Six 975X Enthusiast Motherboards for Today and Tomorrow

Motherboard Components

Asus uses Intel's 6702PHX workstation/server Southbridge...

...that supports two PCI-X slots.

This jumper defines the PCI-X bus speed (Auto/100/133 MHz). It reaches 1.06 GB/s at the maximum speed using its 64-bit bus width, but the bandwidth is shared by the two slots.

A Marvell 88SE6141 PCI Express SATA controller offers four additional ports for hard drives.

The dual Gigabit Ethernet controller is attached via PCI-X.

Asus provides an 8-phase voltage regulator for maximum system stability.
