ASRock Z77 OC Formula, the professional OC orientated motherboard, incorporates an exclusive OC Formula Power kit, connector kit and cooling kit to help you achieve the highest overclocking score. As the Excalibur of Arthur, the Z77 OC Formula endows you with great power to break through the barrier and create the new record.


  • newegg Digi Power with 12 + 4 Power Phase Design The OC Formula Power Kit includes Digi Power, 12 + 4 Power Phase Design, Dual-Stack MOSFET (DSM), Multiple Filter Cap (MFC), and Premium Alloy Choke. Compared to analog PWM, digital PWM can optimize the CPU power solution and provide a proper and stable Vcore for the processor. Z77 OC Formula is equipped with CHIL 8328 silicon which features a new digital PWM (Pulse-Width Modulation) design, providing CPU Vcore voltage more efficiently and smoothly. ASRock Z77 OC Formula is designed with a 12 + 4 Power Phase design. It features sturdy components and completely smooth power delivery to the CPU. Plus, it offers unmatched overclocking capability and enhanced performance with the lowest temperature for advanced gamers as well.
  • newegg Premium Alloy Choke & Dual-Stack MOSFET (DSM) & Multiple Filter Cap Compared to iron powder choke, the new Premium Alloy Choke technology on OC Formula Series highlights a special alloy formula which is able to reduce up to 70% core loss. The revolutionary choke construction features a highly-magnetic and heat-resistant design, increasing the board’s lifespan as well. DSM is an innovative new design of MOSFETs. The silicon die area is increased by stacking two dies into a MOSFET. The larger the die area, the lower Rds(on). Compared to traditional discrete MOSFET, DSM can provide larger die area and lower Rds(on), so the power supply for CPU Vcore is more efficient. MFC (Multiple Filter Cap) design includes a combination of highly conductive MLCC, DIP caps and POSCAP. MFC helps the system filter noise from high-freq, mid-freq to low-freq noise, delivering enhanced and higher current to the CPU. With the combined power of three capacitors, MFC allows users to overclock their PC rig to extreme levels without worrying about the hardware components.
  • newegg OC Formula Connector Kit OC Formula Connector Kit includes Hi-Density Power Connector and 15µGold Finger for CPU and memory sockets. Hi-Density Power Connector features a solid square-pin design. ASRock Z77 OC Formula is equipped with two High-Density Power Connectors, one for the CPU Power connector, and one for the 24-pin ATX power connector. The optimized design supplies current to the power more efficiently and achieves better electric conduction. Overall, Hi-Density Power Connector can reduce 23% power loss and decrease system temperature up to 22?. ASRock also has embedded 15µ Gold Finger for both CPU sockets and DRAM slots. Compared to other boards that come with only 3-4µ, ASRock Z77 OC Formula provides 15µgold components within the sockets, delivering triple performance than usual. With the unprecedented 15µ gold-inside design, overclocking the CPU and memory is easier than ever.
  • newegg OC Formula Cooling Kit Twin-Power Cooling combines active air cooling with water cooling. The ultimate heatpipe cooling design maximizes the system’s convection to expel hot air out, providing great air flow and faster heat dissipation. Brilliantly designed to boost performance with the lowest temperature, the OC Formula is built on an 8-layer-PCB design. It comes with 4 sets of 2 ounces copper inner layers, using only carefully selected copper materials for PCB layers, delivering lower temperature and higher energy efficiency for overclocking. GELID Solutions GC-Extreme Thermal Compound is an added bonus included in Z77 OC Formula which allows overclockers to stabilize the CPU’s temperature. Created for extreme users on highest level, the GC-Extreme Thermal Compound achieves the best heat conductivity from your CPU, VGA or even Chipset to your cooler. Not only keeping your rig cool, the GELID GC-Extreme can also make the compound non-freezing even at low temperatures when doing LN2 extreme overclocking.
  • newegg Easy Overclocking Now you’ve got a chance to learn a few tricks from the champion of global OC with NickShih’s OC Profile. It doesn’t matter whether you’re using a K-Series or No-K Series CPU, NickShih’s OC Profile will detect your CPU and offer you different levels of overclocking. Have a taste of Nick’s secret recipe for overclocking this motherboard instantly. ASRock Formula Drive is an all-in-one software to fine-tune different features in an user-friendly interface, which includes Hardware Monitor, FAN-tastic Tuning, Overclocking, OC DNA, IES, XFast RAM and Multi Thermal Sensor. The onboard Rapid OC button allows novice overclockers to manually raise and lower the CPU ratio, BCLK frequency and CPU VCore voltage, while serious OC enthusiasts can use it to get the highest level of overclocking performance from their system and find their CPU’s best margin. Timing Configurator provides subtle DRAM setting for professional tweaking. This app runs under Windows and activate your changes immediately.
  • newegg Comprehensive Monitoring and Control Multi Thermal Sensor provides users the temperature of various parts of the motherboard graphically in UEFI Setup Utility, so that users may precisely keep track and control of the temperature of each parts of the board. FAN-Tastic Tuning offers the flexibility to adjust the fan speed (RPM) relative to the system temperature. Users are able to adjust the setting by clicking the "+/-" and confirm by "APPLY" afterwards. For those who constantly need to remove then reinstall their PCIe cards and fear of causing damage, ASRock has added three PCIe ON/OFF switches to enable or disable the PCIe slots in a flick of your finger. Fine-Tuning V-Controller is a new collection of voltage fine tuning options in UEFI Setup Utility. It provides more than enough voltage configuration options for overclockers who wish to pursuit extremes. V-Probe is a 7-set of detection points laid on this motherboard. It allows overclockers to easily and quickly get the accurate voltage readings via the multitester.
