Anyone know much about this?:

This sort of pisses me off that nVidia has this on that Quadro series but is hiding it from gamers.

"Feature Available only on Quadroplex"

So... you must buy a $10,000 machine to do what you can accomplish using a TH2Go.

And you pay $10,000 to unlock it in your regular old Forceware drivers. I'll explain how I happened upon it. I was installing a 3rd GTX 260 in my system. While the hardware was installing I happened to have the nvidia control panel open. It sorta freaked out during the install and showed the Quadro Metroplex grid SLI window to me. Needless to say I was a bit dumbfounded, so I went searching to figure out just what the heck it was. Too bad the menu was gone after reboot. :cry:

This stuff is software locked in the driver just like SLI is. This is not a hardware limitation. It's using the same key code setup as SLI does to unlock features if the mobo manufacturer has purchased the liscense. Makes me wonder if there couldn't be an option in RivaTuner advanced setting to turn this stuff on. There already has been Quadro emulation in RivaTuner forever.

Find out what the Quadro equivalent of the GTX260 or GTX280 is, find the relevant firmware and flash it.

Bang, instant Quadro, instant mosiac SLI. ;)

(Obviously not covered by warranty or nowt. ;))

I like this guy. He's smart.

I think it's the Quadro 3700 that is the 260 equivalent? From what little searching I did turned up, anyway. Got to be a BIOS somewhere...

I've got 4 260's, so I might attempt it. Problem is I think this is tied to mobo detection to turn on the metroplex features. SLI and other nVidia capabilities are always detected via checking for specific hardware IDs in the Forceware drivers. This is what makes SLI work on lisenced X58 mobos and not on unliscensed 790FX mobos. That means someone would have to make a hardware emulator driver that makes windows think there is a piece of hardware installed that isn't. RivaTuner has been able to fake video card hardware IDs via the nvbootstrap thing, donno if faking a mobo is possable in the same fashon though. One would think it would be plausiable. You'd need the device ID to do it though.

nVidia would go nuts if someone hacked out the checks in Forceware, but they couldn't do much about it if someone made a 3rd party utility to force a different device ID on hardware in your system.
