MP 1,1-5,1 2010 Mac pro GPU question

I opened OC settings and couldn't find this.

DirectGopRendering is the name of the quark in OpenCore config.

EnableGopDirect is the name of the efi driver.

Still couldn't find this or anything resembling this in my oclp settings.

wait one second. Is AMD GOP Injection the same thing?

No, AMD GOP injection is to inject the UEFI GOP into the AMD graphic card.

EnableGop(Direct) is to utillise that injected UEFI GOP to display boot screen on cMP.

By default, cMP can only use Mac EFI UGA to display boot screen. It doesn't know what GOP is, or how to use it.

EnableGop(Direct) make the cMP able to utilise GOP.

However, if there is no GOP on the graphic card, then there is nothing EnableGop(Direct) can do. Therefore, for some older graphic card, users need to inject GOP by themselves.

If not there, and you 100% sure that you are running the latest OpenCore, you can add the key into the Output section.
[N.B. GopBurstMode should also set to true whenever possible. I disabled that because I have this function enabled at the firmware level]

NO, you must power the card properly.

No need a powerful PSU, you may tap power from SATA port etc. All aux power pin must be connected. Just to flash it, the card won't draw much power. However, you need to make sure all pins are powered in order to make sure the card can runction normally.

You may even put you Mac right next to the PC, and use your cMP to power the 6800's aux pins.
