Download the latest nightly build for your kexts from here.
Download the latest nightly build for opencore and drivers from here.

Then try it again with the following boot arguments:
-lilubetaall
vsmcgen=1
-disablegfxfirmware

good luck

After some manipulation with opencore its booted and installed.. but, on the last reboot , before apple logo & login screen i have only black screen.

FRESH EFI FOLDER: EFI FILE

i try this EFI LINK, its ready build from another hackintosh from "google search" and booted normaly to desctop without black screens.. i cant undestund what different between my EFI and this EFI makes the second one to boot normal?

I downloaded your GoodEfi.zip and went through it.
I have made some modifications.
This is what I have done:
RebuildAppleMemoryMap = False
SignalAppleOS = True
SyncRuntimePermissions = False

You have 2 kext files for your ethernet, I removed one.
In Tools, I removed everything except OpenShell.efi

BootProtect = none
AppleDebug = True

In boot arguments I have added:
-lilubetaall vsmcgen=1 -disablegfxfirmware

Replace your efi folder with it, and try it.



EDIT:
I also downloaded your Opencore R0.6.0 version of the EFI and made some adjustments to that. Perhaps also try that.

good luck

Bootflags:
-v keepsyms=1 debug=0x100 npci=0x2000 alcid=1 -lilubetaall vsmcgen=1 agdpmod=pikera
(agdpmod=pikera is for Radeon 5000 series)

Also, check your bios settings something is definitely off there.
(check 'Serial Port' and 'CSM' option, both need to be off).
