Mar 02, 2019 Today I have flashed a GTX 680 4GB with a Mac BootScreen, but I do not know how to test the Bootscreen. Do you have any idea how I can make my 15' MBP 2018 to boot from the eGPU? It's always booting from the internal display @goalque, you know a lot about those things. Do you have a tip?

No you can't, but read on. 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. We assumed that NVIDIA could release a new ASIC codenamed 'GK114' or 'GK204,' which features higher energy-efficiency, and GPU Boost 2.0.
A Reddit user claims that a simple BIOS flash of the GeForce GTX 680 could turn it into a GeForce GTX 770. 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 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 file can be found here (try it at your own risk). 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. The BIOS just has made-up clock speeds that could run on some GTX 680 cards, but could be unstable on most.
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 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. Third-rate companies often get away selling rebranded fake graphics cards in developing markets using this method. For example, they buy cheap GeForce 210 cards and sell them as GT 630 for twice the money. 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. 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.

#1No doubt the core and boost clocks are doable for most GTX 680's, but that 7000Mhz effective memory is going to find more than a few 680's wanting.
