  • CL11 latency ensures quick memory access for demanding workloads

Capacity and Role

This 16GB DDR3 module is built for servers that require registered ECC memory. It suits administrators upgrading or repairing compatible platforms where data integrity and stability take priority over raw bandwidth.

Build Integration

The registered buffer reduces electrical load on the memory controller, allowing higher module counts per channel. Its 1.35V operation lowers power draw compared to standard 1.5V DDR3, freeing thermal headroom in dense chassis. The module fits DDR3 RDIMM slots keyed for PC3-12800 signalling.

Thermals and Power

Running at 1.35V keeps heat output modest under typical server workloads. Passive airflow across the DIMM area is usually sufficient; no active cooling on the module itself is required. Power consumption scales with capacity and frequency, staying within standard DDR3 limits.

Questions about this item

What is the CAS latency limit that affects sustained throughput on this DDR3 1600 module?

The module runs at CL11, so each column access adds 11 cycles before data is returned under continuous load.

How much heat and power does the 1.35 V registered ECC DIMM produce during all-day operation?

At 1.35 V the DIMM draws less current than standard 1.5 V DDR3, reducing heat output in a fully populated server chassis.

Which server board features must already be present to use this registered ECC memory?

The motherboard needs DDR3 slots that support registered ECC modules and a memory controller able to address 16 GB per DIMM.
