Does this board support 8th or 9th gen Intel CPUs?

No. The Z270 chipset and this LGA 1151 socket support 6th and 7th gen Intel Core, Pentium, and Celeron processors. 8th and 9th gen chips need a 300-series board despite the same socket shape.

Can I overclock on this motherboard?

Yes. Z270 supports CPU and memory overclocking, but only with unlocked 'K' processors such as the i5-7600K or i7-7700K. Locked chips run at stock speeds.

How many M.2 drives can I install?

Two. The board has dual M.2 slots, and one of them supports NVMe drives at PCIe Gen3 x4 speed. Check the manual for which SATA ports get disabled when both are used.

Yes. The 'ac' in the name means onboard 802.11ac Wi-Fi, so no separate card is needed. It also has the Killer E2500 wired network port.

What memory does it take?

Four DDR4 DIMM slots, up to 64GB total, rated at 2400 MHz. Higher-speed kits can work but may need manual settings in the BIOS.

Is it worth buying in 2024?

Only if you already own a 6th or 7th gen Intel CPU and need a replacement board cheaply. For a new build, a modern platform gives you a current socket, USB-C, and a warranty.

Our take on the ASRock Z270 KILLER SLI/AC ATX Motherboard

The ASRock Z270 Killer SLI/ac is an ATX motherboard for Intel's 6th and 7th generation Core processors on the LGA 1151 socket, built around the Z270 chipset with support for overclocking and dual graphics cards. It pairs four DDR4 slots (up to 64GB) with dual M.2 slots, onboard 802.11ac Wi-Fi, and a Killer E2500 gaming network chip. It is a 2017-era board, so it suits budget builders reusing an older CPU rather than anyone starting a new build. No current store price was provided, so check its price history before buying.
