Verdict

The ASRock Z170 OC Formula is an enthusiast-grade ATX motherboard designed for extreme overclocking on the Intel LGA 1151 socket, supporting 6th and 7th Gen Core processors. It features a robust 18-phase power design, an 8-layer PCB, and support for DDR4 memory speeds exceeding 4500MHz (OC). Key characteristics include triple Ultra M.2 slots (32Gb/s) with RAID support, four PCIe 3.0 x16 slots enabling 4-Way CrossFireX or 2-Way SLI, and dedicated onboard buttons for on-the-fly frequency and voltage adjustments. Its main pros are world-class overclocking potential, a highly detailed UEFI BIOS with Nick Shih profiles, and excellent VRM cooling efficiency. Notable cons include the lack of built-in Wi-Fi and limited 2-Way support for NVIDIA SLI due to PCIe lane configurations.

What customers dislike about ASRock Z170 OC Formula?

  • Premium pricing compared to mainstream Z170 motherboards
  • Lacks integrated Wi-Fi and Bluetooth modules, which are often expected at this price point
  • Using all three M.2 slots disables all Intel chipset-based SATA ports due to shared bandwidth
  • NVIDIA SLI support is limited to 2-way configurations (does not support 3-way or 4-way SLI)
  • Extra non-overclocking controllers (like additional SATA) can inflate the cost for hardcore competitive overclockers
  • The Micro-ATX version (Z170M) only features two RAM slots, limiting future memory expansion
