Just got the pc version of the gtx 680. Works great. Huge bump to fps in wow under OS X and bf3 under windows comparing to 5870

Now, I want to flush it Mac rom.
Ill follow this post https://forums.macrumors.com/threads/1565735/ but the only card I have that wont need a power cable is gt120. Will this work, or do I need an ati card so that i dont screw up the gt120?
 
If you look at post 170 in that thread, there's a link to a method you can use in bootcamp that doesn't require a second card.

Yea I saw that, but I googled around and found out that people had problems flushing the card with win 7 64 bit
 
I just followed the instructions here, just changing the file names to suit, thus:


To flash the BIOS, download the latest version of nvflash here.
Extract the nvflash files to C:\
Unzip and save the attached Mac Edition BIOS file (gtx68mac.rom) to C:\
open elevated cmd window (hit start button, type "cmd", right click cmd icon, run as administrator)
Change directory to C:\ (type "cd C:\", without the quotes, obviously)
OPTIONAL: type "nvflash --protectoff" then hit enter (turns off any error msg that may result from software write protection)
BACKUP ORIGINAL BIOS: Type "nvflash -b backup.rom" and a copy of your bios will be saved to the nvflash directory
Type "nvflash -4 -5 -6 gtx68mac.rom"
Wait for it to finish
Reboot
OPTIONAL: reinstall drivers

and you did that on windows 7 64 bit right?
 
Yes. I think some people have problems because they try to use the normal cmd, rather than running it as administrator.

If you do a Google search on "nvflash for windows", there are at least 2 versions, 5.134.0.1 and 5.95.0.1. The 5.134 version works in Windows XP, but not the other. It's easy to find out which one works in your OS since you definitely need to back up the current rom file before flashing. BTW, what is the brand and model of your GTX 680? You need to make sure it conforms to the reference design before flashing.

EVGA GeForce GTX 680 | 02G-P4-2680-KR

I'll try using NVFlash 5.134.0.1 for Windows - it comes with 64-bit sys file (i think)

Thanks for helping out:) Just flushed the replacement card, and got the good old gray apple screen at boot:)
