Supermicro Certified 16GB DDR3 RDIMM

This 16GB DDR3 module carries Supermicro certification for compatible server platforms. It operates at 1866MHz with CL13 latency and runs at the standard 1.50V DDR3 voltage. The registered design and ECC function help maintain data integrity under heavy workloads. Each unit is tested before shipment to confirm reliable operation.

Suited for registered ECC slots only

Systems that require registered DDR3 ECC RDIMMs with a 2Rx4 organisation can use this part. Builders whose boards accept only unbuffered DIMMs or non-ECC memory cannot install this module. The fixed 1866MHz speed and 1.50V voltage also rule out platforms limited to lower frequencies or different voltage rails. Verify the motherboard manual before ordering.

Single 16GB 2Rx4 DDR3 1866MHz registered ECC module

The decisive specification is the 2Rx4 registered ECC organisation combined with 1866MHz DDR3 speed. A board that supports this exact rank configuration and voltage will recognise the full 16GB capacity. If the platform demands a different rank layout, unbuffered signalling, or a non-ECC module, this DIMM will not function.

Questions about this item

Does this 240-pin DDR3 RDIMM require a server motherboard that supports registered ECC memory?

Yes, the module is a registered ECC DDR3 RDIMM, so the motherboard must accept registered error-correcting DIMMs and provide a 240-pin DDR3 slot.

Can I mix this CL13 1866 MHz module with slower DDR3 DIMMs already in my system?

The module runs at DDR3 1866 with CL13; if slower DDR3 DIMMs are present, the system will typically downclock all modules to the lowest common speed and latency.

How can I confirm the module is recognised at 1866 MHz with ECC active after installation?

Check the BIOS memory information or the operating system's hardware report; both should show 16 GB at 1866 MHz and indicate ECC registered operation.
