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

There has been some discussion here in regard to SMBIOS macpro1,1 vs iMac19,1.

I benchmarked my GPU using Luxmark on a iMac19,1 build using the mini guide. It comes in around the 17000 mark.

I would be interested to see what others have out there.

Hope this is okay to post in this forum as it is particular to Casey's build.

iMac 19,1 with RX480, luxmark 14000. This is with a bunch of other stuff open, casual testing.
RX480 in x8 slot BTW, my giant Noctua cooler blocks 16x slot 1.
 
Update on my end - Just got the new Radeon VII card installed. Swapped back to original Clover Config file, dual monitor (dual DP) - and everything seems to be working incredibly smoothly so far. For kicks, I ran a Luxmark benchmark on it, and hit 50.1k, so it seems to be working.

Hopefully - this will be more stable than my old card. I'll report back in a few days and share the results *fingers crossed*
 
Hi @HH007,

That looks exactly like mine, which is running fine. You didn't post a screenshot of your ACPI/Patched folder but you do need to add the SSDT for NVRAM as well if you haven't done that already.

There is no need to restore an image at all. Just create a bootable USB drive with a copy of your normal EFI contents, then tinker with that by copying the new kexts, efi, aml files etc. Just press F12 at boot time and select the USB drive. If it doesn't work then just boot from your normal drive and you are back to how you were, when you can tinker some more until you have it working. When all working just copy the EFI from the USB across to your normal boot drive.

Hello Ploddles,

Thank you for responding, see attachment with the content of the patched folder, yes I do have SSD-NVRAM.aml in it.

So you have VirtualSMC.kext + the two other files both in Kexts/Other and /L/E and VirtualSMC.efi in the UEFI folder and that is working for you? Do you mind posting a screenshot of the contents of your /L/E?

The boot stops with the message HID: Legacy shim 2. CSM support in BIOS is disabled, I enabled that for testing but at the time that didn't make a difference. Do you have CSM support enabled?

I don't know tinker, I just googled it and downloaded it. Where can I find more info on how to use it in the way you just wrote to me? So after I created a bootable usb drive I copy the EFI contents of my Mojave disc to the EFI of this bootable usb drive and then...copy the files of a previously working EFI content? Sorry, newbie in this area.

Best regards

Hi guys, just want to verify something: I don't see my graphics card showing in videoproc, but everything is green. Final cut sees my Vega 64, and I want to ensure maximum rendering performance. I am running imacpro 1,1, hopefully headless: I have disabled igpu in bios, ensured that I have no platform id, inject intel is disabled. I presume all is working well, but just want to verify. About this mac system report shows only the Vega 64. Luxmark benchmark is 65k, 75k with cpu, all looks well to me otherwise.

Sorry for the misunderstanding. By 'tinker' I mean you can just change things on the USB, add or remove files etc.

I am away from home at the moment but tomorrow I will zip my EFI and post it for you to try, I will remove SMBIOS and Serial numbers from my config.plist so just replace them with yours. CSM support is disabled, as per the guide. My BIOS version is F8.

How can the Radeon VII benchmark 2.5 times faster than the rx5700xt? What SMBIOS was that? OS? Was that a dual test including CPU?

Thanks again, ok I understand, actually tinkertool is freeware for the Mac, might be useful at some point ;), fantastic,
thank you for the effort, I'm also on F8.

Best regards

I don't know enough about them to offer an explanation. I'm currently running 19,1 SMBIOS, on Catalina 10.15.4 Beta 1, 2 monitors plugged in, both on DP, and it was the Single GPU only test. I didn't run the CPU or dual test.

I'm not sure I'd say it's 'faster' (and even if so, certainly it's not in every single instance), perhaps it just benchmarks on that particular test better?
