Samsung 16GB DDR3-1866 ECC Registered DIMM

This Samsung M393B2G70DB0-CMA module provides 16GB of DDR3 server memory operating at 1866 MT/s with a CAS latency of CL13. It uses a 2Rx4 registered design with ECC Chipkill error correction and runs at the standard 1.5V. The single 240-pin DIMM is sold new without a heat spreader.

Suited for servers needing registered ECC DDR3

This module fits systems that require registered DIMMs with Chipkill ECC and a 2Rx4 organisation at the DDR3-1866 speed grade. It is not for platforms that accept only unbuffered non-ECC UDIMMs or that require a different DDR generation, voltage, pin count or rank configuration.

The registered ECC Chipkill 2Rx4 organisation

The registered buffer and Chipkill ECC are mandatory for compatible chipsets; unbuffered or standard ECC modules will not work in the same slots. Verify that your server specifies registered DDR3-1866 RDIMMs with a 2Rx4 layout before purchasing.

Questions sur cet article

How much heat and power does the 1.50 V 1866 MHz registered module draw under continuous load?

The module operates at the standard DDR3 voltage of 1.50 V and the rated speed of 1866 MHz; registered DIMMs of this class typically draw a few watts per stick and run warm but within normal server thermal limits.

What motherboard slot and chipset features are required to run this 240-pin DDR3 RDIMM?

A 240-pin DDR3 DIMM slot that supports registered ECC memory is required; the board must accept 2Rx4 modules and provide the PC3-14900 data rate.

Will this 2Rx4 ECC Chipkill stick work in a system that already has single-rank DDR3 DIMMs installed?

Mixing ranks is generally supported on server platforms that qualify 2Rx4 modules; the memory controller will address each rank independently at the common 1866 MHz speed.
