32GB ECC Registered DDR3 Kit

This 32GB kit contains two 16GB DDR3 1600 CL11 registered DIMMs built for Supermicro SuperWorkstation 5037A and 7047A systems. It targets administrators who need error-correcting memory in validated workstation or server platforms. The modules will not work in standard desktop computers and cannot be mixed with unbuffered memory.

240-Pin 1.5V Registered Modules

Each stick uses a 240-pin DDR3 interface at 1.5V with a 2Rx4 organisation and no heat spreader. The registered design places a buffer on the command bus to reduce electrical load on the memory controller, which is required by the supported Supermicro platforms. Installers must populate slots according to the system manual because registered DIMMs have specific population rules.

Two-Module Matched Pair

The kit ships as a matched pair of 16GB modules so the workstation can run in dual-channel mode without the user sourcing individual sticks. OWC tests every module in-house to JEDEC and RoHS standards and backs the kit with a limited lifetime warranty plus free technical support. The part number 1R6D32R4032P replaces Supermicro MEMDR316LHL01ER16 and MEMDR316LSL01ER16.

Questions about this item

What speed and latency does this DDR3 1600 CL11 kit run at in a Supermicro SuperWorkstation 5037A?

The modules operate at 1600 MHz with PC3-12800 bandwidth and a CAS latency of CL11 at the standard 1.5 V JEDEC voltage.

What physical slot and form factor do these 240-pin RDIMMs require?

Each 16 GB module uses a 240-pin DDR3 DIMM form factor and fits the registered DIMM slots on Supermicro SuperWorkstation 5037A and 7047A series boards.

How do I install this 2 x 16 GB ECC registered kit and what is the common mistake?

Power down, open the chassis, align the notch on each 240-pin RDIMM with the slot key, press firmly until both latches click, then verify the system detects 32 GB; the frequent error is mixing these registered modules with unbuffered DIMMs, which prevents boot.
