When explaining to your best customers why they can’t purchase two of your $649 video cards for themselves without also buying a $5K PC built by someone else, it’s probably not good idea to use a shaky excuse with an embedded insult. As far as I can tell, Quad SLI requires a motherboard BIOS update, a fairly high-wattage PSU, sufficient case cooling, and a single SLI bridge connection. I’m not entirely sure what to make of this statement. This “complexity” line is not just some off-the-cuff statement by one guy at NVIDIA, either it’s practically corporate policy, repeated with consistency by several of the company’s representatives.

NVIDIA says Quad SLI will, at least for now, remain the exclusive realm of PC system builders like Alienware, Dell, and Falcon Northwest because of the “complexity” involved. That should fit fairly easily within the power envelope of today’s best PC power supplies.īefore you get all excited about the prospect of dedicating 96 pixel shaders, 2GB of memory, and 1.1 billion transistors to pumping out boatloads of eye candy inside your PC, however, there’s some bad news. NVIDIA says each 7950 GX2 should pull maximum of 142 watts in real-world operation, so that a pair of ’em would require less than 300 W total.

That makes sense, if you think about it, because only two images need to be combined-one from each GX2-in the final compositing stage of a Quad SLI rendering mode. Apparently, one of those two SLI links was superfluous. The ring topology we discussed in our early look at Quad SLI has been modified for the GX2. You may have noticed that the GX2 has only one “golden fingers” SLI connector on it, not two like on early Quad SLI cards. The GeForce 7950 GX2 was designed for use in Quad SLI configurations and is fully capable of working in them.

As usual, though, the savvy user may create a custom profile for an application if needed. If there’s no SLI profile for a game in NVIDIA’s drivers, the GX2 won’t be able to accelerate it with two GPUs automatically. Of course, in the background, the usual SLI stuff is happening.

The drivers default to multi-GPU mode, and you won’t see any pop-up messages reminding you to enable SLI like you will with dual-card rigs. Frustrating, but that’s life with SLI.īeyond the annoyance of having to pop in and out of multi-monitor mode manually, the GX2 generally appears to work like any other video card, with the GPU teaming operating transparently. In order to harness all of the GX2’s 3D horsepower, though, you’ve got to switch into multi-GPU mode, at which point one of those two displays will go blank. If you’re in multi-display mode, one of the GX2’s GPUs will output to two different displays concurrently and drive them like any other card would. Once again, focus groups prove they know nothing about good interface design.) (This control panel, incidentally, is focus-group tested, just like ATI’s Catalyst Control Center.

Here’s how the option looks in NVIDIA’s fancy-pants new driver control panel. As with a dual-card SLI setup, you’ve got to switch the GX2 manually between multi-GPU mode and multi-display mode. Intel-based mobos and the like are happily on the GX2’s compatibility list.Īnother artifact of SLI that mars the GX2’s operation affects multi-monitor setups. I should note, by the way, that running a GeForce 7950 GX2 does not require an NVIDIA SLI chipset or even an NVIDIA chipset at all. Many of the most popular mobos are on the list already, but not all of ’em, so you’ll definitely want to check before buying a GX2. NVIDIA has put together a list of mobos and BIOS revisions that it’s confirmed will work with the GX2 and has plans to post the list on its web site.

Having a couple of GPUs in a single slot behind a PCI-E switch can cause device enumeration problems, so most motherboards will require a BIOS update in order to work with the GX2. The GX2’s PCI Express switch presents another problem, simply because it’s unfamiliar. Textures and other data must be uploaded to each GPU and stored in each GPU’s associated memory. Yes, the GX2 has about twice the memory bandwidth of a normal card, but functionally, it has a 512MB memory space. Yet that RAM is segregated into two 512MB pools, one for each GPU. You may see the 7950 GX2 advertised as a 1GB card, and it undeniably has that much video RAM onboard. Source: NVIDIA.īecause this is SLI on a card, it has some limitations.
