Finally, there’s the new licensed native SLI setup on X58 boards, which allows standard two-way SLI via two PCI-E slots with either 16 or eight lanes.
The other catch is that motherboard manufacturers have to send their X58 boards to go through Nvidia’s SLI Certification Labs in order to receive the ‘cookie’ that will then be embedded into the BIOS to enable full SLI support. According to Berraondo, SLI support is only ‘turned on only when our drivers determine that the motherboard has passed a special check that makes sure the key and chipset ID are a match and are in fact, certified to run SLI.’
