Flashing A Pc Nvidia Geforce Gt 640 For Mac
The benefit of flash is different depending on brand, model and generation. Most if not all nVidia PC cards will work in a Mac Pro w/o the need for an EFI ROM once the nVidia web drivers are loaded. The issue is that you have no boot screen, and no functional display after each macOS update (because the nVidia web drivers are tied to specific macOS versions). That's why I kept the orginial GT120 next to a GTX970 in my Mac Pro - it was just a matter of swapping the display cable once in a while. No big deal really.
My understanding is that the recent nVidia cards (post GTX680) need some h/w tweaking before being able to be flashed with an EFI ROM anyway so I'm not really sure it is worth the hassle. On the AMD front, the recent RX4xx and RX5xx work out of the box with Apple's drivers (in recent versions of macOS). They still don't display the boot screen (as they lack an EFI ROM) but at least OS updates do not break support as the drivers are built-in. I am not sure an EFI ROM exists that can be flashed, the ROM hack that exists is purely to change the card id and make it appear as identical to the one Apple sells in the e-GPU developer kit - mostly a cosmetic thing, and possibly irrelevant once 10.13.4 is released (the beta seems to properly recognise different AMD PC cards). Things are different with older R9 280x and 79xx cards which can be flashed with the ROM of the latest official Mac ATI/AMD card, and be fully supported included boot screen.

HOWEVER, 1060 may have output issues after flashing. Therefore, even MVC doesn't provide this card's flashing service (yet).

So, practically, the answer is NO at this moment. Also, for your info, the 7950's flickering issue can be avoided by locking the VRAM clock speed (native setting is 1250MHz).
You can do it by editing the VBIOS. Or plug in a second monitor (or even connect the same monitor twice to the graphic card, and then choose mirror mode). Or use some virtual monitor HDMI dongle (which make the graphic card believe it's connected to a monitor) Any method that effectively lock the VRAM clock speed can completely fix the flickering.
Hi, and thanks for the fast reply! I have read your tutorial, which is great and very understandable, but I can not get hold off the HexMiner. It is absent at App Store in Sweden. And I can't seem to get it on the Net either. So I downloaded iHex and payed 5 dollars.
But it does not look as the fine image you provided. I am a Oral and Maxillofacial Surgeon with a great interest in computers but this leaves me with a big uncertainty, when the screen does not correspond. I do read and can follow instructions. This might not be for me. And by the way. I read that the file should be 128K (which it is in Windows 10) but when I drag it over to the Mac it turns out to be 131K.
But still, thanks h9826790! Best regards /Per. Hi, and thanks for the fast reply! I have read your tutorial, which is great and very understandable, but I can not get hold off the HexMiner. It is absent at App Store in Sweden.
