Server Memory Upgrade

This OWC 16GB DDR3L 1600 RDIMM delivers ECC registered memory for Supermicro X9QRi and X9SRD motherboards. The single module operates at 1.35V with CL11 latency and a 2Rx4 rank configuration. It uses a 240-pin form factor built to JEDEC standards.

Workstation and Server Builders

Suitable for administrators upgrading compatible Supermicro workstation, server, NAS or router platforms that require registered ECC DDR3L memory. Not for standard desktop PCs or laptops that use unbuffered non-ECC modules. Cannot be mixed with unbuffered memory in the same system.

Platform Compatibility Check

Verify your motherboard is a Supermicro X9QRi or X9SRD series model before ordering. Confirm the system accepts DDR3L registered ECC RDIMMs at 1600 MT/s and 1.35V. Check available 240-pin DIMM slots and the maximum supported capacity per slot.

Questions about this item

Does my Supermicro motherboard need to support ECC registered DDR3L memory for this module to work?

Yes, this 16GB module is DDR3L ECC Registered RDIMM and requires a motherboard that accepts registered ECC memory; it will not work in boards that only take unbuffered DIMMs.

Can I add this 16GB DDR3L 1600 CL11 RDIMM alongside existing unbuffered DDR3L DIMMs in my Supermicro X9SRD system?

No, registered and unbuffered memory cannot be mixed; all slots must use registered ECC modules for the system to operate correctly.

After installing the module, how can I confirm it is running at the correct 1600 MT/s speed and CL11 latency?

Enter the system BIOS or use a hardware-information utility; the memory details should show DDR3L-1600, CAS latency 11, 1.35 V operation and ECC registered mode.
