NVIDIA Do-It-Yourself Quad SLI Launched 169

Spinnerbait writes "Today, NVIDIA will be releasing their Forceware v91.37 drivers and with them will be officially endorsing Do-It-Yourself Quad-SLI. HotHardware has put together an article detailing the steps necessary to assemble and configure a high-end Quad-SLI rig, and they give some thoughts regarding XHD Gaming and its associated costs. Those of you that are hell-bent on gaming ultra-high resolutions (1920X1200 or 2560X1600 for example), along with the highest available image quality, might want to give one of these setups a look." Before making a purchase I would recommend building that water-cooled credit card first.

      Doesn't matter, nVidia needs to showcase that they're at the forefront of GPU technology. Its a type of advertisement, word of mouth stuff. Consumers that hear about this will automatically link the best video cards to nVidia's product line.

          The question is though (having not RTFA yet): will this work on Linux, and what boards offer four PCI-E x16 slots?

          I can't say one way or the other about Linux (yet). You don't need four PCI-E x16 slots though. This is based around the nVidia 7950 GX2 [], which connects two graphics processors to the motherboard via a single PCI-E slot. Each of those takes up two slots worth of space (in fact,it's two boards connected together) but the high-end single-GPU boards (e.g. 7900GTX, ATI X1900) do so as well. Most SLI motherboards leave quite a bit of room between their x16 slots, so the physical installation should rarely (if ever) cause a problem.

          In case anybody cares: apparently during development, they did build a few dual-GPU boards that required two slots -- but they were never put into real production.

        • what boards offer four PCI-E x16 slots?

          The new Mac Pro has four PCIe x16 slots, and some built-to-order options have 4 nVidia GPUs. As far as I know, however, you will need to run something other than OS X to use SLI; Apple just advertise it as supporting 8 displays.

            If you read the specs of the Mac Pro - it has 4 x16 physical slots but it only supports 1 x16, 1 x8, 2 x4's lanewise. It is not 4 full x16 lanes of bandwidth according to the specs.

          It's tremendously important to both note and keep in mind that the reason why any individual would purchase an SGI system is two-fold.

      Oh well. I'm in that 1%, so it's useful to me. Dell alone is selling some 4000 240xFPW monitors a week, that alone comes pretty close to 1% of the total PCs sold. That doesn't include the 30" that dell and apple sell, nor any other 1920x1200 resolution monitors from other manufacturers.

      Exactly. The triple cheeseburger at your local burger joint is the same way and exists for the exact same reason.

      If a $1200 product is available, people can feel good about the money they saved by purchasing the $600 product and laugh at the people wasting their money on the bigger item.

      If the $600 product is the top of the line then less people will buy it, they'll get the $300 item instead.
    • It would be alot ore than 2% or 3% if Nvidia released quadro versions of their consumer cards. Artists and engineers really could use this more than gamers. Aren't quadro's just consumer cards with different drivers? THis is why Nvidia's drivers are closed source.

      But still cool for gamers but even greater for more productive uses for this when money is involved. I think archcad and proengineer would scream on such a system.

    Died about 2 pages into the article, 1 minute after its /. debute... oh well. A new record perhaps?

    From what I've read so far however, unless you have a big screen HDTV that you game with that supports high resolutions with a fast response time and refresh rate(1% of the gaming market), you WILL NOT need the ultra expensive quad SLI.

        33MB? Ouch, are all the Windows drivers that bloated?

        Remember, this is a "Unified Driver." That means it has drivers for a huge variety of video cards in one big, tidy package. I also most likely includes stuff for multiple languages, only one of which you'll actually use. Also, with the 9x.xx release of nVidia drivers you get both the "new" display driver interface (based on a web browser motif) and the "classic" interface (what we all know and have loved for the last five years or more).

        Add all that up and you get a 33MB installer. The actual driver code, however, is far smaller. Not all of that 33MB ends up on your hard drive after the install is done. It's not bloated, it's just aimed at a very wide array of possible applications, and nVidia wants to put all that in one installer to simplify things for the end user. Bloat implies there's a lot of cruft in there, and that's not the case.

    Most of the comments thus far are replies to some jealous asshole, so I'll try to steer this back on topic.

    It's been possible to do for a while now, although it required some effort. From the benchmarks I've seen, QuadSLI is almost counterproductive for resolutions at or below 1600x1200. It does have a reasonable advantage in FEAR, but most other games showed very little improvement. That review didn't cover the 1920 and 2560 resolutions, but that's where the advantage should be quite significant. Of course, whether it's worth it or not depends on how many more hours you'll have to spend flipping burgers to pay it off.

    They were able to get 78.9 FPS with Prey but only with 4-way full AFR (Alternate Frame Rendering). There is a big issue with serious gamers and this configuration.

    On 4-way AFR the driver builds a display list and sends it to a GPU that isn't busy. It is possible to have all four GPUs busy (rendering frames) while the current frame is being displayed and a new display list is being generated by the CPU. This means what you see with 4-way full AFR can be up to 5 frames later than what is going on in the game engine. At 78.9 FPS, this can translate into nearly 64 ms of latency which is enough to get you killed if you're a serious gamer.

    Serious gamers with Quad-SLI are going to want to use SFR (Split Frame Rendering) which cuts latency quite a bit but takes a performance hit to the FPS. There are definite inefficiencies to 4-way SFR with having all four cards render portions of the same scene vs 4-way AFR. You generate 4 times as much display list info (GPU fifo data) and you have to replicate more data and uploads (if textures don't fit into the 512MB memory) across the GPUs.

    I'm not sure if the Quad-SLI supports an AFR/SFR hybrid where you can have 2X2 (2 GPUs working on SFR each in AFR queue) - this might balance the performance vs latency issue better.

      • Well, shit. 4 core on one card then. I don't need to RTFA again. Personally, I just need one card with a lot of power that can stay cool without a refigerator. Put it in the iMac and I am a happy boy.
    • The term "dual core" is completely meaningless with respect to graphics cards- due to the parallelized nature of the core, it's the exact same thing as doubling the number of pipelines/shaders. In other words, if you want a dual core GPU, just wait and buy the next generation card.
