OWC 32 GB DDR3 ECC Registered RDIMM

This 32 GB DDR3 1600 module uses a 240-pin RDIMM form factor with 4Rx4 organisation and CL11 latency. It operates at 1.5 V and includes ECC error correction for data integrity. The part is validated for Supermicro SuperWorkstation 5037A and 7047A systems.

Suited for Supermicro workstation upgrades

Builders expanding memory in a 5037A or 7047A workstation will find this module compatible. It will not work in standard desktop PCs or consumer motherboards that require unbuffered non-ECC memory. Buyers needing unbuffered DIMMs or a different voltage should look elsewhere.

Straightforward DIMM installation

Align the notch on the 240-pin edge connector with the slot key and press firmly until the retention clips engage. The registered buffer adds a slight delay during POST, which is normal. Mixing this registered ECC module with unbuffered memory will prevent the system from booting.

Questions about this item

What system must I already own for this 32GB DDR3 1600 CL11 4Rx4 240-pin 1.5V ECC Registered RDIMM to work?

This module is validated for Supermicro SuperWorkstation 5037A Series and 7047A Series systems that accept DDR3 1600 registered ECC memory.

How does this registered ECC DDR3 1600 module behave alongside older unbuffered DDR3 DIMMs I may keep installed?

It cannot be mixed with unbuffered memory; the platform requires all slots to use registered ECC modules of matching specification.

How can I verify the 32GB DDR3 1600 CL11 4Rx4 240-pin 1.5V ECC Registered RDIMM is working as intended after setup?

Check the BIOS or OS memory report for 32GB capacity, 1600 MT/s speed, CL11 timings, 1.5V voltage and registered ECC status.
