Can you SLI it?
I didn't see a SLI bridge.
And what is the point of all that when you don't have official support for the gtx680 on OSX? You're just that future releases of OSX wont break compatibility with your setup and NVIDIA'll continue, unofficially, to pump new drivers for the 600 series.
You can enable SLI using HyperSLI patch (on Windows 7). I tried it with two 560 Ti's.No SLI bridge as SLI is disabled. I do no gaming. I actually work in windows about 75% of the time using Solidworks for cad and Bunkspeed Shot for rendering. Shot uses a rendering engine from Nvidia called iRay. It directly utilizes all CUDA cores available. There is no benefit from SLI and SLI can actually cause issues with iRay's performance.
Hmm, what can I say. I know, that my MP can't cover needs of 690, but I don't want to buy another PC just for games for 10-20% performance boost. And don't want to reconnect my shiny Cinema 30" every time I want to play. And don't want ugly box under the table.Hmm tell me?
is a third one possible on the last pci port? even a low speed?
p. S.Then, it looks good in Pro![]()

If I had room for another 680 I'd pop one in tomorrow.
Cubix PCI extension chassis offers 4 double slots. Under Windows you can put in there 4 GPU cards (mac os x has a limit of three-not counting GUI card)
Linux today recognizes 8 or more GPUs (>8 via infiniband linked clusters). Da Vinci Resolve takes advantage of this. Another way is to put in GPU coprocessors with a bigger number of "cores". Tesla k20 has +3000 CUDA cores, double the number of gtx680.
If you remove drives 2-4, yes
I have done Tri-Sli this way.
Have you tried the octane renderer?
If yes what kind of performance are you getting?
Hmm, I tried HyperSLI 0.96 with two GTX 560 Ti on my MacPro3,1, everything worked well. Are you using SLI bridge?Hi all and thank you for taking the time to read my request.
I have a 2011 Mac Pro 5,1 12 core updated with ML and running Win 7 X64 Ultimate in bootcamp.
I was wondering if anyone has installed 2 GTX680 in SLI and got it to work in windows 7?
I have 2 MSI GTX 680 4gb OC (both works well so it dosent seem to be a card problem)
I have tried to install hypersli 0.96 and it seems to install well. But everytime I try to activate SLI in Nvidia Control Panel, the screen starts to flash and graphics controller stops working then Comp reboots.
Tried with a host of driver options as well, but seeing as there is so many I was hoping someone may have done it and suceeded and can give me a helping hand in setting it up?
Thank you in advance !

Was wondering what drivers you all use and do you hypersli in hardware or software mode. Also is there any need to enable anything in the boot windows + hypersli selection page.
Finished installing the Aux PSU. Of course I usually do things a little "Different". I wanted to run the 120v power to the aux psu from the main psu so I wouldn't have to deal with a extra power cord running about. The main psu is inches away so it seemed to make sense. The aux psu also needs 12v in the form of a molex connector. This is so it can turn on and off in conjunction with the mac powering on and off. The likely place to get this power from is from one of the sata connectors in the optical bay. This means you lose one of your sata connections. I wasn't ready to do that so I figured if I was going to be mucking around in the main psu I may as well draw both the required 120v and 12v from there. It all went well.
The cable assay's that come with the unit are nice but not real long. I really didn't want to cut them so I looked for a different solution. Found that if I mounted the psu upside-down & backasswards the cables would reach fine. I didn't like the idea of the aux psu's twin fans blowing air in the opposite direction of every other fan in the case. This could lead to stagnant air in the aux psu. So I opened up the aux psu and just flipped the fans around.
I still run a blu-ray drive and my bootcamp SSD in the drive bay along with the aux psu ! Sweet. I didn't use screws to secure the aux psu and that gave me enough room between the optical drive and the aux psu to slip a Samsung 500gb 840 SSD for my bootcamp.

I clipped a very small piece of aluminum to snake the cables through here.

All cables in place and ready to button up.

Snug as a bug .

Complete !
