16GB DDR4-2400 ECC Registered Module

This 16GB DDR4 module runs at 2400 MT/s with CL17 latency and 1.20V operation. It uses a 288-pin RDIMM form factor with a 1Rx4 rank layout and on-die ECC for data integrity. The registered buffer reduces electrical load on the memory controller in multi-module configurations.

Suited for multi-slot server boards needing

The registered design and ECC support make it appropriate for platforms that require buffered modules for stability across populated channels. Builders using consumer desktop boards or laptops that accept only unbuffered non-ECC UDIMMs cannot use this module.

Fits 288-pin DDR4 RDIMM slots on compatible server

Installation requires a motherboard with registered DDR4 DIMM slots and a CPU or chipset that supports ECC and registered memory. The single-rank organisation leaves additional ranks available per channel where the platform allows, helping maximise total capacity within the system's slot count.

商品問答

Does this 288-pin DDR4 module require a motherboard that supports registered ECC memory?

Yes, the module is registered with ECC and needs a server-class board that enables both features for the 16 GB stick to function correctly.

Can I mix this CL17 2400 MT/s stick with slower DDR4 modules already in my system?

The memory controller will run all installed modules at the speed and latency of the slowest one, so adding this PC4-19200 module to slower DDR4 will down-clock the new stick.

How can I verify the module is running at DDR4 2400 with CL17 after installation?

Check the BIOS memory information screen or a utility such as CPU-Z; it should report 2400 MT/s, CAS 17 and 1.20 V for this 1Rx4 registered DIMM.
