System-specific DDR4 upgrade

This 4 GB DDR4-2400 module is built to match the exact timing and voltage requirements of ASRock A320M and AB350M motherboards. It arrives as a single 288-pin DIMM rated CL17 at 1.2 V.

Fits listed ASRock boards only

Builders with the supported A320M, A320M-DGS, A320M-HDV, A320M-ITX, AB350M or AB350M-HDV models can install it directly. Systems that require ECC, registered modules or a different pin count will not accept this stick.

32 GB two-slot ceiling

Each board accepts a maximum of 32 GB across two slots, so this 4 GB stick leaves one slot free for a future matching module. Buyers needing more than 32 GB total capacity must choose a different platform.

Questions about this item

What motherboard slot does the CM512642400DIMM 288-pin DDR4 module require?

The module fits a standard 288-pin DDR4 DIMM slot on the listed ASRock A320M or AB350M boards.

Will this 2400 MHz DDR4 stick run at its rated speed if I keep my existing slower DDR4 modules installed?

The board will clock all installed DDR4 modules down to the speed of the slowest stick, so the new module will match the older modules' frequency.

How can I confirm the CM512642400DIMM is detected at 2400 MHz with CL17 timings after installation?

Check the BIOS memory information screen or a tool such as CPU-Z; it should report 2400 MHz DDR4 with 17-17-17 timings at 1.2 V.
