Server-Specific DDR3L ECC Kit

This OWC kit supplies 32GB across four 8GB DDR3L 1600 CL11 registered DIMMs built for Supermicro SuperServer 2027, 2028 and 4027 series systems. Each module runs at 1.35V with 1Rx4 organisation and ECC error correction. The 240-pin form factor matches the factory slots in the listed SuperServer models.

Workstation and Server Upgrades Only

The registered ECC design suits administrators extending life on compatible Supermicro platforms or building new servers that require registered memory. It will not work in standard desktop boards, consumer workstations or any system that expects unbuffered DIMMs, and it cannot be mixed with unbuffered modules.

Steady Throughput Under Load

Registered buffering and ECC maintain data integrity during continuous multi-threaded workloads such as virtualisation, database serving or NAS duties. The 1.35V DDR3L voltage reduces heat output compared with standard DDR3, helping stability when all four slots are populated and the server runs sustained jobs.

Questions about this item

Does this kit require a Supermicro SuperServer motherboard with 240-pin DDR3L registered DIMM slots?

Yes, the modules are 240-pin DDR3L ECC registered DIMMs and are validated for Supermicro SuperServer 2027PR, 2027R, 2027TR, 2028UT and 4027GR series systems.

Can I mix these 1.35 V CL11 registered modules with any existing unbuffered DDR3L DIMMs in the same server?

No, the manufacturer states these registered modules cannot be mixed with unbuffered memory; all slots must use registered ECC DIMMs.

How can I confirm the kit is running at DDR3L 1600 CL11 after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify each module reports 1600 MT/s, CL11 latency and 1.35 V operation.
