I use the 4100kext mod, no Intel inject (I use fake id 0x19120003, and ig 0a206080) no inject ATI.
Do you have an Intel Skylake? These settings should work for it. I've used them on a Mac pro 6.1, 5.1 def, iMac 14.2, 17.1 def and MacBook Pro 9.1.
If you used multibeast to inject HD 530 you may need to make a new config.plist and replace it in EFI partition as well as the backup EFI folder in your main partition.
6.1 config.plist
The 2 cards work only in open CL like the Luxmark benchmark app. Open GL only uses one so Uningine Benchmarks don't increase over using one card. Try this if you want and if it doesn't work you may try injecting intel with it. I've had mixed results injecting intel, sometimes it works and sometimes it doesn't. Also, look into using a SSDT for your CPU and add it to ACPI folder in clover in patched folder. You can find SSDTs ready made in Toleda threads. If you have a i5 6500 here is one.
