4GB DDR4 2400 ECC RDIMM

This 4GB DDR4 2400 registered DIMM adds error-correcting memory to compatible servers and workstations. It suits administrators who need to expand capacity on platforms that require registered modules with ECC support. The module runs at 1.20V and carries a CL17 latency rating.

288-pin registered form factor

The stick uses a 288-pin DDR4 DIMM interface and presents a 1Rx8 organisation to the memory controller. Registered buffering reduces electrical load on the motherboard, freeing the platform to populate more slots without signal degradation. Verify that your system specifies DDR4 RDIMM support before installation.

Sustained ECC operation

Error-correcting code runs continuously during workloads, detecting and correcting single-bit errors without halting the system. Registered buffering maintains signal integrity across extended sessions, while the 1.20V standard voltage keeps power draw predictable under constant load. Quality testing validates reliable performance over time.

Questions about this item

How does the CL17 latency affect sustained throughput on this DDR4 2400 module?

The CL17 timing at 2400 MHz sets the baseline access delay; under sustained loads the registered buffer adds one cycle, so real-world bandwidth settles near the PC4-19200 rating.

What thermal or power behaviour should I expect when this 1.20 V ECC RDIMM runs continuously in a populated server chassis?

At 1.20 V the module stays within standard DDR4 power limits; the registered design shifts electrical load to the buffer chip, keeping DIMM temperatures low even during all-day workloads.

Which motherboard slot and chipset combination is required for this 288-pin 1Rx8 registered DIMM to function?

A DDR4 RDIMM slot with a server-class chipset that supports ECC and registered memory is required; consumer boards without registered-DIMM support will not post with this module.
