EVGA GT640 to NVIDIA640

[TerminalStrip]

Hello,
I would like to know if you can put the bios Nvidia GT640 on a card EVGAGT640.
It is not to improve performance but to make the card more compatible with the system OSX (Hackintosh). I tried with NVFLASH but it tells me that the bios is not compatible, there is a way to force the update?
Thank You

Yes you can force it, but there's a reason it stops you. Things might get tough if it doesn't work out. I have flashed an EVGA card to a stock nVidia bios before though.
