Server ECC RDIMM Upgrade

This 16GB DDR3 1600 ECC RDIMM module is built as a compatible replacement for the Samsung M393B2G70BH0-CK0Q9. It targets administrators who need registered memory with error correction for server or workstation platforms that accept DDR3 DIMMs. The single 2Rx4 rank stick installs in a standard 240-pin slot and runs at the standard 1.5V voltage.

Thermals Power And Noise

DDR3 RDIMM modules operate without active cooling and draw only the power required by the memory controller at 1.5V. Under normal server workloads the sticks run silently and add negligible heat to the chassis airflow. No fan or heatsink considerations are needed beyond standard case ventilation.

Compatibility Verification And Support

The manufacturer highlights that every module undergoes quality assurance testing before shipment and that buyers should verify their system's supported memory specifications prior to purchase. A-Tech backs the part with a lifetime warranty and provides US-based technical support for installation questions. No additional software or accessories are bundled.

Questions about this item

How do I install this 240-pin DDR3 RDIMM and what step is often missed?

Align the notch on the 240-pin DDR3 module with the slot key, press firmly until both side clips click, then verify the system recognises the full 16 GB at 1600 MHz in BIOS.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; if a correctable error count rises or the module fails, replace it with another DDR3 1600 ECC RDIMM of matching 2Rx4 rank and 1.5 V specification.

What limit appears first when this registered memory runs sustained workloads?

The CL11 latency at 1600 MHz and 1.5 V voltage set the bandwidth ceiling; sustained loads will saturate throughput before thermal limits become an issue.
