Product Overview

Designed for Overclockers!

Rules are meant to be broken. Limits don't exist. There is no spoon. Only motherboards that are custom made for overclockers.

13 Phase CPU Power Design + 2 Phase Memory Power Design

Features sturdy components and completely smooth power delivery. Offers unmatched overclocking capabilities and enhanced performance with the lowest temperature.

Quad Channel Memory Support: (One DIMM Per Channel)

A special 8-layer layout that allows OC Formula supports Quad-Channel memory. Ideally designed for extreme memory overclocking with huge potential and stability.

Ultra Cool XXL Aluminium Alloy Heatsink & Heatpipe Design

Supports up to 450W CPU with airflow. Extra-large aluminium alloy heatsink along with heatpipe that effectively take away heat from the MOSFET, so that your whole system may perform more stable.

Hyper BCLK Engine III

An additional external base clock generator that supports PCIe frequency overclocking. It provides a wider range of frequencies and more precise clock waveforms, allowing any user to get most from their CPU investment with precise, stable overclocking.

Front USB 3.1 Gen2 Type-C

Front USB 3.1 Gen2 Type-C header delivers up to 10 Gbps data transfer rate and next generation reversible USB design to the front panel of computer case.

OC Formula Kit

OC Formula Power Kit: Digi Power, Dr. MOS.
OC Formula Connector Kit: Hi-Density Power Connector, 15µ Gold Contact.
OC Formula Cooling Kit: 8 Layer PCB, 2oz Copper PCB, Heat Pipe Design.

Retry/Reset/BFG Button

Retry Button: Restart system immediately with cold boot when the system needs to be forced shutdown or retry the same BIOS setting by training again.
Reset Button: Quickly reset the system without cold boot.
BFG Button: Enforce system to boot as default but keep BIOS setting if pressing this button during power cycle.

PCIe On/Off

Enable or disable the PCIe slots with a flick of your finger.

Rapid OC

To manually raise or lower the system's CPU ratio, BCLK frequency or CPU Vcore voltage.

LN2 Mode

Use the onboard switch to activate LN2 Mode and disable the CPU’s thermal protection.

Nick Shih’s OC Profile

It’s your chance to learn a few tricks from the champion. The legendary overclocker Nick Shih has added a few presets for different levels of overclocking.

Supports 4-Way SLI / CrossFireX VGA Cards

This flagship motherboard is able to support 4-Way SLI or 4-Way CrossFireX effortlessly. Not only support gaming graphics card, it is also fully compatible with NVIDIA® Quadro® & AMD FirePro professional desktop workstation graphics solutions. *Please refer to NVIDIA® & AMD website for the Multi-GPU supported graphics card list.


Build your own colourful lighting system! RGB LED and header allows users to connect LED strips and create their unique PC style easily. The ASRock RGB LED utility can be downloaded directly or from an all-in-one utility ASRock Live Update & APP Shop!

Dual Ultra M.2 For SSD

Two of the world’s fastest PCIe Gen3 x4 Ultra M.2 slots that deliver up to 32Gb/s transfer speed, it also supports SATA3 6Gb/s M.2 modules.

Dual Intel® LAN

Users are able to connect two LAN cables to this motherboard's rear I/O. Dual LAN with Teaming function enabled on this motherboard allows two single connections to act as one single connection for twice the transmission bandwidth, making data transmission more effective. *Teaming is not supported with Windows® 10.

XXL Aluminium Alloy Heatsink

Extra-large aluminium alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable.

Premium 60A Power Choke

Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard.


Dr. MOS design features the latest SPS (Smart Power Stage) technology. It’s optimised for monitoring current and temperature of each phase, thus delivering smoother and neater power to the CPU with enhanced performance and OC capability.

Nichicon 12K Black Caps

Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20% longer lifespans and provide more stability and reliability.

Matte Black PCB

A new mysterious matte black and copper colour scheme to match the prestigious components on ASRock's high-end motherboards.

High Density Glass Fabric PCB

High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

Formula Drive

Specifically designed for perfectionist that wish to fine tune every tiny little aspect of their personal computer.

Live Update & APP Shop
