All OEM X58 motherboard manufacturers will have to submit their boards for certification by NVIDIA. NVIDIA will also be charging an undisclosed certification fee. If the board passes certification, NVIDIA issues a BIOS key enabling SLI. The NVIDIA SLI drivers check for the presence of this key. NVIDIA will continue to design chipsets for Penryn based platforms, but it will not be making any QPI enabled chipsets for Nehalem. Thus, with Nehalem, the only way to get SLI support with an LGA-1366 MB would be to use an Intel chipset. NVIDIA will be making LGA-1160 based Nehalem motherboards (dual-channel DDR3) for the low end and mainstream markets, but that platform isn't expected to debut until late 2009.
