Yes, but then it will not be upper DVI out?The older GTX 680 firmware will give you the PCI info.
Hi Fl0r!an, Is there any version with PCI info and all outputs running?I've disabled IOReg injection in the ROM you're using, so it behaves like an unflashed GPU in OS X, thus this behavior is normal.
There is, but I didn't publish it due to the reasons mentioned in my original post.
Dear Fl0r!an!There is, but I didn't publish it due to the reasons mentioned in my original post.
Thanks for the reply! By DR Stealth version? In that no upper DVI for my 2x30" CDWhat do you need the PCI info for? It's just cosmetic, the ROM still works fine.
The ROM you're looking for can be build by using the original EFI (not my modified one) and fixing the PC VBIOS (-> DCB spec).
Hi guys
This rom doesn't work for me, I do not get apple boot screen or the startup disk when pressing option during boot.
I am using a screen plugged into the display port on an evga 4gb FTW card.
I have tried both florian and the original rom.
Any further hints?
You provide no troubleshooting information whatsoever, so its kind of hard to say. Are you using the correct version of the utility? The latest version does not work. Are you using the correct command line prompts to override the mismatch? Are you seeing any error messages?
Wow... Cool to see that this thread is still alive after 4 years or so... I haven't been on MR much since getting hit in the head with a trash can. =)
However, I've been working my Mac Pro hard and have had no issues with the dual 680 setup. I'm glad I installed the aux PSU in the drive bay when I did as it seems those 450W 5.25 form factor PSU's are pretty hard to find these days. I recently upgraded my 2010 5,1 cMP with:
Dual x5690's - I was already at dual x5680's but I couldn't resist the rock bottom prices on x5690's
Dual SM951 512GB SSD's
Dual EVGA GTX 1080 TI FTW3's and a GT-120 thrown in for boot screens when needed.
I bounce back and forth between Win 10 and macOS a lot and everything is working flawlessly on both sides and very fast.
Cheers to all !
Can I use this method for Zotac GTX 680 ZT-60101-10P 2GB Graphics Card ?After scouring the web I located a modded rom file for the 4GB version of the card. Its obviously the rom from the 2GB Mac card, same one thats been posted here on Mac Rumors. Version number and date are identical. However its been modified to work with the 4GB card. So I flashed my cards, one at a time to be safe, and low and behold I have my beautiful EFI boot screens back. Didnt really know how much I missed them but so glad to have them back.
At this point theres only one issue. My stock speeds of 1085MHz GPU & 1150MHz Boost have now dropped to 1006MHz GPU & 1059MHz Boost. These are the stock 2GB reference card values. Boooo .
I spent several hours combing through the hex of the rom in an attempt to locate the errant bits. Although familiar with hacking hex its a process that is tedious and can make your head hurt and eyes cross after a few hours. So I took a break and turned to scouring the web again for Nvidia Rom Hacking information. I found on a German web site a wonderful win utility with GUI for editing the clock speeds and several other parameters of the BIOS imbedded in the rom. Kepler BIOS Tweaker v1.25.exe
Heres what I didnt know. Will both the BIOS section and EFI section of the rom need edits to restore my clock speeds? I figure probably yes. This was a Windows utility to edit the BIOS so I thought at best Id have my clock speeds restored in Windows but still have the slower clocks when in OS X.
I did the edit to both cards restoring my clocks to 1085MHz & 1150MHz and wrote the roms back to the cards. Rebooting to windows showed my clocks back to normal. Now booting to OS X was the surprise. The clocks are now back to the higher speeds in OS X as well! So the EFI needs no edit only the BIOS.
These cards are working awesome, full boot screens, full clock speeds & PCI-E 2.0. Just as if you walked in an Apple Store and pulled them off the shelf. (If you could )
Good Stuff..... Enjoy ! ROM and utilities attached below for the adventurous.
The rom is just as I found it with reference card speeds. But you can tweak it with the included utilities.
That is reference Zotac 680, so you should use official EVGA 2GB Mac ROM for flashing - look at @ActionableMango's signature in post #515 on thins page for further info.Can I use this method for Zotac GTX 680 ZT-60101-10P 2GB Graphics Card ?
Okay..... All the standard disclaimers apply. Don't cry to me if anything goes wrong.
1. Download- nvflash_windows_5.134.0.1 - Kepler BIOS Tweaker v1.25 - GTX680-4GB-ROM - Links above.
2. Unzip contents of Nvflash to folder.
3. Unzip GTX680-4GB-ROM and put it in the same folder.
4. Unzip Kepler BIOS Tweaker and put it in the same folder.
5. Folder should now look like this.
*************** Important ! SAVE your Original BIOS file ! ********************************
6. Start Kepler BIOS Tweaker and use "ReadBIOS" button to read the PC rom image from your card!
7. Click "Save BIOS As" button to save your Original PC rom image to your computer!
***********************************************************************************************
8. Use "Open BIOS" button to open the Mac rom image. GTX680-4GB-ROM.rom
9. It should look exactly like this.
10. Now press the "FlashBIOS" button. A command prompt window (nvflash) will open and flash your rom. If it asks you to continue click Y. Wait for it to finish ! Takes maybe 30 seconds.
11. You're finished, re-boot to OS X or Windows to verify all is well.
