How To Flash Gtx 680 For Mac
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. 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. Nvflash -check.

Update successful. 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' so. Does anybody in here got an idea or can tell me how to write the 179kb bios file to the eeprom? Yes it really says successfull.
But nothing changed. Ive compared the files and it is still the 680 bios on it.
The only thing working is reading the actual bios on card. Update: ive read somewhere that installing an empty eeprom can solve this issue.
So i bought some but these chips will arrive anytime this week. Update 2: it looks like nvflash thinks both files are the same. It identifies the card as 1083 which is right.
But windows 8.1 says 1180 and Geforce GTX 680 nvflash -h Zotac.GTX660Ti.2048.120722.rom.

Benchmark Scores Slow. I am using a windows98 dos disk on a 256mb usb memory to boot from in uefi legacy mode (bios) nvflash -protectoff nvflash -4 -5 -6 romfile.rom (i only use the old dos for filesystem. So max 12345678.123) I did try 770 bios on my to get it stable 680. Boost 2.0 did not solved the problem it did however made it not start om on of my motherbords. One p67 two z77. (in main pcie in secondarey it started) I will restart and cheack my version.
I am/was running 5.136 I am a noob here s resoldering resistors? I havent done that sens the geforce2 to quadro. If this is true then maby you can figure it out. =) Does windows drivers dont have the posability like in old times load in updates to the HAL?
Does a fress windows alt linux see the card the same? Just thinking loud. I cant get this baby to work.
Methods i used so far. earse eeprom - wp to gnd on eeprom - ce on gnd by boot on eeprom - flash the original eeprom a several times with original firmware - flashed modified eeprom with different device ids - installed new eeprom - installed card on another pc - checked resistors. changed resistors the only thing left and the only thing i dont know whats next is changing softstraps using nvflash. Im not able to find the strap location. There are locations for older geforce generations on the web but not for kepler. Im giving up. Thanks anyways for your suggestions and help.
