Until I figure out how they pulled off quad SLI on 780s

I have picked up a fourth GTX780 and it's currently assigned as a PhysX GPU in the Nvidia control panel. Has anyone figured out how they got this working? http://www.youtube.com/watch?v=bTMtOb2uRoo

Or are they doing the same thing that I'm doing? Board is ASUS Maximus V Extreme
 
What does it say in your "Configure SLI, Surround, PhyX" panel? Does it say "4-way SLI enabled"? If not, make sure you have your "SLI configuration" area set to either "Maximize 3D performance" (for 1 panel) or "Span displays with Surround" (for multiple panels). Set your "PhysX settings" to "Auto-select."

Be sure to download GPU-Z to validate that 4-way SLI is enabled AND that you're PCIe 3.0 is enabled (should be no problem with your Z77 board).
 
They don't support 4-way sli, only 3-way at the moment. It could change later on though. I think those people are using some special bios/driver, for it to be enabled.
 
I had seen some boxes have 3way SLI ready logo's, but on my EVGA 780 boxes (same as you posted) it did have 4way SLI ready.

I was wondering which one was correct.
 
That's absolutely ridiculous that the "flagship" NVIDIA card can't do 4-way. The TITAN is an outlier...why should it be the only card that can do 4-way? Stupid.
 
bump for your video cards being worth more then my 98 accord!
 
Only system builders partnered with NVIDIA can build systems with 780 quad-SLI. It isn't a consumer option.
 
Congratulations, you now own the world's most expensive PHysX card!! LOL :D

I call bullshit. How would they update drivers. Im sure if was magical drivers they would of been leaked by now.

It is likely accomplished by a custom BIOS. Once that leaks - we'll all be in on it.

no, that would be a titan.

might sell these 4 and go for 3 titans in an even trade (money wise), then grab a fourth

interesting about the box. I have 2 msi and 2 eVGA. gonna look

I'd contact EVGA and ask them about it. Seems since they put it on the box they'd have responsibility to you. Maybe they have some super secret way of activating it with a custom BIOS, etc...? I certainly wouldn't just hand them another $3K after this.
 
$650 top 700 series part can't do quad SLI? bwahahahaha! Probably someone just needs to swipe the firmware from one of the special cards, since they'll probably just use the regular drivers.

Remember this is what happened with 670's. I have four of them now running in 4-way SLI. With the first drivers however this was not supported.
 
they launched in May of 2012. do you recall when they added the quad support?

In the end of may, with the release of the 301.42 drivers. They had a change of plans and decided to enable it. I'm not sure if they plan to do the same with the gtx 780.
 
I hope so. I realize in my particular case I'd have likely gained more by going quad titan, but a 2 or 3k buy in seemed more reasonable at the outset. 11M+ pixels isn't easy to push
 
I have 4 470's running Quad SLI on a old Rampage III Extreme. Took a custom bios on the mainboard and custom bios on each video card. Quad SLI still activates in each driver without any driver hack. Annoying amount of work to get it running. My wifes box with 3 570's and a 470 running Physics is actually faster. If you need help locating the bios mods send me a PM and beware you can destroy cards with bios flashing. Warning.
