Asus MAXIMUS III Extreme 16GB DDR3 INTEL Motherboard

Supports Intel® Processors in the LGA1156 Package
This motherboard supports the latest Intel® Lynnfield processors in LGA1156 package, which as memory and PCI Express controller integrated to support 2-channel (4 DIMMs) DDR3 memory and 16 PCI Express 2.0 lanes, providing great graphics performance. Intel® Lynnfield processor is one of the most powerful and energy efficient CPU in the world

Intel® P55 Chipset
The Intel® P55 Express Chipset is the latest one-chipset design to support the latest 1156 socket Intel® Lynnfield processors. Intel P55 provides improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability

Double Speed; Double Bandwidth
This motherboard supports the latest PCIe 2.0 devices for double speed and bandwidth which enhances system performance.

Dual-Channel, DDR3 2200(O.C.) MHz
The motherboard supports DDR3 memory that features data transfer rates of 2200(O.C.) / 2133(O.C.) / 2000(O.C.) / 1800(O.C.) / 1600(O.C.) / 1333 / 1066 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3 architecture double the bandwidth of your system memory to boost system performance.

Overwhelm your acknowledgement with wireless overclocking experience
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.

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.

Memory is A-OK
Memory compatibility is among the top concerns when it comes to computer upgrades. Worry no more, MemOK! is the fastest memory booting solution today. This remarkable memory rescue tool requires nothing but a push of a button to patch memory issues and get your system up and running in no time. The technology is able to determine failsafe settings that can dramatically improve system booting success.

Intelligent multiple control at hand
The iROG is a special IC which enables several ROG highlitghted functions that gives users full disposal of the motherboard at any stage! This design allows advanced user control and management to be processed purely at a hardware level. iROG greatly increases fun during overclocking for PC enthusiasts and it offers system maintainence and management with more control and efficiency.

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! By pushing BIOS button, overclockers can easily choose which BIOS ROM they want to save & boot from.

Get all hands-on with hardware-based overclocking
ProbeIt takes the guesswork out of locating the motherboard´s measurement points, identifying them clearly in the form of 5 sets of detection points so you´ll know exactly where to get quick yet accurate readings using a multitester.

A Simple click for instant upgrade
Ever wish that you could have a more expansive CPU? Upgrade your CPU at no additional cost with ROG´s CPU Level Up! Simply pick the processor you wanted to OC to, and the motherboard will do the rest! See the new CPU speed and enjoy that performance instantly. Overclocking is never as easy as this.

Friendly reminder on Voltage Settings
In the pursuit 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, PCH, and Memory in a intuitive color-coded fashion. The voltiminder LED allows quick voltage monitoring for overclockers.

Optimal power boost for extreme CPU overclocking
Maintaining ample voltage support for the CPU is critical during overclocking. The Loadline Calibration ensures stable and optimal CPU voltage under heavy loading. It helps overclockers enjoy the motherboard´s ultimate OC capabilities and benchmark scores.

Make connections quick and accurate
The Q-Connector allows you to connect or disconnect chassis front panel cables in one easy step with one complete module. This unique adapter eliminates the trouble of plugging in one cable at a time, making connection quick and accurate.

10X Faster Date Rates
Experience ultra-fast data transfers at 4.8Gbps with USB 3.0—the latest connectivity standard. Built to connect easily with next generation components and peripherals, USB 3.0 transfers data 10X faster and is also backward compatible with USB 2.0 components.

Conveniently store or load multiple BIOS settings
share and distribute favorite overclocking settings The motherboard features the ASUS O.C. Profile that allows users to conveniently store or load multiple BIOS settings. The BIOS settings can be stored in the CMOS or a separate file, giving users freedom to share and distribute their favorite overclocking settings.
