OWC 16GB DDR3 ECC Registered RDIMM

This OWC module provides 16GB of DDR3 1600 memory with CL11 latency and 1.5V operation. It uses a 240-pin RDIMM form factor with 2Rx4 organisation and built-in ECC registration. The part matches Lenovo 0A89483 specifications exactly.

For workstation and server upgrades only

Suitable for administrators extending the life of DDR3-based servers, workstations, NAS units or routers that require registered ECC memory. Not for standard desktop PCs or laptops, which cannot use registered modules. Buyers needing unbuffered memory or a different DDR generation must look elsewhere.

Fits DDR3 registered DIMM slots

Installs directly into 240-pin DDR3 RDIMM slots on compatible server or workstation boards. The registered buffer reduces electrical load on the memory controller, freeing headroom for larger total capacities. No heat spreader is fitted, so airflow in the chassis should be adequate for dense configurations.

Questions about this item

Does this 240-pin DDR3 RDIMM require a server or workstation motherboard that supports ECC registered memory?

Yes, the module is DDR3 1600 ECC registered and will only function in systems designed for registered DIMMs; standard desktop boards cannot use it.

Can I mix this 2Rx4 registered DIMM with any unbuffered DDR3 modules already installed?

No, registered and unbuffered memory cannot be mixed; all slots must use registered ECC modules for the system to operate correctly.

After installation, how do I confirm the 16 GB module is running at PC3-12800 CL11 1.5V?

Check the BIOS memory information or an OS tool such as dmidecode; it should report 1600 MT/s, CL11 timings and 1.5 V for this DIMM.
