OC Genie

In the past, users needed to adjust settings for CPU and Memory in BIOS menu to overclock. The relation between these ratios and clocks speeds are extremely complicated, taking up to 30 minutes to find the right settings for an optimized PC.  OC Genie simplifies it all into one button press. Where high-end CPUs are usually priced around 1000 USD, OC Genie allows you to take a 200 USD CPU (1/5 the price) to reach the same performance. Your C/P ratio rises up 500% immediately for the ultimate value.
   
Features
- The world's first Auto Overclocking Processor
- Upgrade full system performance in 1 sec
- Auto detect overclocking settings of CPU and Memory
- Compatible with Intel/AMD platform

DrMOS

In order to provide customers stable and high quality products, starting from P45 series motherboards, MSI is leading the industry to introduce the world's most advanced power supply component, DrMOS (Driver-MOSFET), which integrates Driver IC, Top MOSFET and Bottom MOSFET into one chip. Except for its outstanding performance in power saving, DrMOS possesses switch frequency which is 400% faster than traditional MOSFET and has great improvement in stabilizing power supply and voltage control. Even under heavy loading and overclocking conditions, DrMOS can still provide the most stable and efficient power supply and quality.

APS (Active Phase Switching)

Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s motherboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage.
