OC Genie with Super Unlock

Push to overclock in 1 second

MSI’s original invention, a fully automatic, smart overclocking chip.
It will automatically detect the optimal settings for your individual system
Super Unlock= OC Genie + Auto Unlock CPU Ratio
Support Intel Unlocked CPU (Core i7-875K & Core i5-655K)
Advantages

1. 300% higher than Turbo Boost
2. Overclock 4 core B-clock & Ratio by OC Genie
3. Automatically overclock CPU performance to 4GHz

*To enable OC Genie, we suggest you using the new 1.65V XMP memory modules and a high efficiency CPU cooler.
*While you enable OC Genie to detect your system configuration please don’t turn on any parts of V-switch simultaneously. That behavior would offer too much voltage for device and would be possible to cause some damage of device.

DrMOS

1 Phase DrMOS > 4 Phase Traditional MOSFET

3-in-1 server class power component, 400% faster than traditional MOSFET
Offers excellent energy-saving capability and high-computing performance.
Advantages
.
1. High Efficiency: Up to 96%
2. Efficiency Increase: +38.3%
3. Lower Power Loss: -4.01W (64% Max Saving)
