Feb 17, 2019 While the 680 and 770 are based on same basic core, by the time the board partners made the 770 they all went in their own direction with components. Most notably the VRAM, fan(s) and power management varied from card to card. In comparison, most 680 cards, expecially the 2GB ones, used similar parts, hence the ability to use the 'Mac rom' on. Apr 19, 2013 Specifically, do you think it'll be possible to combine the EFI portion of the Mac GTX 680 ROM with one from a PC GTX 670? My 670 is a Gainward Phantom with a 183 KB ROM, so the EEPROM should be correct, right? I was able to use the method stickied at the top of this forum to customise a ROM for a Radeon HD 5870. May 30, 2015 hi guys first things first:) this card wasnt mine before. I've made a cheap deal on ebay. Im looking around for a few days till now but i wasnt able to find any working answers. Looks like the prevous owner flashed the bios of a gtx 680 on it. Im trying to repair this little bitch. Aug 28, 2013 The GTX 680 for Mac looks like the best choice for me (being officially approved by Adobe and getting generally great reviews). Unfortunately, Apple seems to be going in a different direction with the 'Pro' line of computers and there's a good chance I won't be getting their 2013 model (it's small and offers no expandability).

first things first
this card wasnt mine before.

im looking around for a few days till now but i wasnt able to find any working answers.

im trying to repair this little bitch.
the probelms...
ive tried every version of nvflash i could find.
none of these seems to work.
nvflash recognized the card as 680 and it recognized the eeprom amic a25L020
im not able to dump the bios successfully.
nothing changed when i flashed the original 660ti bios on it.

it really looks like that nvflash isnt able to successfully write to the eeprom.
the thing i want to try out is program this little bitch with an external programmer.
but i dont understand how since the bios dump is only 179kb and the eeprom has 256kb of space.
another way i was thinking about was to edit the device id.
but i dont know how.
the 660ti is '10DE 1183'
the 680 is '10DE 1180'
Nvidia Geforce Gtx 680 Mac
so... does anybody in here got an idea or can tell me how to write the 179kb bios file to the eeprom ?
