8GB DDR4 2666 DIMM for ASRock boards

This 8 GB DDR4-2666 module is built for the listed ASRock motherboards. It suits owners of an A320M-DVS R4.0, B360M-HDV, B360M-ITX/ac, Fatal1ty X470 Gaming-ITX/ac or Fatal1ty Z370 Gaming-ITX who want a straightforward capacity increase. The single stick delivers 8 GB at 1.2 V with CL19 timings. Buyers needing ECC or registered memory should look elsewhere.

Check motherboard model and free slots

Confirm your exact board model matches one of the five names above before ordering. The platform supports a maximum of 32 GB across two DIMM slots, so verify how many slots are already occupied. A 64-bit operating system is required to address more than 4 GB of memory. All installed modules will run at the speed of the slowest stick or the CPU limit.

Single stick enables dual-channel when paired

The package contains one 288-pin unbuffered DIMM without a heat spreader. Adding a second identical stick lets the board run in dual-channel mode for higher bandwidth. Mixing brands is possible but every module will drop to the lowest common speed and timing. The manufacturer backs the module with a limited lifetime warranty against defects.
