ASRock Z270 32 GB kit

This 32 GB kit contains four 8 GB DDR4 modules validated for ASRock Z270 Extreme4, Killer SLI/ac, Pro4, SuperCarrier, Taichi, Z270M Extreme4 and Z270M Pro4 motherboards. The unbuffered non-ECC DIMMs run at 2400 MHz with CL17 timings at 1.2 V. Builders upgrading these specific boards can install the full kit without manual configuration.

288-pin DIMM layout

Each stick uses a standard 288-pin DDR4 edge connector and carries 2Rx8 major-brand chips without a heat spreader. The low-profile design fits beneath most CPU coolers and leaves all four memory slots populated on the target boards. Daily operation stays within the board’s native 1.2 V specification.

DDR4 2400 ceiling

The platform caps memory speed at 2400 MHz, so faster DDR4 modules will downclock to this rate. Maximum supported capacity is 64 GB across four sockets, leaving no room for additional sticks beyond this kit. Buyers needing more than 64 GB or speeds above 2400 MHz must choose a different platform.

Questions about this item

What DDR4 speed does this kit run at and what bandwidth does that cap at?

The kit is rated DDR4 2400, which corresponds to PC4 19200 bandwidth in practice.

What physical slot count and pin layout do these modules need on the motherboard?

Four 288-pin DDR4 DIMM slots are required, matching the board's four-socket layout.

How do I install the four sticks correctly and which mistake should I avoid?

Populate all four slots with the 8 GB modules, ensuring each clicks fully into its 288-pin socket; the common error is leaving a stick partially seated.
