ASRock Z77 OC Formula Motherboard Review

Motherboards/Intel S1155 by stefan @ 2013-02-04

The Z77 OC Formula is one of the high performance motherboards from ASRock, was built in cooperation with the well-known overclocker Nick Shih and features a 12 + 4 VRM design covered by a massive waterblock/heatsink, an 8-layer PCB, measuring points, plenty of thermal sensors and more. What we also like about this board is the fact that they have removed the legacy components like Floppy/IDE interfaces along with the PCI slots, in order to have a clean motherboard PCB design in the end.

The revolutionary choke construction features a highly-magnetic and heat-resistant design, increasing the board’s lifespan as well.


Dual-Stack MOSFET (DSM)


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.


Digi Power


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.


Multiple Filter Cap (MFC)


The ASRock Z77 OC Formula features a new capacitor design called MFC (Multiple Filter Cap), which 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.


Twin-Power Cooling


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.


8 Layer PCB, 4 x 2oz Copper


Brilliantly designed to boost performance with the lowest temperature, ASRock Z77 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


GELID Solutions GC-Extreme Thermal Compound is an added bonus included in ASRock 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.


Hi-Density Power Connector


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 power connector temperature up to 22?.


15μ Gold Finger


ASRock 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.
