Hello Everyone!
Anyway, sorry for my english.
My video card : EVGA GeForce GTX 550 Ti Superclocked "01G-P3-1557-KR" HINIX Memory.
I'm cut efi_gop from the firmware for gigabyte gtx550ti "GV-N550D5-1GI" Release for SAMSUNG Memory,and compiled using "gopupdater" utility.
I'm Flash a Modded Bios.
Result:
Nvflash --pciblocks

Conclusion gpu-z :
Tests graphics: opengl, opencl function, artifacts are not observed.
Efi gop driver is involved and performs its functions. Obviously it is physically and technically possible.
But I would like to receive from you the original EVGA UEFI. ; )
Anyway, do you have a UEFI firmware for this card?
