Hello, I think this is the right forum for this.

I've been trying to get a Sapphire Pulse RX 580 to work in my hackintosh. The system would not POST with the card installed and powered. (I have a thread going on for this issue) I was running GA-B75M-D3P rev1 on the F3 version. Short of swapping out PSU, I thought maybe updating the BIOS would help matters, so I did, to the newest BIOS (F7).

Now, my system loads to Clover, counts down to auto-boot into OSX Mojave, I see the Apple logo (white on black), then the system reboots. I don't know if this is due to not getting the BIOS set up correctly or if there's something now misconfigured in Clover somehow. The new BIOS version is not quite the same, so even though I fairly comprehensively documented my old working BIOS configuration in the F3 version, there are subtle but probably important differences in F7.

I'm hoping someone can help!

Edit 1: To be clear, I am currently trying to get the system up and running again WITHOUT the new card, using onboard graphics. The purpose of the BIOS update was to see if that would help my system POST with the card installed. Currently, I have an updated BIOS (requiring me to re-configure it from scratch) and the system cannot progress much past the Clover boot screen.

Edit 2: I want to be even more clear. Here's the situation:
  1. I had a working Mojave system with integrated graphics (fresh Mojave install)
  2. It functions as a HTPC so I wanted to upgrade to 4K graphics, so I bought what's supposed to be a safe card for Mojave, the Sapphire Pulse RX 580
  3. with the card plugged in and connected to power, the system would not POST. No beeps, no BIOS access, nothing but spinning fans and lit LEDs. (Incidentally, the system would boot normally, with integrated graphics, with GPU card plugged in to PCI-E x16 slot but without the GPU power cable connected). I started a thread in the Hardware Support forum
  4. I tried different things with no success, but noted that my BIOS was 4 versions out of date. Even though none of the documented updates included anything to do with better support for graphics cards, I wanted to just update to rule out the BIOS (had someone else with same board and revision but current BIOS with success with a GPU in High Sierra).
  5. Finally got the BIOS updated (found out along the way that the board does not support Q-Flash even though it's mentioned in the manual), and here I am with a system with a reboot loop after the Clover screen.

My primary goal for this post is to find someone with more comfort and knowledge on BIOS set-up to take a look at my current configuration above and tell me if anything sticks out that would be causing the system not to progress much past the Clover screen.

Secondary goal is to let me know if there are any settings that are not recommended (but not critical to a successful boot).

If it checks out, I'll move on to Mojave support :cool:

thank you!

Boot your system in Verbose Mode and post a picture of your screen when it freezes/hangs.
At Clover Boot Screen press space bar and select Verbose (-v) and Don't reboot on panic (debug=0x100).
 
I have quickly made some changes for you to do - this is just from memory as to what is required to boot. Will check my Gigabyte GA-B75-HD3 settings and respond again in the next 30-60 minutes.

My changes are all marked in BOLD.

Hi BreBo, thank you so much for your response.

I did as you asked - at Clover Boot Screen pressed space bar and attempted to select Verbose and Don't Reboot on panic.

It's strange, as I could add a tick next to Verbose, but after I arrowed down to the Dont Reboot option and ticked it, the tick would stay until I arrowed up once and then disappear. If I arrow back down to the Dont Reboot line, the check mark shows, but disappears gain as soon as I arrow back up. I have video from my phone capturing it, which I'll post if you would like.

Anyway, once I selected Boot MacOS with selected options, the screen goes by fast. I shot a video and took screen grabs, otherwise there'd be no way to capture that without that Don't Reboot option working right for me.

I've uploaded the images. It's just two pages' worth of text, is that normal for Verbose?

Thank you!

Thank you Adrian! I will try those changes out.

Try a different memory fix driver (AptioMemoryFix, OsxAptioFix3Drv or OsxAptioFix2Drv)
If that doesn't do the trick try nickwoodhams.com OsxAptioFix2Drv-free2000

These drivers should not be used simultaneously!

Thanks BreBo. This is something I haven't seen before, but I will look into it.

I do have a couple fundamental questions:
  1. This was a fresh install of OSX. I used Multibeast 11, and of course, the system was booting up fine before I done messed with the gal-derned BIOS. Am I to infer correctly that BIOS updates can result in needing a different memory fix driver?
  2. Before I flex my Google-fu skills, do you know of a good guide I can follow to change the memory fix driver? (and remove the old one)?
  3. Was it that "AMF: Only 119/256 slide values are usable" that alerted you to the memory fix driver issue?
  4. That nickwoodhams.com driver, it says it's for X99 systems - Do I not try that unless all else fails?
Thanks a million!
