AnandTech: CES 2006 - Day 2: Blu-ray/HD-DVD, PureVideo H.264, Viiv, Centrino Duo and a lot more: "Up Close and Personal with NVIDIA's Quad-SLI
Yesterday we reported on Dell's Inspiron XPS 600 Renegade system that will be shipping with the world's first NVIDIA Quad-SLI setup. Unfortunately the system we showed you pictures of did not actually have the Quad-SLI cards installed, but today at NVIDIA's booth we were able to not only take some pictures of the actual setup but get a better understanding of how it works.
NVIDIA's Quad-SLI works on any nForce4 SLI motherboard with two PCIe x16 slots, in the case of Dell's XPS 600 Renegade the chipset of choice is a nForce4 SLI x16 Intel Edition. There is no technical reason the setup shouldn't work on an AMD nForce4 SLI x16 motherboard."
