GTX 560-448 flash to use in cMP 4.1

Hello friends,

I need a bit of help or ideally, guidance.

I have a PC GTX 560-448 card and cannot find any info in how to flash this to be Mac friendly.

I know of macvidcards services, but I can't justify paying almost 100 for flashing an old card.
Besides, learning something new is not bad either.

Thanks!

This is not a simple task.
You will need to de-solder and re-solder a larger eeprom, from what i understand only certain ones work.

Then theres the fact you have to merge an existing Mac EFI from a q4000 mac into the 560 rom and it its not a cut and paste job.

theres a reason you pay 90us for it. Its not an hours work.
