Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

Yeah, that was where it was initially, I moved it to the top slot to see if it made any difference but sadly no change.

So the summary is as follows?

Case 1:

• Long Slot 1: GPU
• Long Slot 2: Empty
• Long Slot 3: Empty
• Result: GPU operates at x8 instead of x16

Case 2:

• Long Slot 1: Empty
• Long Slot 2: GPU
• Long Slot 3: Empty
• Result: GPU operates at x4 instead of x8

Have you tried setting PCIe Bifurcation Support to x16/0 for Case 1, and x8/x8 for Case 2?

That sums it up yes. For Case 1, PCIE Bifurcation Support was set to Auto. I didn’t change it when it slot 2. I guess that’s something I can try.

Please try that; it may be necessary to report this to Gigabyte. Feel free to copy-and-paste the two Cases when describing the problem to them. It's always good to describe these problems clearly and in a structured manner. Bullet lists help a lot. Tech Support personnel have to reply to hundreds if not thousands of requests, so the fewer words you use and the more succinctly you describe the problem, the better.

P.S. This applies to me as well. I *much* prefer going through concise bullet lists. I don't have the time to read big paragraphs.

I’ve been in touch with Gigabyte about it, they have suggested getting in touch with the retailer to RMA or see if they can test the system directly (whatever that means).

Re the bullet points; noted
Thanks very much for all your help so far.

Hi,

A question about sleeping : my computer seemed to wake at first glance a bit randomly from sleep, but it appears it is not quite random, as it awakes everytime any appliance is plugged in, powered on (and I do not speak of usb or anything plugged directly to the computer of course).

Even turning the lights on, and those should be quite separate in the power installation of the flat, awakes the computer... (This is a new flat, where I moved in a couple of weeks ago)

I suppose the power installation is very noisy, but still, I do not understand how turning on the lights (<20w total !) or plugging a switched off electric appliance to a power outlet nearby the computer should suffice to awaking it...

The PSU should be a good quality one (BeQuiet Straight Power 750W) and I am quite baffled by this...

Anyway, I guess the solution might be to invest to some filtered power strip... (I had one, but it just died on me... another hint maybe...)

Have you ever seen this ? I couldn't find much googling about it...

Have you checked behavior in Windows as well? I wonder if the PCIe lanes aren't being reliably reported in MacOs, and might not reflect what the system is actually doing...

Thanks for your suggestion! It reports consistently the same across Windows, MacOS, and BIOS, so I think it’s accurate unfortunately!

There goes that idea! Sorry

I tried testing the Fenvi test this without the USB splitter. Connected Fenvi USB directly to MB and got the same results as before. When I disconnected the USB cable, but kept the Fenvi card in the PCIe slot the system successfully went to sleep in Windows and would wake up with USB Keyboard and mouse. In MacOS it goes to sleep, but does not wake up with mouse and keyboard. I have to push the power switch and it restarts, showing the bios screen and then goes to OpenCore picker. I'll try completely removing the Fenvi card to see if that fixes it for MacOS.

Here's the error log that is now popping up.

Where do I find SSDT-GPRW?

Also I noticed it takes around 15-20 seconds longer for the cpu to go to sleep in MacOS than Windows, not sure if this is normal?

Edit: Looks like it's the Fenvi card causing the problem. Sleep and wake work when it's completely uninstalled. Going to return it and try the Youbo one.

Update: The Youbo card fixed the sleep/wake issues I was having in MacOS and Windows. Quick question for everyone, how long does it take for your system to go to sleep? When I set the system to sleep, the monitor almost immediately turns off, but the cpu takes around 30-45 seconds to go to sleep. Not sure if this is normal for a Hackintosh.
