Capacity and module type

This Samsung module provides 16GB of DDR3 memory in a 240-pin registered DIMM format. It is built for servers and workstations that require error-correcting code protection. The module operates at 1600MHz with a CAS latency of 11 and a low voltage of 1.35V.

Suitable systems and limitations

It suits administrators upgrading or repairing DDR3-era platforms that specifically support registered ECC memory and the 2Rx4 rank organisation. It will not work in desktop or laptop boards that accept only unbuffered non-ECC modules, nor in systems that cannot address registered DIMMs or that require a different pin count or voltage.

Deciding specification

The registered ECC design combined with DDR3 1600 speed and 1.35V operation is the single specification that determines compatibility; the motherboard must explicitly support registered error-correcting DDR3 at this voltage and frequency.

Questions about this item

Does the CL11 latency at DDR3 1600 stay consistent during long server workloads?

CL11 at DDR3 1600 keeps timing stable, and ECC corrects single-bit errors so data integrity is maintained throughout sustained use.

How much heat and power does the 1.35 V registered design produce in 24/7 operation?

The 1.35 V DDR3 voltage and registered buffering lower power draw and heat output compared with standard 1.5 V unbuffered modules during continuous operation.

Which motherboard slot and chipset support 240-pin DDR3 registered ECC memory?

This module fits a 240-pin DDR3 DIMM slot and requires a server-class chipset that supports registered ECC memory.
