Capacity 16GB (2 x 8GB)

  • ECC registered design protects data integrity in server workloads
  • Dual 8 GB modules deliver 16 GB total capacity for memory-hungry applications
  • DDR3L 1600 CL11 at 1.35 V reduces power draw versus standard DDR3
  • 240-pin 1Rx4 RDIMM form factor fits Supermicro 1027 and 2027 series
  • Replaces Supermicro MEMDR380L part numbers for validated compatibility

Server memory kit

This OWC kit supplies 16 GB of DDR3L ECC registered memory in two 8 GB modules for Supermicro SuperServer 1027 and 2027 series systems. It is built for workstations, servers, NAS devices and routers that require registered DIMMs with error correction.

Compatibility check

Verify that your motherboard accepts 240-pin DDR3L RDIMMs at 1.35 V and supports registered ECC modules. This memory will not work in standard desktop boards or alongside unbuffered DIMMs, so confirm the platform matches the listed SuperServer series before ordering.

Sustained operation

The modules run at PC3L-12800 speed with CL11 latency and operate without a heat spreader, relying on server chassis airflow for cooling. ECC registration maintains data integrity during continuous workloads, and JEDEC-compliant construction ensures stable voltage delivery over long periods.

Questions about this item

What modules are included and do I need anything else to install them?

The kit contains two 8 GB DDR3L 1600 CL11 1.35 V ECC registered DIMMs for a total of 16 GB; no extra parts are required.

How do I decide between this 16 GB kit and other capacity options?

Choose this 2 x 8 GB kit when your Supermicro 1027 or 2027 series server has free 240-pin slots and you want 16 GB of registered ECC memory.

What does the PC3L-12800 rating mean once the memory is running in my server?

PC3L-12800 indicates a peak transfer rate of 12 800 MB/s at 1600 MHz with CL11 latency, giving registered ECC bandwidth for workloads on the supported Supermicro platforms.
