thanks for all you do for the hackintosh community!
yesterday i managed to get on my x58a-ud9 board both gtx480 (zotac) up and running. (with your gfx-string method!)
but: today i started my computer again, and it refuses to recognize the second card again.
as i haven't changed anything, i am now kinda lost. before i tried the gfx-string method i used chameleon rc5 (688 and 700) and graphicsenabler=Yes method. there both cards did sometime show up, and sometimes not.
if both cards showed up, it gave me this strange vram detection: gtx 480 -4095MB NV1ff ...
and boots into black.
so efi string is fine for me, but why it has stopped working? can i change smthing in the bios?
my second card is not broken, i can still boot with either card single...
