So i was planning on getting an evga gtx 680 to flash it to the mac-edtion of the card.
I´m completely new to the whole ROM/BIOS/flash things, so it would be cool if someone could answer me some questions before i create a complete mess.
1. Will the card work completely like a factory-original-genuine-authentic mac edition gtx 680 after the flash? (Assuming i did everything right)
2. Will all Adobe Programms be supported (some may need whitelisting, i heard about that) ? Are there known incompatibilities?
3. Will this card work in Bootcamp like a regular gtx 680 (Run all the games, programs etc)
4. Is it possible to flash via Bootcamp on my Mac Pro in Win 7, or do i need an extra computer running Windows?
Since i have never worked with nvflash or anything similar, i have no aidea where to start. If anybody could give me tips on how to get started or even the whole process, your help would be greatly appreciated. (If there is no Place for such discussion in this thread, i would really like to discuss this via P.M.)
All your help is welcome
-Once flashed it will behave like an EVGA Mac Edition GTX 680, everything the "official" card can do, the flashed card can do.
-It will work in windows\boot camp without issue, just install the latest Windows Drivers from Nvidia.
-To flash the card in windows\bootcamp:
download EVGA Mac Bios: http://forums.macrumors.com/showpost.php?p=17132316&postcount=111
rename the file to: gtx68mac.rom, put it in the same directory you unzipped nvflash too (put in nvflash folder)
download the Windows version of nvlflash (works with 32 bit and 64 bit):http://www.techpowerup.com/downloads/2231/nvflash-5-134-0-1-for-windows/
Open a command prompt within windows (right click on command prompt, run as admin)
change to the directory with nvflash
backup your original Bios: nvflash -b my680.rom
flash the mac bios: nvflash -5 -6 gtx68mac.rom
it'll ask you two questions, hit "y" for both.
Make sure the GTX 680 is the only card installed when you do this.
I did exactly this using a windows machine. I typed line by line into CMD prompt and all seemed fine. But when I install it on my 2009 Mac Pro and turn it on, the computer does not turn on. no lights or anything. I made sure to flash the card (EVGA GTX 680 2GB) with no other cards installed. When I put the card back in the PC, the PC works. I used power cables to power the card from the Mac - 6 pin PCIe mini to PCIe 6 pin (x2). the 680 is the only card installed in the Mac. Am I missing something?
