Dual PCI-E Graphics Performance
The Intel 975X chipset supports a maximum 8 GB dual-channel DDR2 667/533 architecture, 1066/800 FSB, PCI Express x16 graphics and dual-core CPU. With the 5 x Serial ATA ports routed through the SATA 3 Gb/s RAID controller integrated into the ICH7R Southbridge, the Intel 975X satisfies the raw bandwidth needs of gamers when overclocking both the CPU and memory. The dual PCI-E graphics slots support two 8-lane PCI Express links for fabulous graphics performance for next generation GPUs and games as well as video rendering and other memory intensive applications. With an increasing number PC game developers taking advantage of dual GPU performance, the 975X7AA-8EK7AA is ready for tomorrow’s action.

The “FOX ONE” Advantage
The cutting edge “FOX ONE” central control system is designed exclusively for FOXCONN motherboards with Intel chipsets. It enables the automatic monitoring of a PC's system status, including system frequencies, voltages and temperatures, as well the automatic and intelligent adjustment of major system components. It also gives users the ability to make extensive manual adjustments. FOX ONE Technology enables users to choose between 4 modes: Auto, Power Gaming, Data Mining and Energy Saving. FOX ONE makes it easy for users to tailor their systems to match performance needs, without the risk of damaging the CPU or other components.

The 975X7AA-8EK7AA has a Realtek ALC882H onboard audio codec for HDA and 8-channel (7.1 surround) sound and audio. The board supports eight channel analog outputs along with two digital outputs through optical and RCA S/PDIF connectors. The board supports 8 x USB 2.0 ports. One really useful feature is a rear SATA II external connector that easily extends serial ATA device support without opening the chassis. Faster than USB, it is perfect for an extra SATA HDD or Optical device. The motherboard supports 64-bit and Hyper-Threading technology for the newest Intel processors and software applications. A Dual Marvell 8055 Gigabit (10/100/1000) Ethernet (PCIe) controller provides high performance LAN connectivity. Support for RAID 0, RAID 1, RAID 10, RAID 5 disk management is available as is the new RAIDm1 (Reliable Access In a Disk by mirror1) function that enables RAID 1 functionality in one hard disk, saving the cost of one drive.

The board includes seven super functions that allow users to customize, modify, personalize and backup their motherboard settings. A BIOS backup function is provided provide in case of BIOS boot failure or virus attack.
