OWC 32GB DDR3L ECC RDIMM Kit

This 32GB kit contains four 8GB DDR3L 1600 CL11 registered DIMMs built for Supermicro X9QRi and X9SRD motherboards. It targets server and workstation administrators who need error-correcting memory for 240-pin DDR3L slots. Standard desktop boards cannot use these registered modules, and they must not be mixed with unbuffered memory.

Capacity and headroom

The four-module layout fills four DIMM slots with 32GB total, suited to virtualization hosts, NAS appliances and router platforms that benefit from ECC integrity. Workloads exceeding 32GB or requiring higher frequencies than 1600 MT/s will need a different platform or larger modules.

Build and daily implications

Modules lack heat spreaders, relying on chassis airflow in 1U or tower server enclosures. The 1.35V DDR3L voltage reduces power draw compared to standard DDR3. Each stick uses a 240-pin registered interface keyed for server boards only, so physical installation is limited to compatible Supermicro X9 series systems.

Questions about this item

Will the 1.35 V DDR3L RDIMMs run alongside existing 1.5 V DDR3 modules in my Supermicro X9SRD?

No, registered ECC DDR3L cannot be mixed with unbuffered or 1.5 V DDR3; the board requires all slots to use identical registered DDR3L modules.

How can I confirm the 32 GB kit is detected at 1600 MHz CL11 after installation?

Check the BIOS memory information screen — it should show 32 GB total, DDR3L 1600, CL11, 1.35 V, registered ECC on all four channels.

Does the kit include four 8 GB RDIMMs or do I need to buy extra sticks?

The upgrade kit contains four 8 GB DDR3L 1600 CL11 1Rx4 240-pin registered ECC modules; no additional memory is required.
