Capacity and Configuration

This 32GB kit delivers four 8GB DDR4 modules running at 2400MHz with CL17 timing. It is built for owners of the listed ASRock motherboards who need a matched set to fill every slot and reach the board's 64GB ceiling.

Who This Suits and Who Should Look Elsewhere

Builders upgrading an A320M Pro4, AB350 Pro4, AB350M Pro4, B250 Pro4, B250M Pro4, B450 Pro4 or B450M Pro4 will install these sticks without configuration changes. Buyers who need ECC error correction, registered modules, speeds above 2400MHz or a capacity larger than 64GB total cannot use this kit.

What the Bundle Changes

Four identical sticks enable quad-channel population on the supported boards, removing the guesswork of mixing modules. The package contains only the memory sticks; no heat spreaders, cables or software utilities are included.

Questions about this item

My ASRock B450M Pro4 board has four DIMM slots — will this 32 GB kit fill all of them?

Yes, the kit contains four 8 GB modules for a total of 32 GB, matching the four 288-pin slots on each listed ASRock motherboard.

Can I keep my existing DDR4 modules and add this CL17 2400 MHz kit alongside them?

Mixing modules with different speeds or timings forces the system to run at the slowest common settings; for reliable operation install the full 4×8 GB kit as a matched set.

After installation, how can I confirm the memory is running at 2400 MHz with CL17 timings?

Open the BIOS or a tool such as CPU-Z and verify the DRAM frequency reads 2400 MHz (PC4-19200) and the timings show 17-17-17 at 1.2 V.
