    Mac Pro 5,1/10.9.2/EVGA 4 GB 670 SC.

    Installed the newest web drivers and had no DVI output. iStat Server showed the machine had booted up and was running normally. Had to reset my NVRAM to get the stock drivers back.

    Just checked the driver info page. The only 600-series card listed as supported is the 680.

    That's because the only official Mac Card was the GTX 680 by EVGA. The other cards would work, though, unless flashed, you will have no boot screen.

    Now I'm more confused: the control panel tells me that 331.01.01f01 is installed, and that it's the stock OS X driver. It's also the latest one listed on nVidia's website.

    The NVIDIA Driver Manager control panel has several functions:
    • Let you choose between the nVidia driver and the Mac OS X driver
    • Let you enable ECC on the K5000
    • Let you check for updates of the nVidia Web Driver

    The first tab "Graphics Drivers" shows you which driver your system actually uses. The third tab "Updates" shows you, if the nVidia Web Driver is up to date. It is possible to have the latest nVidia Web Driver files (331.01.01f01 at the moment) on your system and using the earlier Mac OS X driver (310.40.25f01).

    Under certain circumstances the older Mac OS X driver is used even if you have the newer Web Driver installed. I noticed this once on my system and had no reasonable explanation. But after switching to the Web Driver the setting remained so after reboot.

    You can look in the "Apple System Profiler", too. There is a section called "Software/Extensions". It is a long list. Scroll down until you reach the extensions beginning with the name "NVDA…". In the column „Loaded“ you can verify which driver is currently used by your system. And you see the Apple supplied driver and the nVidia Web Driver. Obviuosly, the Web Driver has the suffix Web attached.

    I hope this clarifies some of the confusion.


    BTW - On my EVGA Geforce 680 GTX 2GB (flashed with the official BIOS) the DVI output (dual-link) works as expected.

    331.01.01f01 driver is not good for the original MAC-Version EVGA GTX 680 as well. DVI-D will not recognise the monitor after the driver upgrade. You should disable the new driver from System Preference and revert back to OSX drivers for now until it is fix. You will notice that CUDA also will prompt you to update your drivers (but there are no CUDA drivers released yet).

    I can't confirm your findings: DVI output works just fine with my retail EVGA GTX 680 (Mac version) and the latest webdriver. also the CUDA driver updates to the latest version (5.5.47).
