OWC 1R3D32R416GB 16GB DDR3 1333 ECC Registered RDIMM memory upgrade

ECC Registered Server Memory

This 16GB DDR3 1333 module is an ECC registered RDIMM built for Supermicro X8DT6, X8DTE, X8DTG, X8DTH and X8DTi series motherboards. It targets administrators extending the service life of existing workstation or server platforms that require registered error-correcting memory. The part replaces Supermicro MEMDR316LSL05ER13 and will not operate in standard desktop systems or alongside unbuffered DIMMs.

240-Pin DDR3 Form Factor

The module uses a 240-pin DDR3 interface at 1.5V with CL9 latency and a 2Rx4 organisation. Because it is registered, the memory controller sees a reduced electrical load, allowing larger total capacities on supported server boards. No heat spreader is fitted, so airflow across the DIMM slots handles cooling in typical rack or tower chassis. Mixing this registered stick with unbuffered memory is not supported.

Single-Module Upgrade Kit

The package contains one 16GB RDIMM, letting you add capacity in 16GB increments without purchasing matched pairs. OWC tests every module in-house and backs the part with a limited lifetime warranty and free technical support. The advanced replacement programme ships a replacement before the original is returned, reducing downtime for critical server workloads.
