EnableGop only works with early-2009 and newer Mac Pros, it's incompatible with an early-2008 Mac Pro.

EnableGop depends on the firmware. It doesn't matter if it is patched into vBIOS or firmware itself, it won't work on MP3,1.

I understand, I thank you @tsialex for your answer and clarify the reason why it would not work
