I wouldn't call it "successfully", as the card is clearly not flashed. No boot screen, generic type in description.
What is your DeviceID? See picture on where to find it. Assuming your DeviceID is 679a (Sapphire Radeon 7950 3GB) the attached EFI ROM I made from your BIOS should handle it.

Thanks for the reply not tested the new bois because the Mac not with me right now ,am message you get a chance to flash your rom ,am followed the nekas forum instruction,guide me what is my mistake i think need to change the device instead of 697A to 679A

PCI\VEN_1002&DEV_679A&SUBSYS_E207174B&REV_00

Am run the same script as mentioned on netkas forum

./makerom.sh --efifile=7950mac.efi --romfile=efiromheader.rom --originalrom=cardname.rom --devid=697a

My rom version on Macpro was MP51.007F.B03,if the efi flash was success can be able to install mojave with EFI boot screen.

"BIOS" not "bois" 😇

Quite obviously you need to properly adjust the variables when converting the BIOS. But I have already done it for you.
Mojave will run on your Mac.

If I am not mistaken the HDMI driver came in Mojave.

Mojave clean install also has no hdmi & display port signal ,DVI working Perfectly ,can inject kext to work HDMI display,
the screenshot the second line shows driver not installed is that issue of HDMI display .
