Kit composition and purpose

This kit contains two 4GB DDR4 DIMMs for a total of 8GB. It is built for desktop systems that require 288-pin unbuffered non-ECC modules. Buyers who need ECC error correction or registered buffering should select a different product line.

Capacity and headroom

The paired modules deliver 8GB at 2400 MHz with CL17 timings and 1.2V operation. A 64-bit operating system is required to address more than 4GB. All installed memory will run at the speed of the slowest module or the processor limit.

Deciding specification

Each stick is a 2Rx8 dual-rank device using the CM512642400DIMM part number. The dual-rank organisation and 288-pin DDR4 interface determine whether the motherboard and CPU memory controller can support the kit.

Questions about this item

Will these 2400MHz CL17 2Rx8 DDR4 DIMMs downclock to match the slowest module in my system?

Yes, the supplier notes that all memory in the system will run at the slowest performance of the installed modules or CPU capability.

How can I confirm both 4GB modules are recognised at 2400MHz CL17 after installation?

Check the BIOS or UEFI memory information screen; it should show 8GB total at DDR4-2400 with 17-17-17 timings and 1.2V operation.

What is included in the 2-piece kit and is any extra hardware needed?

The kit contains two 4GB 288-pin DDR4 DIMMs; no additional hardware is required for installation.
