770GTX Black Screen HS. No kexts or anything though

[chicago_mike]

My Intel HD530 is working great. I want to reinstall my 770 though.

So I did, but I get a black screen. Supposedly works OOB , but never quite did. Always had to use AGDP fixup or whatever its called. Should I use that for HS?

Also, nv_disable will freeze HS. So that doesn't work for me. I don't think I have extra kexts for the intel on clover, least I remember. Should I add anything for the 770?

I guess you use SMBIOS from iMac15.1 or 17.1? You can use that but use a Board-ID from iMac14.2 in Clover SMBIOS page. Remove AGDP fixup kext. That will work. I use it that way myself with SMBIOS from iMac15.1 and a Board-ID from iMac14.2.
