16 GB DDR3 ECC RDIMM for Lenovo servers

This 16 GB DDR3 1333 MHz registered DIMM is built for Lenovo systems using part numbers 03X3813 and 0A89413. It targets administrators extending the life of existing DDR3 server platforms. The module delivers error-correcting code protection and registered signalling for multi-DIMM stability.

Tool-free DIMM slot installation

Installation follows standard 240-pin DDR3 keying; align the notch and press until the latches click. The registered buffer adds a clock cycle, so the module must not be mixed with unbuffered DIMMs. Systems that require unbuffered memory will not post with this part installed.

ECC Registered 2Rx4 organisation at 1.5 V

The single specification that decides fit is the 2Rx4 registered ECC organisation running at 1.5 V. Boards wired for unbuffered or non-ECC DDR3 cannot use this module. Verify the platform manual calls for registered ECC RDIMMs before purchase.

Questions about this item

How do I confirm the 16GB DDR3 1333 module is recognised at 1333 MT/s with ECC active after installation?

Boot the server and open the BIOS or UEFI memory information screen; it should show 16 GB running at 1333 MT/s, CL9, 1.5 V, with ECC enabled and the module reported as registered.

What ships with the OWC 1R3D32R416GB stick and is anything else required to install it?

The box contains only the 240-pin DDR3 ECC registered RDIMM; no cables, brackets or tools are included, and no extra parts are needed if the server has a free DDR3 RDIMM slot.

When should I choose this 16 GB 2Rx4 CL9 registered kit instead of a lower-capacity or unbuffered alternative?

Select this module when the server requires ECC registered DDR3 1333 memory, needs the 2Rx4 organisation for the memory controller, and you want a single 16 GB DIMM to match Lenovo part numbers 03X3813 or 0A89413.
