Verdict

The ASRock X370 Killer SLI/ac is an ATX motherboard for AMD's AM4 socket, featuring the X370 chipset and a robust 12-phase power design with 45A power chokes and Nichicon 12K black capacitors for enhanced stability. Key specifications include support for DDR4 memory up to 2933+ (OC), dual M.2 slots (one Ultra M.2 at 32Gb/s and one at 10Gb/s), and integrated Intel 802.11ac Wi-Fi. Main pros include its competitive pricing, support for both NVIDIA Quad SLI and AMD Quad CrossFireX, and premium 'Super Alloy' build quality with RGB lighting. However, notable cons include the lack of a POST code debugger and some reported difficulty achieving high memory speeds like 3200MHz.
