Together, these perfect your BIOS experience.



Performance Optimization

USB 3.0 Boost (UASP Support)

170% faster transfer speeds than traditional USB 3.0

ASUS USB 3.0 Boost technology supports UASP (USB Attached SCSI Protocol) in Windows 8. With USB 3.0 Boost technology, a USB device's transmission speed is significantly increased up to 170%, adding to already fast USB 3.0 performance. ASUS software automatically accelerates data rates for compatible USB 3.0 peripherals without any user interaction.

World’s 1st USB 3.0 UASP support – instantly 170% faster.
Complete USB 3.0 solution – performance boost under Turbo Mode or UASP Mode for most USB devices.
Simple plug and boost – auto detection design ensures best performance.


Q-Slot

Effortless PCI Express component removal

Press the Q-Slot clip lightly, and graphics cards just pop out. The large winged clip is easy to reach so you don’t have to struggle with installing or removing even the biggest graphics cards.

ASUS Boot Setting

Multiple startup options

Thanks to ASUS Windows 8 hardware optimization, ASUS Boot Setting provides better flexibility in customizing your PC’s startup process. You can shorten system boot-up time to 2-seconds* for a smoother user experience under Windows 8, and even previous versions of Windows. Also, you can enter the BIOS directly with one click through a user-friendly interface, and quickly select your preferred system boot up method: either get to the OS in seconds or opt for regular boot up. Whatever your choice, settings are saved and persistent, with no need to choose every time you power on.
