GeForce GTX 480 Supports 4-way SLI?

I'm not sure whether all boards that support 3-Way SLI also support 4-Way. The original Evga Classified was not capable of running 4-Way GTX285, although that was because the GTX285 doesn't officially support 4-Way SLI and some fixes needed to be applied. Maybe this time Nvidia will officialy support 4-Way?

Soon after EVGA laid its hands on stocks of GeForce GTX 480 graphics cards, it claims from an internal test that 4-way SLI is possible on the reference design GTX 480 graphics cards. The GTX 480 was advertised to work with up to two more of its kind in 3-way SLI, in NVIDIA's presentations to the press. EVGA's feat of running four GTX 480 cards was possible on its X58 Classified 4-way SLI motherboard, which has room for four graphics cards, and a special SLI bridge that connects to four NVIDIA graphics cards with two SLI interconnect bridges each. EVGA released a special-edition GeForce GTX 285 4-way SLI ready graphics card to go with the motherboard. The EVGA X58 Classified 4-way SLI isn't the only motherboard to support 4-way SLI, the recently released EVGA Classified SR2 also ships with the special SLI bridge. No other motherboard vendor released a 4-way bridge, yet. EVGA demonstrated the 4-way SLI setup with a run of Unigine Heaven, although it did not give away any performance numbers. 4-way SLI is not to be confused with Quad-SLI, which is also a four-GPU SLI configuration, but involves a 2-way SLI connection between two dual-GPU graphics cards (such as GeForce 9800 GX2, GTX 295, MARS). Any SLI-supportive motherboard supports Quad-SLI.

If I'm not mistaken, Nvidia used to not enable 4-Way SLI to promote their dual-GPU products. By not allowing people to run 4 seperate cards, those who wanted the highest performance had to buy 2x GTX295 (or similar). The fact that they would now allow 4-Way SLI is, I think, due to the fact that the GTX480 GF100 produces so much heat that a dual-GPU product is simply not possible to produce as the heat output would simply be too high.

So, 4-Way SLI gets support because their products are not good enough :-)

Not impossible - not economically reliable ;) We haven't yet come to a limit of physical impossibility. Your thoughts make sense because NVIDIA's marketing dep. is a very greedy one :D They wouldn't give a chance just because they were so nice to do so.

Lol. If you boot up this system - electricity in your hometown will collapse :D

is this a Nvidia or a Evga thing?

If nVidia were so greedy, and the combo was possible, they would have promoted 4-way SLI. 2x GTX275/GTX280/ GTX285 cost more than a 295 :p

Russian Federation Antinomy says:

Em, there's another point - the MIO. NVIDIA prefers to make the 1+1+1 triple SLI. And the (1+1)+(1+1) for Quad SLI. And if I understood the EVGA 4-way right, what they did is combine each pair of GPU with an Nforce200 bridge just the way like the GTX295 does. But if the 295 has all this stuff onboard, the EVGA had it on the MoBo.Other boards don't have such a system - that's why they don't support Quad SLI from 4 separate cards. And NVIDIA has made SLI pretty much dependant from MIO connection though before it wasn't so necessary.
