System-specific DDR4 module for ASRock B460 boards

This 16 GB DIMM is built to match the ASRock B460 Phantom Gaming 4, Pro4, Steel Legend and B460M Steel Legend motherboards. It delivers 2400 MHz speed with CL17 timing at 1.2 V in a single unbuffered non-ECC stick.

Verify your motherboard model

The module is validated only for the four listed ASRock B460 boards and fits a 288-pin DDR4 slot. Your system must run a 64-bit operating system to address more than 4 GB of memory. Mixed modules will operate at the slowest installed speed.

Adds 16 GB to a four-slot platform

The board supports up to 128 GB across four sockets, so this stick leaves room for three more modules. Matched-pair installation is recommended for best throughput, but single-stick upgrades are supported. All memory will run at the lowest common speed.

Questions about this item

What comes in the box and is anything else required to install the CM2048642400DIMM?

The package includes one 16 GB DDR4 2400 MHz CL17 2Rx8 288-pin DIMM. No extra parts are needed; the module fits directly into a compatible ASRock B460 motherboard slot.

Should I choose this 16 GB stick or look for a different capacity for my B460 board?

This 16 GB module works with the four-slot B460 boards listed, which support up to 128 GB total. Add a second identical stick for dual-channel performance, or fill all four slots to reach the maximum capacity.

What does the 2400 MHz rating mean once the memory is installed in my system?

The module runs at DDR4 2400 (PC4 19200) with CL17 timing at 1.2 V. If mixed with slower memory, all modules will operate at the lowest speed present.
