Nice. But.. how?.

I've got a mac pro 3.1, osx 1.8.4 and a GTX 670. It works, but I think not fully.



Regards!

Where did you get the card?

If it is EFI, they did it wrong.

If it is unflashed, you have a software issue.

GTX670 hack

Hello Rominator, did you finally had succes to get the full pci speed?
If you can PM me how much a solder will cost please?

Also if I can just hack my current GK104.rom bios of 96Kb to get the full PCI speed It'll be fantastic.

Thanks.

I've got an EVGA GTX670 FTW - Have flashed it to the official EVGA UEFI firmware, but still no boot image. How do I go about getting it to work correctly?

The UEFI rom from EVGA is different from the version of EFI Apple uses. In short, you'll have to hack your own rom and probably replace the rom chip on the card. Rominator may have some 670's for sale or offer flashing service for your card, but there's no easy way.

I realise I am reviving an old thread. I have purchased a second hand ASUS GTX 670 2GB which I am planning on using in my first Hackintosh build.

According to ASUS this card has no UEFI support but it can be added with a Firmware update.

Since I have not been able to find a ROM image for this card in order to flash it for Mac boot screen support I am assuming that it cannot be done?

I have looked on this forum and Netkas and there doesn't seem to be anything. The card is probably too old by now anyway but I just wanted to check before I abandon the idea of having a boot screen.

Many thanks

I am not certain how hackintosh functions with boot screen but I would like to clarify EFI.

Macs have used a few different versions of EFI over the years. As far as I know they have never used the UEFI that is now "universal" in PC world. The EFI on our cards meant for Macs would be ignored by a PC, which is what a hackintosh is.

And in fact, some of the mods to the PC Bios can actually cause display issues when used in a PC, so running a Mac EFI card in a Hackintosh would at best get you nothing And might in fact give you problems.

A better question is whether the UEFI on PC Cards can have interaction with how hackintoshs boot. UEFI in Windows world allows faster boots and nicer GUI in the BIOS mod section of pre-boot. It isn't called BIOS anymore as it isn't.

In any case, your questions will find better answers at InsanelyMac or Tonymac
