16GB DDR3-1600 ECC registered module

This 16GB Samsung module runs at DDR3 1600 (PC3 12800) with CL11 latency and 1.50V operation. It uses a 240-pin form factor and a 2Rx4 registered design with on-die ECC. The component targets servers and workstations that require registered memory with error correction.

Sustained throughput and error handling

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry detects and corrects single-bit errors without halting the system. CL11 timing at 1600 MT/s delivers steady bandwidth for multi-threaded workloads that keep all ranks active.

DDR3 platform constraints

The 240-pin DDR3 interface limits maximum module density and signal rate compared to newer generations. Registered DIMMs require a compatible chipset and cannot be mixed with unbuffered memory in the same channel. Voltage is fixed at 1.50V with no lower-voltage profile defined.

Questions about this item

Will the 1.50 V DDR3 1600 registered DIMMs add noticeable heat or fan noise in a server running 24/7?

At 1.50 V the modules draw standard DDR3 power; registered buffering shifts electrical load to the memory controller, so thermals stay comparable to other DDR3 1600 ECC RDIMMs in the same chassis.

Does my motherboard need 240-pin DDR3 slots that support ECC and registered signalling for this 16 GB kit to work?

Yes — the module is a 240-pin DDR3 SDRAM with ECC and registered buffering, so the board must provide DDR3 ECC RDIMM support.

Can I install this CL11 1600 stick alongside slower CL9 DDR3 1600 ECC registered modules already in the system?

The memory controller will run all populated slots at the slowest common timing, so the CL11 module will operate at CL9 when mixed with CL9 sticks.
