  • CL13 latency at 1.50 V balances response and stability

Server-ready DDR3 memory module

This 32 GB Samsung module operates at DDR3 1866 with a CAS latency of CL13 and a voltage of 1.50 V. It is built for server platforms that require registered DIMMs. The load-reduced design reduces electrical load on the memory bus.

ECC Chipkill and heat spreader

On-board ECC Chipkill corrects multi-bit errors to protect data integrity in critical workloads. The integrated heat spreader helps maintain stable temperatures during sustained operation. The module uses a 4Rx4 organisation with major brand chipset components.

DDR3 1866 interface limits

The DDR3 1866 standard caps transfer rates at PC3 14900 bandwidth. Systems limited to lower DDR3 speeds will clock this module down automatically. Platforms that do not support load-reduced or ECC Chipkill registered DIMMs cannot use this memory.

Perguntas sobre este artigo

Will the 4Rx4 load-reduced ECC Chipkill module need firmware updates or scheduled replacement during its service life?

No firmware updates are required for this DDR3 1866 module; the 32 GB stick is built with a heat spreader and Major Brand Chipset components for long-term server operation.

What limit appears first when the 1.50 V CL13 memory runs at full 1866 MT/s load continuously?

The thermal ceiling of the 4Rx4 load-reduced design is reached before signal timing margins, so sustained throughput is capped by the module's ability to dissipate heat through its spreader.

How much heat and noise does the 32 GB DDR3 1866 stick produce inside a populated server chassis all day?

The module draws 1.50 V with a heat spreader but has no moving parts, so it adds only passive thermal load and zero acoustic noise to the chassis airflow.
