What it is and who it’s for

This A-Tech 16GB DDR3 module runs at 1333MHz with PC3-10600 timing and CL9 latency. It is an ECC registered DIMM built on Samsung chipset and operates at the standard 1.5V. The 4Rx4 organisation targets servers and workstations that require registered memory with error correction.

What to check before ordering

Verify that your system accepts DDR3 registered DIMMs with a 240-pin interface and supports 4Rx4 modules at 1.5V. Confirm the motherboard or server manual lists PC3-10600 speed and ECC capability. This module will not fit or function in platforms that require unbuffered or non-ECC memory.

Behaviour under sustained load

The registered design and ECC function maintain data integrity during continuous workloads typical of server environments. Standard 1.5V operation keeps power draw predictable over long periods. Quality assurance testing aims to deliver stable throughput without the errors that can accumulate in non-ECC configurations.

Questions about this item

What comes in the box and is anything else needed to install this 16GB DDR3 ECC RDIMM?

The package contains one 16GB DDR3 1333MHz PC3-10600 ECC registered DIMM with Samsung chips. No extra parts are required; the module plugs directly into a compatible 240-pin DDR3 server slot.

How do I decide between the Samsung M393B2K70CM0-CH9 and M393B2K70DM0-CH9 versions this module replaces?

This single A-Tech module is a compatible replacement for both Samsung part numbers, so you do not need to choose between them; it matches the 16GB, 4Rx4, 1.5V specification common to either original.

What does the 1333MHz PC3-10600 rating mean for actual server performance?

The module runs at DDR3-1333 with a peak transfer rate of 10600 MB/s and CL9 latency, delivering the rated bandwidth and error-correction required by registered DDR3 server platforms.
