In conclusion, this 'GTX 770' mod is nothing more than a combination of a custom GTX 680 BIOS that adds higher clock speeds, and a custom INF file that changes the card's name string. Even between officially rebranded NVIDIA graphics cards (such as GeForce 8800 GT to 9800 GT), the device ID is changed, so there's no reason why NVIDIA won't do the same with the GTX 770. For example, they buy cheap GeForce 210 cards and sell them as GT 630 for twice the money. Third-rate companies often get away selling rebranded fake graphics cards in developing markets using this method. The string from the INF file is used in Windows for display purposes only the graphics driver does not use it for anything else certainly not feature detection.When your GTX 680 manages to be stable with the new BIOS, the higher clock speeds obviously work to get you that 5-7 percent performance increment. We created four additional GPU-Z screenshots to serve as evidence that just by modifying the INF file, you can make the card appear as anything you want. The BIOS just has made-up clock speeds that could run on some GTX 680 cards, but could be unstable on most. Everything else is running great, Ill just work on fixing the intel drivers. ![]() #HOW TO FLASH NVIDIA GTX 770 FOR MAC DRIVERS#We tested the BIOS with some of our own GTX 680 cards, and found it to be nothing more than a modified GTX 680 BIOS (for increased clocks) with a modified driver INF file that makes the GeForce driver display a different model name. Flash Nvidia Gtx 770 Drivers I Get Also, nvidia will boot straight from the drive but has some artifacts and only shows 7mb. I’m running high Sierra 10.13.3 and the latest cuda drivers and k5000 drivers for 10. #HOW TO FLASH NVIDIA GTX 770 FOR MAC INSTALL#I have a 5,1 2012 pro and followed all the steps to an initially successful install of an EVGA GTX 770 2gb. The BIOS file can be found here (try it at your own risk). I have run nvidia gtx 980 on mac pro early 2008 (3,1) just a few roundups with driver choice and of course no boot screen, but CUDA works. The BIOS runs the card at 1059 MHz core, 1125 MHz maximum GPU Boost, and 1752 MHz (7.00 GHz GDDR5-effective) memory, yielding a memory bandwidth of 224 GB/s. The BIOS ROM image, which probably works with reference-design GTX 680 boards was posted, along with a GPU-Z screenshot of a 'GeForce GTX 770' obtained this way. The majority of GTX-680 cards were intended for use in Windows PCs and do not have Mac firmware, but as explained by Christian Stueben this does not mean it will not work, only that you will not see. Supported Technologies SLI More > CUDA More > 3D Vision More > PhysX More > TXAA More > Adaptive VSync More > GPU Boost 2. ![]() The GTX-680 will work in your Mac and will be faster than the original card. We assumed that NVIDIA could release a new ASIC codenamed 'GK114' or 'GK204,' which features higher energy-efficiency, and GPU Boost 2.0.Ī Reddit user claims that a simple BIOS flash of the GeForce GTX 680 could turn it into a GeForce GTX 770. (13,694 points) 3:55 AM in response to Snookams. When we learned that NVIDIA's upcoming GeForce GTX 770 uses a GPU not unlike the GeForce GTX 680 in specifications, we overlooked one possibility, that it uses the same exact chip, the GK104. ![]()
