Compatible DDR4 kit for ASRock Z170 and Z270 boards

This 16 GB kit contains two 8 GB unbuffered DIMMs built to run at 2400 MHz with CL17 timing. It targets owners of the listed ASRock Fatal1ty motherboards who need a straightforward capacity increase without configuration hassle.

16 GB total with 64 GB platform ceiling

The two modules provide 16 GB of usable memory; the supported boards can accept up to 64 GB across four slots. Everyday multitasking and mainstream gaming sit well within this headroom, while heavy content-creation workloads or large virtual-machine sets will eventually require the remaining slots to be populated.

Low-voltage unbuffered modules run cool and quiet

Operating at 1.2 V with no heat spreader, the sticks add minimal thermal load and produce no audible noise. Power draw stays modest under normal desktop loads, leaving ample margin for the rest of the system.

Questions about this item

Will these 2400 MHz DDR4 sticks work alongside the 2400 MHz DDR4 modules I already have in the other two slots?

The kit is validated for ASRock Fatal1ty Z170 and Z270 boards with four DDR4 slots supporting up to 64 GB. Installing two additional 8 GB DIMMs of the same speed and voltage fills the remaining channels without changing the memory controller settings.

How can I confirm the 16 GB kit is running at 2400 MHz with CL17 timings after installation?

Open the BIOS or a system-information tool and verify the memory frequency reads 2400 MHz and the timings show 17-17-17 at 1.2 V.

What does the package contain and is anything else required to use the memory?

The box includes two 8 GB 288-pin DDR4 DIMMs. No extra cables, brackets or software are needed; the modules plug directly into the motherboard slots.
