Server-grade DDR4 RDIMM

This 16GB DDR4 3200 ECC registered DIMM targets workstations and servers that require error-correcting memory. It will not work in standard desktop platforms and must not be mixed with unbuffered modules. The 288-pin module runs at 1.2V with CL22 latency and a 2Rx8 organisation.

Build integration needs

The stick plugs into a 288-pin DDR4 slot and draws 1.2V from the motherboard. No heat spreader is fitted, so airflow across the PCB is necessary. Systems must support registered ECC memory; unbuffered consumer boards will not POST with this module installed.

Sustained-load behaviour

JEDEC-compliant timings and ECC correction maintain data integrity during continuous operation. Registered signalling reduces electrical load on the memory controller when multiple DIMMs are populated. The module is validated for long-term server workloads rather than short benchmark runs.

Questions about this item

What is the CAS latency that determines the minimum response delay under sustained workloads?

The module operates at CL22, which sets the timing floor for every access once the system is under continuous load.

How much power does the 16GB DDR4 3200 registered DIMM draw and does it need extra cooling when running all day?

It runs at the standard 1.2 V for DDR4 registered memory and has no heat spreader, so it depends on normal chassis airflow through the DIMM slots.

What motherboard slot type and memory architecture must the system already provide for this RDIMM to function?

The system needs a 288-pin DDR4 registered DIMM slot and a platform that supports ECC registered memory; standard desktop boards that only accept unbuffered modules will not work.
