What customers don't like about ASRock X370 Killer SLI/ac

  • Lack of an onboard POST code debugger or diagnostic LEDs
  • Early BIOS versions had issues with high-speed RAM compatibility
  • The green PCB on the Wi-Fi module clashes with the board's monochrome design
  • Some users reported the Load-Line Calibration (LLC) settings were removed or inconsistent in later BIOS updates
  • Awkward placement of some headers, such as the rear exhaust fan or AMD Wraith LED header
  • Flimsy I/O shield compared to higher-end models

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.
