Server-grade DDR3 ECC RDIMM

This OWC module provides 16GB of DDR3 1333 registered ECC memory on a 240-pin 1.5V stick. It is built for Supermicro SuperServer 5086B, 8026B and 8046B systems that require registered DIMMs. The single-rank 2Rx4 layout and CL9 timing match the original Supermicro part MEMDR316LSL05ER13.

Suited for compatible Supermicro servers

It fits administrators upgrading or repairing the listed SuperServer models where registered ECC DDR3 is mandatory. It will not work in standard desktop PCs, consumer laptops or any platform that only accepts unbuffered non-ECC memory. Builders needing unbuffered modules or a different DDR generation must choose another product.

Registered ECC DDR3 at 1333 MT/s

The module runs at PC3-10600 speed with CL9 latency and 1.5V voltage in a registered ECC configuration. This specification decides whether the part matches the motherboard's memory controller requirements. Verify that your SuperServer model expects registered ECC DDR3 before ordering.

Questions about this item

What server models must I already own for this 16GB DDR3 1333 ECC Registered RDIMM to work?

This module is validated for Supermicro SuperServer 5086B Series, 8026B Series and 8046B Series systems that accept 240-pin DDR3 ECC registered DIMMs.

Can I keep my existing unbuffered DDR3 DIMMs and add this registered 2Rx4 module alongside them?

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

How do I confirm the 16GB DDR3 1333 CL9 module is running at the correct speed after installation?

Check the BIOS memory information or OS tool such as dmidecode to verify the module reports 1333 MHz, CL9 latency and ECC registered status.
