16GB DDR3 1866MHz ECC RDIMM for Supermicro Servers

This 16GB DDR3 1866MHz ECC registered DIMM is built for Supermicro servers that require registered memory with error correction. It uses a Samsung chipset in a 2Rx4 dual-rank configuration and runs at the standard 1.5V DDR3 voltage. The module is certified for Supermicro systems under part number MEM-DR316L-SL02-ER18.

240-pin RDIMM installation fits standard server

The 240-pin registered DIMM inserts into compatible DDR3 RDIMM slots on qualified Supermicro motherboards. Registered buffering means the module presents a lighter electrical load to the memory controller, which is required for multi-DIMM server configurations. Mixing registered and unbuffered DIMMs will prevent the system from booting, so verify the platform requires registered memory before installing.

16GB capacity supports virtualization

A single 16GB module at DDR3 1866MHz with CL13 latency provides headroom for running multiple virtual machines or memory-intensive databases on supported platforms. The dual-rank 2Rx4 organization maximizes density per slot, though total system capacity remains limited by the motherboard's maximum supported memory and available DIMM slots. Systems requiring more than 16GB per channel will need additional modules.

Questions about this item

How can I verify the 16GB DDR3 1866MHz ECC RDIMM is recognised at the correct 1866 MT/s speed and CL13 latency after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 1866 MT/s with CAS latency 13; the registered ECC module will also report its 2Rx4 organisation and 1.50 V operating voltage there.

What is included with the Supermicro Certified MEM-DR316L-SL02-ER18 module and what must be sourced separately?

The box contains one 16GB Samsung M393B2G70QH0-CMA RDIMM (240-pin, 2Rx4, ECC registered); any additional DIMMs, memory risers or cooling brackets required by your server chassis are not included.

Which capacity and rank configuration should I choose for a Supermicro system needing 16GB DDR3 1866MHz registered ECC memory?

Select the 16GB 2Rx4 module (MPN MEM-DR316L-SL02-ER18) — it matches the certified Samsung M393B2G70QH0-CMA specification for DDR3 1866 registered ECC at 1.50 V.
