When Intel launched its Core i7 processors and X58 chipset last year, almost all X58-based motherboards featured SLI support from Nvidia—except, strangely, for Intel's own DX58SO "Smackover" mobo. Now, three months later, Nvidia says it's finally struck a licensing agreement with Intel, bringing support for multi-GPU GeForce configs to the DX58SO at last.
According to Nvidia, the DX58SO supports "any combination" of GeForce graphics processors, including Quad SLI with a pair of GeForce GTX 295s. Unlike with the old Skulltrail dual-CPU platform, Intel didn't have to put an Nvidia PCI Express controller on its latest motherboard. Rather, Nvidia allows SLI licensees simply to embed a key in their motherboards' BIOSes. ForceWare drivers enable SLI if they find the key.
So far, SLI support has also found its way into X58 motherboards from Asus, DFI, ECS, EVGA, Foxconn, Gigabyte, and MSI. Like high-end Intel-based boards of old, those X58 offerings (and the DX58SO) also support AMD's CrossFire multi-GPU scheme.
