4GB DDR4 2666 module for ASRock boards

This single 4GB DDR4 2666 stick is built for the listed ASRock motherboards including the A320M-DVS R4.0, B360M-HDV, B360M-ITX/ac, Fatal1ty X470 Gaming-ITX/ac and Fatal1ty Z370 Gaming-ITX. It runs at 1.2V with CL19 timing in a 2Rx8 unbuffered layout. The 288-pin DIMM carries a major-brand chipset and no heat spreader.

Replaces a missing or slower DDR4 stick

Adding this module upgrades a system that has an empty slot or a lower-speed DDR4 DIMM installed. The board supports up to 32GB across two sockets so the jump is worth it when you need more capacity for a 64-bit operating system or want matched-pair performance. All memory will run at the speed of the slowest module or the processor limit.

Suits owners of the named ASRock models

Builders with one of the compatible ASRock boards who need a single 4GB DDR4 2666 DIMM can use this kit. Buyers who need more than 32GB total capacity or who want a factory-matched pair for dual-channel operation should look at a different kit. Systems limited to 32-bit operating systems cannot address more than 4GB regardless of installed memory.

Spurningar um þessa vöru

Does the 288-pin DDR4 DIMM fit the ASRock B360M-HDV motherboard?

The module is a 288-pin DDR4 DIMM and the supplier lists the B360M-HDV among the compatible ASRock boards.

What BIOS setting or slot order is often missed when installing this 2666 MHz stick?

Install the stick in the primary DIMM slot first; if the board defaults to a lower speed, enable the XMP or DOCP profile in BIOS to reach 2666 MHz.

When should the 4 GB module be replaced if the system later needs more than 32 GB total?

The supported platform maximum is 32 GB across two sockets, so the 4 GB stick would need to be swapped once the workload exceeds that limit.
