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.

Questions about this item

What does the PC3-10600 1333 MHz DDR3 interface limit this module to in real use?

The DDR3 PC3-10600 standard caps the data rate at 1333 MT/s with CL9 timing at 1.5 V, so the module cannot run faster than 1333 MHz regardless of the motherboard.

What physical slot and clearance does the 240-pin 16 GB RDIMM require?

It needs a standard 240-pin DDR3 DIMM socket; the registered design adds a buffer chip but keeps the same height as a regular DDR3 module, so no extra clearance is required.

How is the module installed and what step do builders often miss?

Align the notch with the key in the 240-pin slot, press straight down until both retention clips click, then verify in BIOS that the system sees the full 16 GB at 1333 MHz and that ECC registered mode is active.
