    X299 Big Sur Support

    @izo1 The question is: our mobo does or doesn't support MAT tables (complying with the latest EDKII builds). According to reports by Dortania Installation Guide, the solution is the following: If your firmware supports MATs(2018+ firmwares): EnableWriteUnprotector -> False...

    @izo1 I'm running BS release w/o particular problems, only the DP audio of my R7 doesn't work. As I have the same system as yours, can you share your EFI? Do you remember? I made my 1st Catalina OC installation with your EFI last august ... :)

    This is the KP that sometimes occurs...

    Hi, I succeeded to install BS (20B29). All work fine but sometimes I have a reboot reported as a problem with GFX0 kext. That happened with Catalina too and a Google search allowed me to discover that this seems to be an issue related to Radeon VII audio. Studying the KGP posts and his guide...

    Sorry, but I run the "other" (in my EFI) since august, and then yours doesn't seems to be a valid explication

    Thank you for your answer. I attached two versions of SSDT-PLUG: can you tell me the difference between the two? Referring to XOSI one, what is the purpose of simulating a version of windows?

    Who is so nice to explain to me the difference betrween the two SSDT-PLUG attached files? And the function of the attached SSDT-XOSI too? Thank you

    Hi to everyone I was been absent for ages as my job has taken over. I'm already running Catalina 10.15.7/O.C. 0.6.0 and I'd like to begin with Big Sur and I couldn't follow the evolution to the latter. At this time, my build is so composed: 1. ASUS SAGE/10G 2. 128 GB RAM (16x8) 3. Radeon VII...

    Hi to all, I write here although I'm already on Catalina. I tried to upgrade to OC 0.62, but post the reboot my hack hadn't load the Highpoint RAID controller kext. I had to return to my 0.60 EFI and I don't understand what caused this behavior ... Any ideas? Tx

    As this thread is oriented to all x299 motherboard models, I will propose to put together all the know how related to the alternative SSDT/device properties/USB, trying to expand the PDF guide already posted by @Loloflatsix, to let all us capable to better self configure the EFIs ...

    In the Asus software repository, I found any chipset update for Windows (see attacched screenshot). As I run a dual boot system, what appens to my build on the macOS side if I apply these upgrades?

    Another probably stupid question: I run my build with cascade lake 10940x cpu. Should I anyway use TSCAdjustReset.kext? I’m still studying the basys of the OC configuration and I read that this kext was initially written for Skylake X CPUs and so I had the doubt...

    A probably stupid question: I broke one pin of my onboard usb 3.0 header, where is connected the USB 2.0 FENVI Bluetooth cable. Blietooth seems to function but I was wonder if I could use this cable instead ...

    I didn’t understand: I’m already on Catalina. Should I update SSST-PLUG and use SSDT-DMAC?
