Alienware?s patent-pending custom X2 motherboard enables dual high-performance graphics cards. To Alienware?s knowledge, no other motherboard currently supports dual PCI-Express graphics slots. The X2 also utilizes all available PCI-Express lanes provided by the Tumwater chipset, supports DDR2-400 memory and includes 6 ports for high-performance SATA RAID 0, 1, and 0+1 configurations. The X2 includes SATA on a 66MHz PCI-X bus, Gigabit Ethernet, and 5.1 Dolby Digital audio.
The X2 motherboard is dual-CPU, which will ultimately increase CPU processing power.
Due to the power requirements of a dual graphics card system, ALX systems featuring the Video Array will include a custom power supply rated at 700+ Watts.
