1-2 Chapter 1: Product Introduction
1.3 Special features
1.3.1 ROG intelligent Performance & Overclocking features
Crosslinx
Crosslinx is a unique technology utilizing a dedicated special graphics controller to
optimize PCIe allocation with x16, x8, x8 lanes. Such architecture eliminates the x4
bottleneck found on competing x16, x16, x4 solutions. Hence, the Crosslinx is able
to provide faster graphics performance.
Fusion Block System
The Fusion Block System is a more efcient thermal solution compared to
competing followers with complicated looks. It is a hybrid thermal design that
combines the ROG’s renowned heatpipe design with the additional ability to
connect to a water cooling system. By taking the entire integrated solution into
design considerations, the user can enjoy exceptional thermal improvement to
Northbridge, Southbridge, Crosslinx, and even VRM with a single connection. The
Fusion Block System is the most versatile, efcient, and advanced thermal system
there is on a motherboard.
Component Overheat Protection -EX (COP EX)
The COP EX allows overclockers to increase chipset voltages without the worries
of overheating. It can also be used to monitor and save an overheating GPU.
The COP EX allows more freedom and less constraint for maximum performance
achievement.
Frequency LED
Worried that no one knows when you’ve overclocked your system to the max? Let
the motherboard do the talking! The onboard Frequency LED highlights when your
system is under extreme overclocking or normal states � allowing you to show off
your O.C. skills.
Voltiminder LED
In the persuit of extreme performance, overvoltage adjustment is critical but risky.
Acting as the “red zone” of a tachometer, the Voltiminder LED displays the voltage
status for CPU, NB, SB, and Memory in a intuitive color-coded fashion. The
Voltiminder LED allows quick voltage monitoring for overclockers. See pages 2-1
to 2-3 for details.

ASUS Maximus Extreme 1-3
CPU Level Up
Enjoy up to 40% more performance! Overclock immediately with OC prole
presets. Much more than simple frequency settings, this prole gives gamers
comprehensive and detailed tuning to frequencies, voltagies, and even timings to
create a real professional level of overclocking conguration. See pages 4-17 and
5-33 for details.
2-Phase DDR3
With the embedded 2-Phase DDR3, this motherboard allows users to reach higher
memory frequencies and enjoy better performance. Compared with only one phase
solutions, this motherboard ensures longer power component lifespans and higher
overclockability due to cooler temperatures and better efciency.
3rd Generation 8 Phase Power Design
Longer Life & Higher Efciency!
With power efciency so important to operating temperatures, ASUS' 3rd
generation 8-phase VRM design leads the industry with its 95% power efciency.
High quality power components such as low RDS (on) MOSFETs for minimum
switching loss & lower temperatures, Ferrite core chokes with lower hysteresis
loss, and high quality Japanese-made conductive polymer capacitors all add up
to ensure longer component life and lower power loss - creating more energy
efciency.
Loadline Calibration
The Loadline calibration ensures stable and optimal CPU voltage when heavy
loading.
Extreme Tweaker
This feature allows you to ne tune the CPU/memory voltage and gradually
increase the memory Front Side Bus (FSB) and PCI Express frequency at 1MHz
increment to achieve maximum system performance.
AI Booster
The ASUS AI Booster allows you to overclock the CPU speed in Windows
environment without the hassle of booting the BIOS.

1-4 Chapter 1: Product Introduction
ASUS O.C. Prole
The motherboard features the ASUS O.C. Prole that allows users to conveniently
store or load multiple BIOS settings. The BIOS settings can be stored in the
CMOS or a separate le, giving users freedom to share and distribute their favorite
settings. See page 4-40 for details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.
1.3.2 ROG unique features
Supreme FX II features
Supreme FX II extends all the features of the 1st generation and places a shielding
to enhancethe sound quality. It also lights up the model name with stylish LEDs.
Noise Filter
This feature detects repetitive and stationary noises (non-voice signals) like
computer fans, air conditioners, and other background noises then eliminates
it in the incoming audio stream while recording. See page 5-15 and 5-20 for
details.
LCD Poster
The LCD Poster uses an external panel to smartly display the error message of the
physical system during the Power-On Self Test (POST) to inform you the boot error
instead of the “code name.”
Onboard Switches
A power-on button, a reset button, and a clear CMOS button are onboard to
provide overclockers and gamers the convenience of ne-tuning performance
when working on a bare (open-case) system. Press the power-on button to wake
up the system, the reset button to reboot, and the clear CMOS button to clear
setup information when the system hangs due to overclocking. See page 2-40 for
details.
