Kit for ASRock Z270 boards

This 32GB kit contains two 16GB DDR4 modules built for ASRock Z270 Extreme4, Killer SLI/ac, Pro4, SuperCarrier, Taichi, Z270M Extreme4 and Z270M Pro4 motherboards. It runs at 2400 MHz with CL17 timings and 1.2V operation. Builders upgrading compatible Z270 systems receive matched sticks validated for those specific models.

Half the board maximum

The motherboards listed support up to 64GB across four slots, so this 32GB pair leaves two sockets free for later expansion. Dual-rank 2Rx8 organisation and 17-17-17 timing deliver stable throughput at the rated PC4 19200 speed. Buyers who want the full 64GB capacity will need a second identical kit to populate the remaining slots.

Plain modules, direct fit

Unbuffered non-ECC DIMMs without heat spreaders keep the profile low for tight CPU cooler clearances. Standard 288-pin layout drops straight into the four DDR4 slots on the target boards. The kit ships as two sticks backed by the manufacturer lifetime exchange warranty against defects.

Questions about this item

Will this 32 GB kit work with the 16 GB DDR4 sticks already in my Z270 board?

The modules are DDR4 2400 CL17 1.2 V unbuffered non‑ECC; matching speed, voltage and timings gives the best chance of stable operation alongside existing sticks.

How can I confirm the kit runs at DDR4 2400 CL17 after installation?

In the BIOS or a utility like CPU‑Z check that the DRAM frequency reads 2400 MT/s and the timings show 17‑17‑17 at 1.2 V.

What comes in the box and is anything else needed for the Z270 motherboard?

The package contains two 16 GB 288‑pin DIMMs; no extra cables, brackets or software are required for the listed ASRock Z270 boards.
