16GB DDR4 2400MHz DIMM for ASRock Z170 and X99

This 16GB DDR4 2400MHz CL17 DIMM is built for owners of ASRock Z170 Extreme or X99M Extreme4 boards who need a single 16GB module to reach the platform’s 64GB maximum across four slots. The unbuffered non-ECC stick runs at 1.2V with 17-17-17 timing.

Who this suits and who should look elsewhere

The module suits builders upgrading a compatible ASRock Z170 or X99M Extreme4 system that accepts 288-pin DDR4 DIMMs without ECC or registered buffers. It does not suit buyers who need ECC error correction, registered signal buffering, a heat spreader, or speeds above 2400MHz.

The specification that decides fit

The decisive specification is the validated compatibility list: ASRock Z170 Extreme3, Extreme4, Extreme4+, Extreme6, Extreme6+, Extreme7+ and X99M Extreme4. If your motherboard is not on this list, the module is not guaranteed to work.

Questions about this item

Does the C113 kit include anything besides the single 16 GB DDR4 stick?

No. The package content lists only one 16 GB 288-pin DDR4 DIMM; no heat spreader, cables or tools are supplied.

The board supports up to 64 GB across four slots — should I buy one 16 GB module or fill all slots at once?

One 16 GB module leaves three slots free for later expansion; populating all four slots immediately is only necessary if you need the full 64 GB today.

My Z170 Extreme4 runs at 2400 MHz CL17 — will this stick actually operate at that speed and latency?

Yes. The module is rated DDR4 2400 (PC4 19200) with 17-17-17 timings at 1.2 V, matching the board's supported specification.
