I didn't think I had this issue on my 4,1/5,1 3.33GHz hex with a flashed PNY GTX 680.
One cold-boot later and I now know I was wrong. The PCIe fan runs at 1270 until loaded and then it settles down to 800. Warm boots are no problem, so I'm not particularly bothered, though.
My flashed GTX 680 does not display this issue either.
Do you verify with iStat or some fan reader at cold boot after post? Is this PC 680 with flashed Mac ROM? Some more info would help and thanks for contribution.
The link you provided is for a 4GB GTX 680. Unless you have learned how to modify and write a customized ROM for this particular card, you won't be able to flash it. If you try to flash the EVGA 2GB Mac ROM to this card, you'll probably get yourself a non-functioning card. If you want a flashed 4GB GTX 680, check the eBay for one.I was looking for gtx680 for my mac pro.
Can I use this video card after flashing in my mac 5,1 Mic 2010?

I'm using an EVGA GTX680, flashed with the Mac ROM, and I do NOT have any fan spinning issues at all, in OSX or in Bootcamped Windows 7!
THANKS Abulia for uploading Mac rom.
Don't directly flash the "EVGA Mac GTX 680 2GB rom" to the "MSI GTX 680 4GB card" without modding BIOS and EFI part.
If you did that, you may get a GTX 680 4GB brick card.
I tried the MSI GTX 680 4GB Twin Frozr III OC edition and it works.
1.apple boot screen --OK.
2.It works on Mac OS X 10.7.5 but shows up GK104 in OpenGLviewer and Luxmark. (On 10.8.3, it shows up GTX 680 normally.)
one issue has to solve:
I only got 2.5GT/s. Will try to get it running 5.0GT/s.
Open your private message.Hello! I have the same 4GD card as yours. Could you please send me your modding BIOS and EFI part rom - which you wrote about in your post. Thank you in progress. With best regards.
There is a working 4GB ROM linked in this thread.
I just got off a plane and am very tired. Installed and did the dump. Works in OS X and Boot Camp (with boot screens) with no issues. I'll run some benchmarks tomorrow.
[Edit] Okay, I relented with one benchmark before bed.
When I flashed your rom Into my gtx 680 it loads efi bootloader where I select either windows or mac then spin wheel then freezes spin wheel. No op-sys. Someone was wondering if the rom could be currupted? I didn't know if you could help at all?
The way you did also works on your card but the better way is to use the original BIOS.
I use Mac K5000 EFI on the pc GTX 670 (reference card) and it works on mac with boot screen (Mac K5000 rom revision is 3730 and Mac GTX 680 EVGA is 3731).
Yes. Maybe all GTX 6xx ,Titan ,K4000 and Tesla K20c could show boot screen with Mac K5000 EFI part on Mac.
Thanks NVIDIA for offering drivers.
So, I'm up to flashing my GTX 680 now that this is the only way I can use Bootcamp since the Bootcamp tools don't support APFS and without a boot screen there's no way to get back
My question there is: To flash the GTX 680, can I put a GT 120 in instead of an old ATI card? Does it have to be ATI for some reason or my old GT 120 will also do? I have no other card to pop in currently.
Please light my way up, I really don't want to screw up flashing.
Thanks.
I am also using APFS Mojave and Windows 10 EFI mode. The absolutely worst combination for dual boot cMP. But I can’t see why I need a flashed card.
1) terminal command allows me to switch between Windows and MacOS.
2) BootChamp / Boot Runner may able to do that as well.
3) PRAM reset always bring you back to MacOS.
4) you can dust boot to any HFS+ MacOS, then further go back to APFS MacOS.
There are so many ways to do it. It is absolutely not “no way back”.
Anyway, to flash a GTX680. You don’t need any other card but just the 680 itself. In fact, IMO, remove all other cards is better (avoid a accidentally flash the wrong card etc).
https://forums.macrumors.com/threads/how-to-boot-camp-without-a-boot-screen.2114788/Wow, thanks for your reply!
That’s a lot of things I was not aware of What terminal/command line commands can you use to switch back once in Bootcamp? I thought Bootcamp would not see the APFS volume as an option...
I didn’t know you could flash the 680 if it was your primary display... I’ll give it a try.
Anyhow, I plan to save the original ROM contents first in case any issues would arise, so I’ll see if it’s willing to cooperate )
Thanks a lot!
Cheers,

will it work with gigabyte or msi gtx 680?I just got off a plane and am very tired. Installed and did the dump. Works in OS X and Boot Camp (with boot screens) with no issues. I'll run some benchmarks tomorrow.

Found it - skillfully hidden in plain sightI am trying to keep my beloved Mac Pro 5,1 running and want to move to OS 10.14. I can't find the gtx680mac.bin file. Does anyone know where to find it?
