Core™ i7 Processor Family is one of the most powerful 

and energy efficient CPUs in the world.

The Intel

 X79 Express Chipset is the latest single-chipset design that supports the new 

socket 2011 2nd Generation Intel

Intel

 Core™ i7 Processor Family. It improves performance by

Core™ i7 Processor Family. It improves performance by 

utilizing serial point-to-point links, allowing for increased bandwidth and stability. Additionally, 

the X79 comes with 2 SATA 6Gb/s and 4 SATA 3Gb/s ports for faster data retrieval, doubling 

the bandwidth of current bus systems.

Both SLI and CrossfireX architectures work flawlessly on new ASUS X79 boards, with PCI 

Express slots designed to accommodate the power of up to three current graphics cards. 

Whether for professional graphics work, heavy duty multimedia or dedicated gaming, more 

than ample graphics power can be applied whenever needed.

The motherboard supports DDR3 memory that features data transfer rates of 2400(O.

C.)/2133(O.C.)/1866/1600/1333/1066 MHz to meet the higher bandwidth requirements of 

the latest operation system, 3D graphics, multimedia, and Internet applications. The quad-

channel DDR3 architecture quadruple the bandwidth of your system memory to boost system 

performance.

ASUS facilitates strategic USB 3.0 accessibility for both the front and rear panel – 4 USB 3.0 

ports in total. Experience the latest plug & play connectivity at speeds up to 10 times faster 

than USB 2.0. The P9X79 LE affords greater convenience to high speed connectivity.

The latest PCI Express bus standard delivers improved encoding for twice the performance 

of current PCIe 2.0. Total bandwidth for a x16 link reaches a maximum of 32GB/s, double 

the 16GB/s of PCIe 2.0 (in x16 mode). PCIe 3.0 provides users unprecedented data speeds, 

combined with the convenicnce and seamless transition offered by complete backward 

compatibility with PCIe 1.0 and PCIe 2.0 devices. It is a must-have feature PC users aiming 

to improve and optimize graphics performance, as well as have the latest, most future-proof 

technology.
