16GB DDR3 1866MHz ECC Registered RDIMM

This 16GB DDR3 module runs at 1866MHz with CL13 latency and 1.50V operation. It uses a 2Rx4 dual-rank Micron chipset and a 240-pin registered form factor designed for server platforms. ECC error correction and Supermicro certification ensure data integrity and validated compatibility.

Who this suits and who should look elsewhere

System administrators upgrading Supermicro-certified servers that require DDR3 1866MHz registered ECC memory will find this module a direct fit. Buyers whose platforms demand unbuffered UDIMM modules, different voltage levels, or higher per-slot densities cannot use this registered RDIMM.

The specification that decides compatibility

The registered RDIMM form factor with ECC and 2Rx4 organisation is the single attribute that determines whether this module works in a given server; the motherboard must explicitly support registered ECC DDR3 at 1866MHz.

Questions about this item

Does my motherboard need 240-pin DDR3 slots that support registered ECC modules?

Yes, this module is a 240-pin DDR3 RDIMM with ECC and registered buffering, so the board must accept registered ECC DDR3 memory.

Can I mix this 1866 MHz CL13 module with slower DDR3 ECC RDIMMs I already have?

The system will run all modules at the speed and timings of the slowest installed kit, so this 1866 MHz CL13 stick will down-clock to match older DDR3 ECC RDIMMs.

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

Check the BIOS memory information or use a tool such as CPU-Z; it should report 1866 MHz, CL13, 1.50 V and show ECC enabled for the 16 GB module.
