Extreme Engine with ML Cap Design
Say hello to max headroom
Overclocking is all about headroom and for this motherboard has the Extreme Engine—a next-generation dynamic multi-phase power management system equipped with high performance Multilayer type Polymer Capacitors (ML Caps). Extreme Engine ensures a stable power supply during overvoltage by lowering Equivalent Series Resistance (ESR), keeping critical components such as the processor, system memory and the Northbridge reliable. This means you’ll be able to push your spanking new Intel Core i7 CPU to the limit, hitting benchmark scores that others only dream of.

BIOS FlashBack
Two BIOS ROM. Two BIOS settings. Twice the overclocking flexibility.
Overclocker´s prayer to have BIOS flexibility is answered! With the new BIOS Flashback, PC enthusiasts can overclock with even more confidence. BIOS Flashback gives overclockers the ability to save two versions of the BIOS simultaneously. Very much like the "SaveGame" function, one BIOS can be used for the overclocking adventure, while the other BIOS is to be stored with any previous version. BIOS Flashback brings the ultimate convenience to overclockers!

Extreme Tweaker
One stop performance tuning shop
Extreme Tweakers is the one stop shop to fine-tune your system to optimal performance. No matter if you´re looking for frequency adjustment, over-voltage options, or memory timing settings, they´re all here!
