Supermicro Certified 16GB DDR3 RDIMM

This Supermicro Certified 16GB DDR3 1866MHz ECC Registered RDIMM uses Samsung M393B2G70DB0-CMA chips. It delivers 16GB capacity at PC3-14900 speed with CL13 latency and 1.50V operation. The 2Rx4 dual-rank 240-pin module suits servers and workstations requiring registered ECC memory.

For Supermicro systems needing DDR3 ECC Registered

It fits administrators upgrading compatible Supermicro platforms that accept 1866MHz DDR3 RDIMMs. It is not for systems requiring unbuffered UDIMMs, load-reduced LRDIMMs, or modules with different pin counts, voltages, or rank configurations. Buyers must verify their platform supports this exact specification before purchase.

2Rx4 dual-rank registered ECC organization

The 2Rx4 rank structure determines how the memory controller addresses the module and affects maximum population rules per channel. Systems limited to single-rank DIMMs or requiring specific rank-per-channel limits will not support this module. Match this organization to your motherboard qualified-vendor list for correct operation.

Questions about this item

Does my server need DDR3 RDIMM slots to accept this 240-pin module?

Yes, the module is a DDR3 RDIMM with a 240-pin form factor, so the motherboard must provide registered DDR3 DIMM slots.

Can I mix this CL13 1866 MHz stick with slower DDR3 ECC RDIMMs already installed?

The system will run all modules at the speed and timings of the slowest installed DIMM, so mixing is possible but overall memory bandwidth will drop to the lower spec.

How do I confirm the module is recognised as 16 GB ECC registered at 1866 MHz after installation?

Check the BIOS memory information or run a tool such as dmidecode; it should report 16 GB, DDR3-1866, registered ECC, and the Samsung M393B2G70DB0-CMA part number.
