[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

after watching the RTX 30xx launch, damn...... AMD better come up better so we can get that for our Hackintosh!
Or a firmware update for the 5700XT to open up more cores and raytracing :)
I have to watch independent reviews of the RTX 3000-series, but if the RTX 3070 is really faster than the 2080 Ti and costs only US$499, then all I can say is WOW!!
Some thoughts after watching the entire Nvidia RTX 3000-series keynote. First of all, very well done presentation by Jensen Huang (Nvidia CEO).
  • The performance numbers touted by Nvidia ("double triple") might require PCIe 4 (this is my guess).
  • Nvidia RTX IO only makes sense for PCIe 4.0 NVMe SSDs. When the read speed is 7000 MB/s, sending data to the CPU first and then to the GPU is too cumbersome, hence PCIe 4.0 SSDs will send data to the RTX 3000 GPUs directly over PCIe 4.0 bus.
  • When the game data is compressed (which is common) the CPU decompresses it and sends an even larger quantity of uncompressed data to the GPU (the 4th bar in the chart), so the benefit of RTX IO becomes apparent.
  • Remember that only PCIe 4.0 can achieve such high speeds, which is why RTX 3000 supports PCIe 4.0.

But which Intel motherboards and CPUs today support PCIe 4.0?

Even on Z490 Vision D, support for PCIe 4.0 will come later with Rocket Lake and we will need to purchase new CPUs.
  • The only existing widespread platform that can fully support the speeds of RTX 3000-series GPUs is AMD X570 and AMD B550 with Ryzen CPUs (running Windows).
The RTX 3080 will be the first card to ship. It will arrive on September 17. Intel Rocket Lake will not exist. Sure, current Intel motherboards and CPUs can run RTX 3080, but only at PCIe 3.0 speeds.

To exploit the full potential of RTX 3000-series GPUs, PCIe 4.0 is needed. So there is an immediate benefit to AMD!
  • Perhaps this is partially why there was no competitive 'dissing' of AMD in the keynote.
  • Only AMD motherboards and AMD CPUs can fully exploit RTX 3000 at this time.

Hello again Casey,

I have managed to get my partner to take the screenshots for me. I have added 2 additional screenshots just in case you needed them too.
Please post the file: SSDT-RX 5700 XT-Version 1.0.aml

I may need to modify just this one.
 
Because this is happening in both macOS and Windows, and it seems unrelated to the monitor, then the short list of suspects would be:
  • BIOS settings on motherboard (we should start with F7 or Load Optimized Defaults)
  • Some problem with RX 580
What is the make/model of the RX 580?
Does it have a switch to toggle between OC (overclock) and Silent modes?

The video card I have is MSI VGA Graphic Cards RX 580 ARMOR 8G OC, not sure if it has a switch (never needed it).

I've tried
start with F7 or Load Optimized Defaults
, but it didn't yield any positive results. One thing I've noticed is the issue also happens now after I turn on the computer after the complete shut down: LED lights up, fans start to spin, but the display remains dark. After clicking the Reset button on the case everything starts to load normally. Does this indicate what/where the problem could be?

This is a reference post in case you don't remember what the original issue is.
I would really appreciate your help!

Some other questions:
  • Have you tried different HDMI and DisplayPort cables?
  • Have you tried the following:
    • Physically remove the RX 580
    • Connect your monitor (one or both) to the on-board video ports
      • Use USB-C to DisplayPort cable
      • Use HDMI to HDMI cable
    • Then test sleep and wake in Windows (macOS will not output anything over those ports unless we change Platform ID to 0x3E9B0007 and enable HDMI framebuffer patches).
      • Because problem is occurring in Windows as well, first test this setup under Windows.
    • This can tell us if the RX 580 is the culprit.

Hi Casey,

As requested, I have attached the SSDT-RX 5700 XT-Version 1.0.aml from my ACPI Folder.

So do you believe that this may be causing the issue?

At this time I don't suspect the SSDT, but if you post your DSDT.aml I can take a look at both the Thunderbolt SSDT and the System DSDT. The System DSDT is available from MaciASL --> File --> New from ACPI --> DSDT.
Hi - thats good of you - my system runs with a number of ssdts addressing different things. do i create one dsdt for each?
 
sorting out a new issue I came across the Extensions tab in system report and took a look at the extensions relating to Apple Thunderbolt. Im curious to know if this mirrors other users with a Titan Ridge flashed card in a non TB header MB or if I have extensions off that should be on.....
Yours looks very similar to mine.

Please try replacing that SSDT with the attached version.

It may be necessary to make similar changes to other SSDTs, but let's try this single revision first.

There is only one DSDT. Simply do the following to open it, then save it in either .aml or .dsl format and upload.

@CaseySJ Hi - Ok - Just opened Mac Asl....Didnt load an ssdt but it came up with system ssdt. not sure if its right but exported the enclosed DSDT.
