GTX680 4GB - ROM Image - Full Boot Screens, Full Clock Rates & PCI-E 2.0 - 5GT/s

Which ROM did you use? I'm guessing the Stealth one from the #1 post, I'm getting ready to flash my Zotac. Can you confirm if all the ports work also? Thanks.
Amazing. Just upgraded my Mac Pro 3,1 with SSD, 24GB ram and a GTX680-4GB. Huge thank you for providing all this great info. Now on to upgrade to OS X 10.14.
Hi,
I am new to flashing and searched the Internet. I've found this thread that starts with Dr.Stealth some years ago.
I own a Mac Pro 3.1 and want to use a GTX 680 Classified 4GB. I have connected 2 cables (6 pins on the macpro motherboard and 8 pins on the videcard)
The mac pro 3.1 starts ups but i get no screen. After a while the fans are becoming louder and are working harder (i think)
What going wrong here ? I was wondering if i could follow the procedure from Dr. Stealth to flash the card, but nothing happens.
Should i first flash the card in a windows pc ? or should i get a screen after a while with the GTX 680 4GB Classified ?
Help is appreciated !

Did you tested with El Capitan? Nvidia GPUs are know to not work with hacked 10.12/10.13 installs, it's an unintended consequence of the AMD drivers patch.
Hi,
You mean the power connections?
There are 2 cables from the 6 pins connector on the board to the 8 pins connector on the card. (2 cables)
After 2 minutes after power-on the fans go like crazy and nothing happens? The Fan on the GTX680 4GB is spinning, but no screen after all
Any ideas ?
Thanx!

A GTX 680 is only 195 watts-it shouldn't be be a problem for a stabile Mac Pro. I believe flowrider was asking about the output connections since what model of outputs you have depends on which ROM with which you should flash your PC card.
Your card however should work once the OS drivers load up though OOB with macOS dependent on the OS you are running-but being a Kepler based GPU their basic drivers have been embedded for a while. The 3,1 is a bit out of my knowledge base-but I believe it must be flashed prior to use in machine due to the OS limitations, but it may only need web-drivers installed prior to use. For sure though-match the output ports of your card to the ROM you want to flash to your card so it functions as "normal" as possible.

Gents,
I just flashed a Zotac 4 Gb. All is working fine EXECPT the cMP does not resume from sleeping. You hear it wakes up but the screen stays black. This seems to be a known problem with Zotac models.

I have also a EVGA around with 4 Gb. Works lovely, 100% ok
I'd say keep hands off zotac
cheers

Yea have an EVGA and this happens every once and a while. Usually if I leave it the screen will eventually wake up some time later, like 5-10 mins.
I flashed my 4GB Zotac GTX 680. Works OK except no displayPort. Also waking from sleep is iffy. Other than that, it works well. HDMI and DVI ports all work though.

Bad news(
Display port is critical for me, sleep mode - is VERY critical.
Maybe someone has better experience with this device?
Hi,
I have exactly the experience and ended up selling this card. Better stick to evga or Nvidia. Zotac has been a huge source of trouble and wasted time.
Cheers

Hi Guys,
I flashed my Asus GTX680 DirectCU II 4GB card successful with @Fl0r!an version, but as we know, it is an EVGA Rom, so hardware information tools now display a EVGA graphics card.
I there a way to change the subvendor name inside the firmware.rom? I guess, that not the name itself is stored somewhere inside the firmware, but it's Hex Value. All vendors have an hexadecimal Vendor ID: klick for example:
EVGA (3842)
ASUS (1043)
I searched the romfiles for these Values with a HexEditor, and i found them, but i found them multiple times and i am not sure if i should try to change them or not...

Hey guys,
I know I'm late to the party, I'm getting used to it...
I've attached a modified ROM which will enable all ports in OS X. My approach is quite different from what MVC hinted here, the result should be similar though (anyone who can make an IOReg dump will see what I did to the EFI).
Only drawback is that you'll lose the PCI section in system profiler (which isn't bad since it makes the ROM less attractive for those eBay douchebags). Still full boot screens and OS X on all 4 ports, 5.0GT/s should work, too.
I didn't touch the VBIOS portion of the ROM, so any card that can run the ROM in the first post of this thread won't get bricked by mine either.
Thanks @Rankel for testing it!
FYI...Successfully flashed a GTX680 4GB PNY Enthusiast Edition, both DVI working, and pcie info in System Profiler is back in Mojave. Yet, recorvery mode, and Mojave installer boot to blank displays...Thus, I can't disable SIP...Any ideas?
Thank you kindly for this. I have a Gigabyte GV-N680OC-4GD which replaced my ancient ATI 5770 card which I flashed with the ROM from post #1.
I removed the write protection and used the "overridesub" command when flashing the card. Voila! Grey Boot screen
back to life on my MP5.1
Be sure to connect the 8pin and 6pin so the card gets it normal power. Its a requirement.
I have a 27" cinema display connected as the main screen with mDisplayPort to DisplayPort
and second screen connected to the DVI. One of the DVI ports is missing after the flash, but don't need it.
Thank you again.

Had bookmarked this post for a long time and finally got around to flashing my Galaxy GTX680 2GB card.
Flashing worked (via a standalone Win10 PC).
Installed the GTX680 into the Mac Pro 4,1 (firmware upgraded to a 5,1).
Boot screen popped up just like a new Mac.
Got my Apple 30" Cinema Display and a 23" display - both off DVI ports - running smoothly.
Appreciate the easy steps from post #95 - Thanks @ActionableMango
Now running macOS 10.14.6
My Early-2009 Mac Pro lives another day.

Folks, I wonder can I get some help. I recently got myself a Mac Pro 4,1 that has been upgraded to the 5,1 via the firmware update. It was running a Radeon 5700 just fine and I got the machine updated to High Sierra. I'm now trying to make the hop to Mojave and know I need a metal compatible card. I picked up the EVGA 680 GTX classified card (windows edition) on eBay with the hopes to flash it to a mac card.
I downloaded Dr. Stealth's firmware at the beginning of this thread and flashed in windows. Putting the card in my mac, I see the white screen with apple logo and then the loading bar - about half-way through, it effectively halts and reboots. I cannot get past this nor can I get into recovery (recovery just hangs). I can however get into single-user mode but frankly, can't see anything obviously wrong.
Is there a different rom I should have flashed? Can someone please point me in the right direction?
thanks!

To determine the problem was caused by an incompatible BIOS, try to re-load your original (windows edition) BIOS and use it in Mac, you won't see boot screen but if your card is good, it should load.
If that's the case then it might be due to incompatible (mac) BIOS.
Damn, I knew that ;-) I was just resisting doing it because getting it into my PC to reflash is a royal PITA, but it is the logical next step. I was hoping someone would say 'oh, you forgot (insert silver bullet here)'.
Assuming the bios is bad, does anyone know of one that would suit this card or where I should start digging? I'll do the swap out and reflash this morning so I'll let you guys know in a couple of hours.
So I think I've tracked it down to a power issue. If I take the same card out of the pro and connect it up in a PC with only 6 of the 8 connectors connected (based on the normal 6 pin plug in the mac pro) the PC boots successfully to a black screen.
Doing the same with all 8 connected, card behaves normally. I verified the bios and it is correctly stating the flashed details. So, thinking that for this particular card, I need ALL 8 pins on each connector to be connected, I've ordered 2 6->8 pin cables for a mac pro. I'll get them tomorrow and should be able to retest then.
