I'm really surprised to see that it only takes waiting, but that's great news!
And here I was spending time trying to track down all the other threads where people had problems, to see if I could identify the differences.
Last time I check it didn't work. I think it crashed during boot on my MacPro3,1, but I could be wrong.Thanks for mending the .rom with the upper DVI! As you perhaps might have read, I recently acquired a GTX-680-FTW-4GB that I flashed Mac EFI with your rom. May I ask if you have any trouble with booting Windows 8/10 EFI.

1. drivers updated to the latest 372.90, known problems?
But it does seem that switching to Windows BIOS install fixes it. And since the problem has existed for so long, I doubt it's just 372.90.
Maybe there is more information over at Netkas. I haven't looked there.
So... Here's the bottom line. If you have a copy of your original BIOS before flashing (you should). Make all the settings on the first tab (Common) of the Tweaker match. The new Mac rom settings on this first tab should ALL match your original unflashed PC rom.
You can use "Open BIOS" from Tweaker to open your original PC rom file and verify all the settings.
There's no risk, your just setting everything back to the way is was when you bought the card. You just now have the EFI for the boot screens.
I would like to know if it is absolute mandatory to tweak all settings in the first tab. What about the power settings? I noticed that your tweaked rom has a less power settings for the GTX-680. As for the 250-300W - settings in the original FTW rom file - I'm worried that my GTX-680-FTW-4GB will go over te top and draw that TPD from the PCEi and the both 6 (used the with my non-ME GTX-670-FTW-4GB) pin power cables. Your input will be appreciated!
If you want to play it safe, you can just keep Fl0r!an's settings.
As you can see especially my PCIe Booster A is spiking in the ~85's Watt of TPD. What is the bandwidth for the limit for both Boosters A/B as my GTX is drawing ~10 Watts more the specced power from Booster A (75W). Do I have to use the bios tweaker application to lower the maximum draw and what will the outcome of this tweak in performance. Directions much appreciated!
Thanks for explaining this, appreciated. So my assumption that it would draw the power equaly from all three sources, PCIe and Boosters A+B (xW/3) is defenitly a fals one then.
Not sure if I should keep this card as it doesn't meet the specs of the 5.1 mobo after all. Even when using 6 pin cables for both the 6 and 8 pin connectors on the card, the power drawn from the 8 pin is >75W. Oh mai....
Cheers
Could someone link a video or step-by-step instructions for a newb like me?
I am very late to this discussion having only secured a GTX 680 4GB a few months ago. I have never flashed a graphics card before. I have downloaded all the mentioned tools but then became concerned when there was mention of "bricking" the card if done incorrectly. Could someone link a video or step-by-step instructions for a newb like me?
I was also much too late to the party
Yes, I wrote step-by-step instructions here.
The GTX680 is pretty easy. There is always some risk, but I can't recall anyone "bricking" theirs here. Don't do it during stormy weather with spotty power.
If the ROM you've downloaded is Dr Stealth's ROM, I suggest using Florian's ROM instead, which is the one I linked to in the instructions. Also, the current version of the flashing software doesn't do anything on the GTX 680 any more, so you'll have to get the older version I linked to.
Did you ever get that long boot time sorted out?
I so appreciate your link. Unfortunately, the link to the older version of NVflash that works with GTX 680 cards isn't working. I am not sure if I have a working version or not. As it turns out, what I thought was a 4 GB card turns out to be a 2 GB card. I should have been more aware. Sigh.
