i7-4930K - Asus Rampage IV Extreme - 32GB RAM - GTX 770 4GB [Success!!]

Hello all! First off, let me say this is a wonderful guide and I appreciate all the work that went into this!

I would love some help with troubleshooting. I have a friend who has the Rampage IV Extreme Motherboard on the newest BIOS. We followed this guide to the "T" when upgrading him to Seirra (10.12.6). Everything is working quite well except for his graphics card. He has an Nvidia EVGA GTX 1080 Ti. The computer has no trouble with Multi Monitor DVI resolution at 1080. However, he owns two SW27i BenQ monitors. The max resolution on both those monitors are 4K. The computer will boot great with one in the display port, and the other unplugged. Then once he is past the login screen, he can connect the other one into another display port. If he doesn't follow this technique, the monitors are not recognized and his computer falls into the "black screen" issue discussed in this thread. The only way to get it working again is to reset the NVRAM in single user mode. We've tried installing the NVDIA fix app included in the post files. Unfortunately, this has had no effect.

Is this an issue with NVRAM not working properly? Has anyone else had this issue?

Any help is extremely appreciated. :)

Hi, @shilohh!
Long time lurker´s first post...
So, I've been following this guide and successfully installed Sierra 10.12.6 on my system(yey!! Thank you:headbang:), but couldn't make SpeedStep work.
I've tried everything, every guide, I've extracted my own SSDT. Followed the guide to the T.
My CPU stays idle @1.2MHz and I'm starting to feel desperate. There is no way this thing is working.
Geekbench gives me 1293-6668
Can someone help me please? I can provide any info and files required.
Thank you in advance.

Mojave anyone?

If anyone has done the upgrade, have you stumbled on to any problems?
Found any solutions if so?
I have update to Mojave without problem with my build ( R4E +i7-4930+ ASUS RX 580 + 16GB corsair). I use the X79 liked in this good guide. I was looking for an optimization of the conf.plist for patch 10.12 of conf.plist present on this guide

PS. toleda script for audio not work with Mojave for this i use the guide present on Mojave desktop support for ability audio on Mojave.

my Rampage IVE board fizzled out decided not to boot anymore not sure why, was perfect under your guide, now I have a Chines unbranded X79 board seems to be close to it at fraction of price ,runs Yosemite out of box like R4E.Had issue with boot up with HighSierra had to edit I deleted Device(SCK0) to Device(SCK3)
Finally after modifying, all Processor locate directly inside _SB instead of _SB.SCKN.
Hope you guys with X79 motherboard can solve this problem .Now I cannot shutdown it only reboots.Not sure where it is the point to cause this ,maybe my usb edits I used clover to change EHC1 to ENC01 45484331 in clover there is drop down with total of 4 edits I selected all, 4th was USBE to EH02 in list of patches. along with injectALL kext solved my usb problems.
everything seems ok have not tried Sleep but no biggie Just would like it to shut down. I wanted to try SSDT edits but not sure
where to edit.I played with ticking SSDT settlings in clover at no avail.

Hello! I use i7-3960x +R4E! According to your tutorial Settings, the machine works fine! But there is a legacy issue Cannot overpass frequency, can only switch back and forth between 1200M-3300M! Is there any way to correct it?
I've tried regenerating the SSDT from your tutorial, but the effect is the same: you can't overdrive or multiscale.
Now I upload my efi file, please check it for me!
Here is my boot.log file!

OK!I solved!

Hi again everyone!

After playing with "Dark Mode" on my MacBook, I became addicted. So I am testing 10.14 Mojave using a separate SSD drive on my trusty old 3930k Hackintosh.

It went pretty well so far. What I did:
1) Since I have been on 10.12, and there is no way to get APFS support, I decided to install from my MacBook. I booted the MacBook up in recovery mode and connected the new SSD externally in a USB-3 enclosure. I formatted the disk using GUID and APFS. Then I installed 10.14. I went ahead and set up a user on first boot (still running on the MacBook).
2) I downloaded the newest Clover and installed on the external USB drive.
NOTE: Above steps could be done the usual way with a USB stick that has the apfs.efi installed; but I was lazy and had the MacBook handy.
FIX UP CLOVER - copying files from my old working 10.12 clover EFI
3) I mounted the EFI partition using "EFI Mounter V3" app and copied all the kexts from /EFI/Clover/kexts/10.12 to /EFI/Clover/kexts/10.14 (AppleIntelE1000e.kext, FakeSMC.kext, and realtekALC.kext).
4) I copied missing drivers:
apfs.efi <- downloaded the appropriate 10.14 version of this
5) I copied missing config files:
6) At the Clover screen I booted with nv_disable=1 and also -v
7) Once booted up in low resolution, I ran shilohh's trusty AGDPfix and rebooted.

Now I am running my dual displays at full resolution with Metal support in Mojave! It has actually been very stable! Next I need to fix my audio and SpeedStep.

I didn't have any luck using the newest version of the audio script from shilohh's guide. It runs but I have no audio.

Now I have to figure out how to get the very basic SpeedStep I use running (I'm basically running 4.2Ghz without much stepping). At the moment I seem to be locked at 3.2Ghz on all cores. Unfortunately I cannot use the full power management setup shiloh uses because my particular 3930k CPU causes crashes when the speed/voltage drops too far...but is 100% stable as long as that never happens. Oh well, at least I can switch back to full speed 10.12 at any time by just swapping SSD drives.

I have been messing around with creating SSDT files; but am pretty rusty. I included my EFI partition ( in case anyone wants to look it over.

This won't be my main system until I can figure out these issues; but it's cool to try!

Hello guys
I have one question to you: I have the configuration (R4E + i7 4930 + GTX1080) that upgraded to HS recently - and sleep stopped to work (or works partially: screen goes black but motherboard/fans are still power on). Does anyone with sleep working could share config or pointing me where to debug this problem?

Regards and TIA
