  • ECC registered design protects data integrity in server workloads
  • 32 GB kit (4 × 8 GB) expands memory capacity for virtualisation
  • DDR3L 1600 CL11 at 1.35 V lowers power draw versus standard DDR3
  • 240-pin RDIMM form factor fits Supermicro 6027 and 6037 series
  • Replaces Supermicro MEMDR380L part numbers for drop-in compatibility

Server-grade DDR3L ECC RDIMM kit

This OWC kit supplies 32 GB of DDR3L 1600 CL11 registered ECC memory across four 8 GB modules. The 240-pin RDIMMs operate at 1.35 V and are validated for Supermicro SuperServer 6027 and 6037 series platforms. It is built for workloads that demand error correction and registered signalling.

Suited for qualified Supermicro servers

The modules fit Supermicro SuperServer 6027B, 6027PR, 6027R, 6027TR and 6037R systems that specify DDR3L registered ECC DIMMs. Builders who need unbuffered memory, a different DDR generation, or compatibility with consumer motherboards cannot use this kit. It also cannot be mixed with unbuffered modules in the same system.

Registered ECC with 1Rx4 organisation

The decisive specification is the registered ECC design with 1Rx4 rank structure, which matches the memory controller requirements of the listed Supermicro servers. Systems that require unbuffered DIMMs or a different rank configuration will not accept these modules.

Questions about this item

Does my Supermicro SuperServer 6027R need four free 240-pin DDR3L slots to install this 32 GB kit?

Yes — the kit contains four 8 GB registered DIMMs and each one occupies a single 240-pin DDR3L slot, so four empty slots are required.

Can I keep my existing Supermicro MEMDR380LSL10ER16 modules and add this OWC 1Rx4 kit alongside them?

No — this kit is ECC registered memory and the manufacturer states it cannot be mixed with unbuffered modules; all installed DIMMs must be registered.

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

Check the BIOS memory information or a hardware utility such as CPU-Z; it should report 1600 MHz speed, CL11 latency and 1.35 V voltage for each module.
