Server Memory Upgrade

This 8GB DDR3 registered DIMM is built for servers and workstations that require ECC error correction. It replaces Samsung M392B1K70DM0-CF8, M393B1K70BH1-CF8, M393B1K70CH0-CF8 and M393B1K70DH0-CF8 modules. The 240-pin form factor fits standard DDR3 slots. Buyers needing unbuffered desktop memory or higher DDR generations cannot use this module.

Capacity and Headroom

The single 8GB module runs at 1066MHz with a PC3-8500 rating and CL7 latency. Registered buffering and 2Rx4 organisation allow the memory controller to address larger total capacities across multiple slots. Workloads that exceed the 8GB per module limit will require additional DIMMs to scale further.

Thermals Noise and Power

Standard 1.5V DDR3 voltage keeps power draw within normal limits for registered server memory. Passive operation produces no fan noise and adds minimal heat to a chassis with adequate airflow. The module is tested for reliable continuous operation in typical server environments.

Questions about this item

Will this DDR3 1066MHz ECC RDIMM work alongside other DDR3 1066MHz registered modules in my server?

Mixing modules of the same speed, voltage, and registered type is generally supported by server platforms, but the system will run all memory at the lowest common specifications.

How can I confirm the module is running at 1066MHz with ECC active after installation?

Check the BIOS memory information screen or use a system utility such as CPU-Z to verify the reported speed of 1066MHz and that ECC status shows as enabled.

Does the 240-pin DIMM arrive alone or with any extra brackets or cables?

The package contains the single 8GB DDR3 1066MHz ECC RDIMM module only; no brackets, cables, or additional accessories are included.
