NVIDIA Quad SLI DIY interviewCitace:
This driver is a Beta driver that enables Quad NVIDIA SLI technology, allowing you to put two GeForce 7950 GX2 graphics cards in a single system with an NVIDIA nForce SLI motherboard. This driver is strictly for end user Beta testing with two GeForce 7950 GX2 graphics cards only and is not intended for production.
If you own, or are planning to buy, two GeForce 7950 GX2 graphics cards to build your own Quad NVIDIA SLI PC, we encourage you to download the beta drivers here and try them out on your NVIDIA SLI PC.
2. We know that motherboard compatibility issues in the past have forced NVIDIA to make Quad SLI only supported in the OEM realm. How active is NVIDIA when it comes to working with motherboard builders to make sure that the GeForce 7950 GX2 Quad SLI will work on past, present, and future motherboards? And what DIY problems did you have to solve in regards to Quad SLI?

Although the GeForce 7950 GX2 is fully compliant with the PCI-Express specification, it was the first mass-produced graphics card design to use a PCI-E switch, and frankly it was unlike anything motherboard builders had seen before. NVIDIA has shared detailed technical information with both motherboard builders and BIOS suppliers (such as Phoenix and AMI) to ensure current and future BIOS revisions are compatible with 7950 GX2 products. We’ve also tested dozens of the most popular motherboards, contacted the manufacturer if any problems were found, and published a list of approved motherboards at www.nvidia.com/gx2. The list gets longer every week, and we’re finding that more and more boards pass on the first attempt without BIOS changes. However, there are still some incompatible motherboards out there, and we recommend you check with your motherboard manufacturer or check NVIDIA’s list of approved boards before purchasing a 7950 GX2.
