X299 - Open Core support

[mm2margaret]

@Ellybz:

I have an opportunity to pick up a Gigabyte X299 Gaming 7 at a good price. But I wonder if the Radeon VII audio problem will follow me to it from my Prime Deluxe. Do you know of anyone else with that board that might have a Radeon VII? I've looked and I can't find any one.....

It seems like you are generally pleased with your board, is that true?

Are you experiencing scratchy audio with the Radeon VII? You seem to have a rig very similar to mine (Radeon VII, Asus Prime Deluxe, etc). If you ever did experience this audio issue, did you do some method to correct it? Or are you just living with it?

I actually have not tried it. I use DP for my monitors and 3.5mm audio for speakers as well as HDMI out of a Decklink card. I’ll see if I can try it out and let you know.

Oh, really.
OK, use the "SystemProfilerMemoryFixup.kext". It works.

I'm listening to music out of the Radeon VII HDMI to a Denon receiver right now and it sounds great. No scratchy audio at all. My Radeon VII is a Sapphire, specifically this one: https://www.amazon.com/gp/product/B07N3F3QBG/?tag=tonymacx86com-20 I don't know if that would make a difference.

Right, that would work. What doesn't work is if you try to use your monitor speakers (if your monitor has speakers) connected via DP to the Radeon VII. At least so I would bet.....what layout ID are you using in AppleALC for your Radeon VII?

Thanks.

There are so many configs for iMacPro1,1, and they have different Data for SmcBranch / SmcPlatform /SmcRevision

May I know which one is correct ?

Hi guys.
I just finished building my new platform, and I am hoping to boot up with all the previous disk's in place. I have managed to boot into the OS via safe mode and can see that all is in place, such as my raid system, etc.
My old system was based on MSI Z170 mobo with i7 4 core processor. Vega 64 MSI GPU.
The new one is a Asus X299 Deluxe II with i9-9900x 10 core processor. Vega 64 MSI GPU.
I decided to switch over to OC bootloader instead of all Clover. it just makes more sense to me.

Does anyone know if there is some major difference between Deluxe and Deluxe II mobo's? I was wondering if I could use most of the configurations for the original board.

I currently have an issue with the OC is rebooting at the end of the bootloader sequence.

All advice is welcome.
I have a lot of reading to do since I am new to OC an just started reading this thread and others like it.

Update:
I downloaded a EFI here from this thread that gave different results, now the bootloader does not restart the machine but results in a black screen. My guess is that this might be the login screen but cant know for sure. Any ways to tackle the black screen?

Update 2:
BOOM.. fixed it, i found a SSDT for a Vega 64 card and that did the trick
Damn this bootloader is way easier then Clover and much less clutter. Awesome work.
All is running just like it was before. What I find sweet is I had a RAID setup that is showing up as normal even though I swapped mainboard. It's a PCI controller from Startech that has room for two mobile SSD disk inserted that are paired in RAID with two regular HDD. So they get read write speed higher then 300mbs. This is cheeper then buying large SSD disk for video editing.
