    Uh no, they never said standard GTX 285 could do that, which is why they came up with special GTX 285 Classified cards that could.
     
    HammerON says thanks.

    Scuttlebutt is that nVidia is looking into 4-way SLI as an extension, since more MOBOs are becoming four-slot capable. As of now, though, you have to have a specially-designed set of BIOSs to support the extra interrupts the PCIe controller needs and the teaming coordination across four seperate slots (Quad currently only uses two, and of course three for Tri-SLI).

    If you're using it for folding, isn't the 480 more energy efficient then the 5870?

    So, nvidia already has a very limited amount of these cards produced for distribution, and here you have a vendor hogging 4 puppies for sh1ts? Wow, good stuff.

    I'd like to think of the stupidly rich enthusiasts that have a massive boner for folding.

    Really, It would take a few minutes to press print screen on a bench result, place on mspaint, and upload it to an image host. (or in 3dmark's case, upload an orb, or a GPUz verification)

    vs several minutes spent in changing the CPU cooler, and taking pics of it.

    4-way CrossFire capable motherboards have been around for close to half a decade. So those issues are long ironed out.

    It depends.

    For gaming, some of us demand a certain level of performance. Me, I know for a fact one of my cards can easily handle my native res without breaking a sweat . . . but I can't settle for anything less than x FPS at my native res . . . and I also prefer to game with all the eye candy on, too . . . I'm just a bit goofy like that.

    Do I know multi-GPU doesn't scale well? Yerp. Does it also depend heavily on the game? Yerp. Does it have more of an imp0act at higher res and with the eye candy enabled more than not? Yerp. Does it bother me that some might consider it a waste? Not at all.

    But. Unlike most others, I also put my GPUs to work when I'm not at home or gaming . . . F@H keeps them busy.

    That only happens if both are at stock. ;)
    Both of us knows that benchers rately leave their cards at stock.

    My immediate thought as well. Actually there are three with the fan completely blocked.

    2000w of PSU needed and probably a min of two 360mm radiators and two or three pumps for proper cooling via water.

    Na, the PCBs have that cutout in the PCB, so the top card (closest to CPU) will still get a little bit of cool air through that.

    OMG Evga is B@llZors for even trying this, the heat the heat the heat holy reactor of a power supply, this is more stupid than my setup Evga is 1am3
    Fanboi out-

    Ok, seriously less than 1% of users will use a 4x SLI/CF setup and those that don't use it don't understand why they do it(not to grill hotdogs).

    Looking at the picture they used 2 different PSUs. I recognize modular connectors from an Antec quattro 1200W, and a Corsair HX1000W.

    The SLI bridge connector doesn't look right. Why does the 'bottom' card have two connections and the one above it only have one? Surely it should be the other way around? Unless they are connected out of sequence? (1-2, 2-4, 4-3 maybe?) I guess we now know why the PCBs for these have extra vent holes in the back. :D

    Because it's an SLI of two SLI arrays.

    In 3-way SLI:

    [​IMG]

    With Quad-SLI:

    [​IMG]

    So 4-way SLI is implemented like Quad-SLI, albeit over four physical cards. In that 4-way SLI pic, card 1 and card 2 are like GPU1 and GPU2 of card 1, while card 3 and card 4 are like GPU1 and GPU2 of card 2. So the two sub-arrays are linked.

    Yep. Those fans will be working like mad to draw in enough air. I feel sorry for them. Did they deserve this fate?

    They run at 50% of clocks and 0.7V right? Cause otherwise you could really use it as toaster..

    From all I've heard about their development and dealings with TMSC, they brought it on themselves. It does suck for the industry as a whole.

    Interesting how chip design sounds a lot like software design, which share similarities with legislation and sausage making. It ain't pretty.
