OWC 16GB DDR3L ECC Registered RDIMM

This 16GB DDR3L 1600 CL11 module is built for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR series systems. It delivers registered ECC reliability for workstation and server workloads that demand data integrity. The single DIMM upgrades memory capacity without requiring paired modules.

Verify DDR3L registered ECC support before ordering

Your platform must accept 240-pin DDR3L RDIMMs at 1.35V with CL11 timing and 2Rx4 organisation. Standard desktop boards cannot use registered ECC memory and will not post with this module installed. Mixing this stick with unbuffered DIMMs is not supported and will prevent operation.

JEDEC compliant build with no heat spreader

The bare green PCB fits tight server DIMM slots where tall spreaders would block airflow or adjacent modules. Gold edge contacts meet 240-pin DDR3L specifications for consistent seating. OWC tests every unit in house to confirm stability under sustained server loads.

Questions about this item

Does the 240-pin DDR3L RDIMM arrive as a single 16 GB stick or do I need extra modules?

The upgrade is a single 16 GB DDR3L 1600 CL11 2Rx4 1.35 V ECC Registered RDIMM; no additional modules are included.

Should I choose the 16 GB 2Rx4 registered version or a different capacity for my Supermicro 7037A?

This 16 GB 2Rx4 registered DIMM matches the Supermicro 7037A, 7047AX and 7047GR specifications; select it when you need one 16 GB registered module.

What does the PC3L-12800 1600 CL11 rating mean once the DIMM is installed in a 7047GR workstation?

The module will run at 1600 MT/s with CL11 latency at 1.35 V, delivering ECC registered error correction for the 7047GR platform.
