Socket and chipset support CPUs targeted at the high-end desktop (HEDT) and enthusiast segments of the Intel product lineup: Core i7-branded and Xeon-branded processors from the Sandy Bridge and Ivy Bridge CPU architectures.
The supported CPUs feature quad channel memory controllers, and a certain amount of PCIe lanes, the chipset features additional PCIe lanes; it is designed to connect an Intel processor through a DMI 2.0 interface to peripheral devices.

Partial support for Windows XPEdit
The X79 chipset does not support installing Windows XP in AHCI mode for Intel's Serial ATA controllers as Intel won't release AHCI drivers for 32-bit Windows XP. Windows XP can be installed in IDE mode but without SATA features enabled. For users that dual boot Windows XP with another operating system installed in AHCI mode, this means changing to IDE mode every time to boot into Windows XP and changing back to SATA to boot the other OS, or installing the other OS which supports AHCI also in IDE mode to prevent switching the setting in the BIOS each time. This restriction applies only to 32-bit Windows XP; 64-bit Windows XP is supported by Intel drivers.
For motherboards with X79 chipset but with third party SATA disk controllers, 32-bit Windows XP AHCI drivers may still be supported by the disk controller vendor (non-Intel).
