These are single-slot water blocks designed for the new single-board GTX 295s. Theoretically, a single standard ATX motherboard and case could now accomodate seven GTX 295 cards (14 GPUs!) The water cooling would eliminate the cooling problem, however power and PCI-E lane issues would remain. Has anyone looked at these with the thought of increasing GPU density?
Though…I don’t know what kind of power supply you’d get to handle SEVEN cards. You’re also looking at spending $5k on the cards + water blocks alone, plus probably another $2-3k for the rest of the system.
Good luck getting a BIOS that works with that many GPUs… (also I don’t know what the theoretical maximum for our driver is but I am pretty sure you will hit BIOS problems long before you hit driver problems)
Even though the board gets thinner, I don’t think those are single slot widths. Look at the water hose barbs at the top, they angle sideways, not up, and don’t really leave room for another card right next to it.
That’s good to know about the driver. The (8 GPU) BIOS limitation seems more like a chicken/egg problem, in that, the manufacturers are not motivated to provide support for something that is (used to be?) physically impossible. If BIOS support was available, what other reasons might people have to not trying to use single-slot GTX 295 cards side-by-side? The “Best PSU solution for 4 x GTX 295” thread has a lot of clever solutions for providing power, so I can’t see this as being insurmountable.
An old thread of mine is revived - to no purpose. tmurray was right on both counts; there is still no motherboard with BIOS support for 14 GPUs and bandwidth will be bad no matter how many nf200 bridges are installed. This is a future technology. The current state of the art is GPU clusters (shameless plug).
