any system that accepts only unbuffered non-ECC DIMMs. Buyers needing unbuffered memory or a different voltage should look elsewhere.

64GB total across two slots

Two 32GB 4Rx4 modules provide 64GB of capacity, filling two DIMM slots and leaving remaining slots free for further expansion within the platform limit. The registered design and ECC function maintain data integrity under sustained multi-threaded workloads. Headroom ends when the server's maximum supported memory or slot count is reached.

Questions about this item

Which Dell PowerEdge servers will accept this 240-pin DDR3L 1600 ECC Registered kit?

The kit is validated for Dell PowerEdge C6220, C6220 II, C8000, C8220 and C8220X systems.

Can I add these modules alongside existing unbuffered DDR3L DIMMs in the same server?

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

How do I confirm the 64 GB kit is running at 1600 MHz with CL11 timings after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify speed, voltage and CAS latency.
