I've solved my USB issue with a boot argument : uia_exclude=HS04;HS06;HS09;HS10;HS11;HS12;HS13;HS14;SS01;SS02;SS03;SS04 As I have no Front USB in my case, I keep only the 4 ports USB2/3 rear + the 2 USB ports for mouse/keyboard. Seems to works... I will test an USB-C drive tomorrow. Now I have to figure out the Vega64 fan issue and at least try to have 50.000 in geekbench with my CPU. Actually I have 48.000... Thanks for your help and of course if you want to post your EFI, I will be happy to give you mine too :-) Regards

I've try your SSDT with no luck... I will wait for your full EFI, thanks again, not urgent :-)

OK will try, because we have the exact same motherboard expect that i'm on F1 Bios (I can update of course but last time I've try, the machine refuse to boot OSX). The only difference is that I have a 7960 when you have a 7980. I test and I let you know, thanks again.

Ah yes you are on High Sierra, no sure it will works on Mojave... And I'm in F1 bios. I already try your DSDT, it boot and works but still no USB. Where I'm wrong ?

Hi there, thanks for your reply ! Yes the file was edited correctly, I'm still at 48.000 in geekbench... But I have others problems : No USB3 and no USB port working at all. Can you please share your EFI for the X299 Designare EX ? I will share mine too if you are intrerrested, I'm with Mojave 10.14.2 for now... Regards

Hi there and thanks for your reply ! Yes of course, we tested everything, and the only way to put all cores to 100% is in Geekbench... In Resolve, even with a big 4K session, all cores are at max 35%. Don't know why, I've read that it's about TSC Sync but I don't know how to proceed. I will go ahead and restart from scratch the computer, install Mojave, and we will see.

Hi there, I have a similar setup with Ga-X299-Designare EX and i9 7960X, 128GB Ram, SSD Samsung NVME. The problem is that in Resolve, all the cores are not fully working : I mean when rendering the CPU is working at 35% max (I see that in iStat). I'm with iMac Pro SMBIOS, latest High Sierra 10.13.6, and I've tried this setup with a 1080Ti or a Vega64 and there is no change : Core not fully working. On the real iMac Pro, I tested my Resolve session and the cores go up to 90%... So I don't understand what the problem is. I will try next week to restart from scracth with Mojave and the Vega64 card and I will come back to you.
