Samsung DDR4 16GB registered ECC module

This Samsung DDR4 module provides 16 GB of registered ECC memory in a single 288-pin DIMM. It operates at 2400 MT/s with CL17 latency at 1.20 V. The 2Rx4 organisation and on-board register suit server platforms that require error correction and signal buffering.

Check motherboard support for registered ECC DDR4

Verify that your server board accepts registered ECC DDR4 DIMMs and can run at 2400 MT/s with CL17 timing. The module needs a 288-pin DDR4 slot and 1.20 V operation. Consumer desktop boards typically do not support registered memory, so confirm the platform before ordering.

Fits 288-pin DDR4 server slots.

Install the DIMM into a compatible 288-pin DDR4 slot on a server motherboard that supports registered ECC memory. The module draws 1.20 V and uses the on-board register to reduce electrical load on the memory controller. Using registered ECC here leaves standard unbuffered slots available for different memory types if the platform allows mixed populations.

Questions about this item

Does the single 16GB DDR4 2400 CL17 Registered ECC module ship alone or with extra parts?

The module ships as a single 288-pin DIMM; no heat spreader, cables or additional hardware are included.

When should I choose this 16GB 2Rx4 CL17 stick over a different capacity or rank?

Choose this 16GB 2Rx4 CL17 stick when your server needs Registered ECC DDR4-2400 at 1.20V and has a free 288-pin slot for a single module.

What does the DDR4-2400 PC4-19200 rating mean once the stick is installed in a server?

The module runs at 2400 MT/s with CL17 latency at 1.20V, delivering PC4-19200 bandwidth while the register and ECC maintain signal integrity and data accuracy.
