Is anyone have displayport hotplug working ? If i disconnect displayport cable from my vega 64 - videocard fan start spins at 100% rate and system freezes.

UPDATE: seems to be a problem with my powerplay through acpi patch injection

I do that all the time, and I've never had those issues.

Good question.. I don't remember.. :lol:

Anyway, as it only concerns the Clover Boot Loader GUI, it can't be vital for the MacOS System performance.. ;)
Yeah, it just displays the word "discrete" at the bottom of the clover screen

Hi Mr.kgp

Do you think i9-9980xe will work?

I hesitate to buy between i9-7980xe and i9-9980xe because the price is a little different.

Step 1, Sell it on eBay
Step 2, Get a Vega 56, or 64 from eBay.

step 3 Rejoice that you don't have to deal with Nvidia's BS anymore :)

What does it help if I think it might work and it doesn’t?

You will have to see it yourself by testing.

If you are willing to delid the i9-7980XE and accept that by doing so you will loose warrenty, I would go for the i9-7980XE anyway.

UEFITool ASUS Splashscreen firmware replacement for ASUS Prime X299 Deluxe BIOS firmware upon 1603 working again

After slightly reducing iMacPro.raw, the ASUS Splashscreen replacement for ASUS Prime X299 Deluxe BIOS firmware upon 1603 by means of UEFI-Tool is working again.

Attached: reduced iMacPro.raw and patched ASUS Prime X299 Deluxe BIOS firmware 1603 with already implemented iMacPro.raw. X299D.CAP to be flashed with EZ Flashback!

Warning! As everybody knows, ASUS BIOS firmware 1603 can destroy the XHCI ACPI table implementation on some motherboards, which likely can be fixed by using boot flag npci=0x2000 in the config.plist. On my system everything works fine but this does not imply that it also works for others.

Thus, this is definitely not a call to move to 1603! This is just to inform that the ASUS Splashscreen replacement now also works for ASUS BIOS firmware upon 1603!

And this is also to inform, that with reduced iMacPro.raw, the ASUS Splashscreen replacement by means of UEFITool might now also work for the firmware of other new ASUS motherboards like the ASUS Prime X299 Deluxe II.

Enjoy and have fun,

@kgp i’ve tried so much now, still kernel panic on boot if my tb3-device is on during boot. If i have it switched off everything is booting up as it should, until i turn it on, then it’s kernel panic as soon as it utilize.

Can i debug the kernel panic in any way?

Anyone else having this issue with Alpine Ridge and Asus Prime X299-A

I guess this is neither a problem of the Alpine Ridge nor a problem with the ASUS Prime but a problem with your specific TB device. I don’t know how to help you further. I already properly implemented the TB-SSDT on your system. TB should now work without major issues. There is absolutely nothing I could to for you in addition.

Good luck, man!
