CrossFire Chipsets

Below you can find a list with all chipsets that support CrossFire. Under “PCI Express Mode” we listed what is the real transfer rate of the x16 PCI Express slots when CrossFire mode is enabled. Keep in mind that when CrossFire mode is disabled and you have only one video card installed the main PCI Express x16 slot will always work at x16.

ChipsetPCI Express Mode
AMD 790FX
Two PCI Express 2.0 x16 with two video cards
One PCI Express 2.0 x16 and two x8 with three video cards
Four PCI Express 2.0 x8 with four video cards
Intel X38Two PCI Express 2.0 x 16, One PCI Express 1.0 x4 *
AMD 790XTwo PCI Express 2.0 x16
AMD 580X (ATI CrossFireXpress 3200)Two PCI Express 1.0 x16
AMD 570XOne PCI Express 1.0 x16, One PCI Express 1.0 x8
Intel 975XTwo PCI Express 1.0 x8, One PCI Express 1.0 x4 *
AMD 480X (ATI CrossFireXpress 1600)
ATI Radeon Xpress 200 “CrossFire Edition”
Two PCI Express 1.0 x8
Intel P35 **
Intel P965 **
Intel 945P **
One PCI Express 1.0 x16, One PCI Express 1.0 x4
AMD 780G (Hybrid CrossFireX only)One PCI Express 2.0 x16

* Not all motherboards based on Intel X38 and Intel 975X chipsets have three x16 slots.

** Not all motherboards based on these chipsets have two x16 slots, so CrossFire is only supported on models that carry two x16 PCI Express slots.
