If you want to combine a pair of GeForce graphics cards with a new Core i7 processor from Intel later this year, you're in luck. Just after the grand finale for its Nvision conference, Nvidia gathered reporters to inform them of a somewhat surprising and apparently very recent decision: the firm plans to enable its SLI multi-GPU scheme to work with Intel's X58 chipset–without the need for an nForce 200 PCI Express bridge chip on the motherboard.
The fate of SLI support on the X58 chipset–intended for Core i7 processors, which are code-named "Nehalem"–has been a question mark for some time now. Nvidia has said that it won't be making chipsets that work with the Core i7's QuickPath Interconnect (QPI), and it had instead proposed that motherboard makers use its nForce 200 chip on their boards. The presence of that bit of Nvidia hardware would then make the mobo kosher for SLI support. However, the company said today that it realized such a silicon solution would limit SLI to a small number of very high end motherboards, effectively roping off SLI from the mainstream of the enthusiast PC market. Rather than be forced into that situation, Nvidia has elected to allow SLI on the X58 chipset–under certain circumstances.
Again, there's
no reason that video cards can't play together outside of driver controls, regardless of the brand of PCI-Express. It's artificial, inasmuch as I can say artificial with a straight face whilst talking about setting up computer hardware and then using it to play video games. But as long as NVIDIA makes
some money.
Which is good news for hackers left and right, since BIOS rewrites for SLI on Intel--and for a laugh, AMD--hardware is starting in 3... 2...
