Does anyone else here with an RX 5700XT experience a behavior that the monitor goes to sleep (black screen) between the Apple logo/progress bar and the desktop login?

-D

Mine does that all the time. Sometime I get worried that it will not boot. Does the same on my other machine with the RX 5600xt.

We can manually set the memory speed to 2933MHz without enabling XMP Profile. There's a pop-up menu with available memory speeds. The highest we should go is 2933MHz on DDR4.

Sorry to reply to such an old post. I'm about to build my hackintosh this week. I thought we were able to go up to 3733MHz now that the new MacBook and 13" MacBook Pro support ram at those speeds. Although I am surprised that the 2020 iMac is still only at 2666MHz. I have Dominator Platinum RGB at 3466HMz and don't mind under-clocking it and tightening up the timings if needed

3733 MHz is with LPDDR4X memory on Intel Ice Lake.

Apple's own Coffee Lake and Comet Lake systems, I believe, are still capped at either 2666 MHz or 2933 MHz.

However, we can definitely enable XMP Profile 1 and use 3200 MHz or 3600 MHz or faster memory. It is only when we experience problems that we should try disabling Profile 1 to see if that solves the problem.

It's lovely, but I hope there will also be a Big Navi version of that.

You and me both!

MacOS installer will take a few moments to load and run.

@CaseySJ all parts are in. Have updated the BIOS to F5. I picked the USB installer and after restart arrived at the OC picker. The Apple and progress bar appeared. The progress bar appears to be stalled. When you write, installer will take a few moments, about how long is a few moments?

We should give it 10-15 minutes.

I restarted and in BIOS under boot there is a new choice for open core in addition to the usb efi choice. I chose that one but seem to be stuck at 50% again
