ASRock Fatal1ty AB350 Gaming K4 AM4 ATX motherboard

This ASRock Fatal1ty AB350 Gaming K4 board uses the AMD Promontory B350 chipset on an ATX form factor. It fits AM4 socket processors including Ryzen Summit Ridge CPUs and Bristol Ridge A-Series APUs. Four 288-pin DDR4 slots support up to 64 GB in dual-channel mode.

Suits Ryzen builders needing dual x16 slots

The board suits builders who want two PCI Express 3.0 x16 slots and an Ultra M.2 socket running at Gen3 x4 with a Ryzen CPU. It also provides four SATA3 6.0 Gb/s ports from the chipset plus two more via ASMedia ASM1061. Users needing integrated Wi-Fi or more than four memory slots should look elsewhere.

Ultra M.2 socket M2_1 runs at Gen3 x4

The single Ultra M.2 socket (M2_1) accepts M Key 2242, 2260 or 2280 modules and delivers PCI Express 3.0 x4 bandwidth (32 Gb/s) when paired with a Ryzen processor. With an A-Series APU the same slot operates at x2 (16 Gb/s). This lane allocation is the key spec for storage performance.

Questions about this item

Will my case fit this ATX motherboard and its CPU cooler clearance?

The board uses the standard ATX form factor, so any case that accepts ATX will fit. Check your case specifications for maximum CPU cooler height to ensure the cooler you choose clears the socket area.

Which M.2 slot gives the fastest speed with a Ryzen CPU?

The Ultra M.2 socket (M2_1) runs at Gen3 x4 (32Gb/s) when a Ryzen series CPU is installed. The second M.2 slot (M2_2) operates at Gen3 x2 and shares lanes with SATA3_3, so using it disables that SATA port.

Can I run four sticks of DDR4 at 3200 MHz with a Ryzen processor?

The board has four DDR4 slots supporting up to 64GB in dual channel. Ryzen CPUs list DDR4 3200+(OC) as supported, but stability with four populated slots at that frequency depends on the memory kit and CPU memory controller; consult the ASRock memory support list for validated kits.
