A-Tech 16GB DDR3 1866MHz ECC RDIMM 2Rx4 for Samsung M392B2G70BM0-CMA M392B2G70DM0-CMA Server Memory

SKU CH-014P-099YH

16 GB DDR3 ECC registered DIMM for Samsung M392B2G70BM0-CMA and M392B2G70DM0-CMA at 1866 MHz with CL13 latency and 1.5 V

  • Capacity16GB
  • SpeedDDR3 1866 (PC3 14900)
  • CAS LatencyCL13
  • Voltage1.50V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 16GB capacity expands server memory headroom for larger workloads
  • DDR3 1866MHz speed delivers PC3-14900 bandwidth for responsive data access
  • ECC registered design detects and corrects errors to protect data integrity
  • 2Rx4 organisation with Samsung chipset ensures stable signal quality
  • 5V standard voltage matches DDR3 platform power requirements

Compatible Samsung Server Replacement

This 16GB DDR3 1866MHz ECC RDIMM is built as a direct replacement for Samsung modules M392B2G70BM0-CMA and M392B2G70DM0-CMA. It uses a registered 2Rx4 layout with Samsung chipset and runs at the standard 1.50V DDR3 voltage. The module fits 240-pin DIMM slots in compatible server and workstation platforms.

Suited For Verified Samsung Part Numbers

This module suits administrators upgrading or repairing systems qualified for the listed Samsung part numbers. Builders whose motherboards require unbuffered UDIMMs, different rank configurations, or voltages other than 1.50V cannot use this registered DIMM. Systems that do not support ECC registered memory should select a different module type.

Registered 2Rx4 ECC At CL13 Latency

The CAS latency is rated at CL13 for DDR3 1866 (PC3-14900) operation. This timing is fixed by the module SPD and must match the platform memory controller requirements. Buyers should confirm the target system accepts CL13 registered ECC modules before purchasing.

Questions about this item

How can I confirm the module is running at 1866 MHz with CL13 after installation?

Enter the BIOS or UEFI and check the memory frequency and CAS latency fields; they should read 1866 MHz and CL13. You can also run a tool like CPU-Z or dmidecode to verify the SPD reports DDR3-1866 at 1.5 V with ECC registered operation.

What comes in the box and do I need any extra parts to install it?

The package contains one 16 GB DDR3 1866 MHz ECC RDIMM (240-pin, 2Rx4) built with Samsung chipset. No additional cables, brackets or heat-spreaders are required — just an available registered DIMM slot on a compatible server or workstation motherboard.

I see two Samsung part numbers listed — M392B2G70BM0-CMA and M392B2G70DM0-CMA — which one should I order?

Both part numbers refer to the same 16 GB DDR3-1866 ECC RDIMM 2Rx4 specification. This single A-Tech module is a compatible replacement for either Samsung MPN, so you simply order this one SKU regardless of which original label is on your existing stick.
