Server memory upgrade

This 16 GB DDR4 ECC registered DIMM is built for workstations, servers and compatible NAS systems that require registered memory. It operates at 2400 MHz with a CAS latency of CL17 and runs at the standard 1.2 V. The module is not compatible with standard desktop computers or unbuffered memory configurations.

288-pin registered form factor

The 288-pin RDIMM layout fits DDR4 server slots that accept registered modules. Because it lacks a heat spreader, it sits flush in dense memory arrays where taller modules would interfere with airflow or adjacent components. ECC and registered buffering work together to detect and correct single-bit errors while reducing electrical load on the memory controller.

16 GB capacity per module

Each stick delivers 16 GB in a dual-rank 2Rx8 organisation, making it the single specification that determines whether this part matches the slot population rules of your platform. Verify that your system supports registered ECC DDR4 at this density before purchase.

Questions about this item

What DDR4 standard and speed does this PC4-19200 module run at?

It operates at the JEDEC DDR4 2400 standard with a CL17 latency and 1.2V voltage.

Which slot type and form factor does this 288-pin RDIMM require?

It needs a standard 288-pin DDR4 DIMM slot that supports registered ECC memory in a server or workstation board.

How is the module seated, and what alignment step is often missed?

Align the notch on the gold edge with the key in the slot, press straight down until both side clips click, and confirm the module sits fully vertical.
