Intel® Smart Response Technology
Faster Access, Bigger Storage
Intel® Smart Response Technology boosts overall system performance. It uses an installed fast SSD (min 18.6GB available) as a cache for frequently accessed operations, speeding up hard drive/main memory interaction. Key benefits are expedited hard drive speeds, reduced load and wait times and maximized storage utilization. Power consumption also goes down by reducing unnecessary hard drive spin, an important part of Green ASUS eco-friendly computing.

Why choose when you can have both? SLI or CrossFireX? Fret no longer because with the ROG Maximus IV Extreme-Z, you´ll be able to run both multi-GPU setups. The board features SLI/CrossFireX on Demand technology, supporting SLI or CrossFireX configuration. Whichever path you take, you can be assured of jaw-dropping graphics at a level previously unseen.

ROG Connect
Plug and Overclock - Tweak it the hardcore way! Monitor the status of your desktop PC and tweak its parameters in real-time via a notebook—just like a race car engineer—with ROG Connect. ROG Connect links your main system to a notebook through a USB cable, allowing you to view real-time POST code and hardware status readouts on your notebook, as well as make on-the-fly parameter adjustments at a purely hardware level.

ROG iDirect
Tune your PC from your iPhone or iPad now! Still overclocking your PC the old-fashioned way? Let ROG iDirect bring you a whole new tweaking experience right on your iPhone or iPad! Thanks to the Bluetooth card that comes with select ASUS ROG motherboards, you can monitor your PC and tweak parameters such as voltages and frequencies in real time wirelessly from your iPhone or iPad!

RC Bluetooth
Smashes through all the barriers of conventional overclocking ! Still overclocking in old-fashioned way? Let RC Bluetooth bring you the whole new idea of how to do! Just simply push the button from the Back I/O on the RC Bluetooth card, overclockers can real-time monitor the desktop PC system status & tweak its parameters - such as voltages and frequency on the fly. When users want to use ordinary bluetooth functions, just simply push the button once again & enjoy all the wireless convenience brought from RC Bluetooth.

USB BIOS Flashback
Refresh the BIOS can never be that easy USB BIOS Flashback must be the most convenient way to flash BIOS ever! It allows overclockers to try their BIOS with the simplist way one can imagine. No need to enter the BIOS or the operating system, just plug the thumb drive into the ROG Connect port & push the ROG Connect button for 2 seconds, BIOS would be automatically flashed under standby power. It's no doubt that USB BIOS Flashback gives overclockers the ultimate convenience!

Extreme Engine Digi+
Powerful combination of analog and digital design elements Extreme Engine Digi+ equipped with high performance digital VRM design can easily achieve the ultimate performance with adjustable CPU PWM frequency. It expedites heat dissipation and achieves better electric conduction keeping critical components reliable. Now you'll be able to push your spanking new Intel CPU to the limit, hitting benchmark scores that others only dream of. Extreme Engine Digi+ balances the need for voltage and the desire for rock solid performance to bring the ultimate user experience.

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!

Mem TweakIt
Dynamic timing adjustments, DRAM efficiency gauge When changing DRAM settings in BIOS, it always takes time for the system to reboot. Worry no more! With Mem TweakIt, you can do DRAM tuning in real-time, view your DRAM efficiency score, and upload and share your ranking online.
