OWC 16GB DDR3 ECC Registered RDIMM

This OWC server memory module delivers 16GB of DDR3 1333 performance with CL9 latency and 1.5V operation. It uses a 240-pin registered DIMM form factor with 2Rx4 organisation and full ECC support. The module meets JEDEC and RoHS standards for reliable enterprise deployment.

For workstation and server upgrades only

This registered ECC memory suits administrators extending the life of compatible Dell platforms such as A6996789 or SNPMGY5TC/16G systems. It will not function in standard desktop computers or consumer motherboards. Builders needing unbuffered non-ECC modules for consumer hardware should select a different product type.

Registered ECC DDR3 1333 240-pin constraint

The registered buffer and ECC logic require a server or workstation chipset that explicitly supports registered DDR3 DIMMs. Mixing this module with unbuffered memory is not supported. Verify your platform documentation accepts registered ECC DDR3 1333 240-pin RDIMMs before purchase.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Power off the server, open the chassis, align the 240-pin module with the DDR3 slot, press firmly until the retention clips click, then enter the BIOS to verify the 16GB capacity and ECC registered status are detected.

What maintenance or replacement will this 16GB DDR3 ECC RDIMM need over time?

No scheduled maintenance is required; if a memory error occurs, run the server diagnostics to identify the faulty 2Rx4 module and replace it with another 16GB DDR3 1333 CL9 1.5V registered DIMM.

What limit appears first when this 1333 MHz RDIMM runs under sustained load?

The DDR3 1333 bus and CL9 latency set the throughput ceiling; sustained workloads will saturate the 10600 MT/s transfer rate before the 1.5V registered buffer becomes a bottleneck.
