Looking for Alpine Ridge Testers for SSDT (GC-Alpine preferably)

[NorthAmTransAm]

Hey all, I'm looking for people with z370 or z390 motherboards with an Alpine Ridge Thunderbolt card.

With my Asus Prime z370-A II and ThunderboltEX3-AR I'm abled to get a fully operational Thunderbolt Bus without flashing.

I'd like to try this on a GC-Alpine Ridge card but all others are welcome.

@scottkendall do you have any unmodified cards like this?

No both my cards are modified.

Rats!

Rats!

It is possible to get TB bus on a GC-Alpine ridge without flashing, @CaseySJ was helping people for a while to accomplish this. I never tried because my card was already modified and working in a system that did not have a TB header so I did not want to mess with it.

I think so and was looking to try.

Basically you need to:

1) Find the GPE event that thunderbolt uses. You can find this in your DSDT. Mine is _L6F. You need to do a name change for _L6F to XL6F. If different than _L6F then you need to adjust the SSDT accordingly and make the correct name change to your DSDT.

2) Change RP21._INI to RP21.XINI (assuming its on RP21).

3) This wasn't important in Catalina but is necessary in Big Sur. Remove GPE.TINI. Its more complicated that just find and replace but you get the idea.

Then it's just an SSDT. I'd love to try it on another card/mobo. I don't think its fair its so easy and stable on this combo. Gotta share.

This is one of my masochistic pleasures. It may not always produce the desired results, but in those circumstances where it does work well enough, it's very satisfying.

I see ''no driver loaded'' too, but UA stuff still works. Basically, UA over TB works straight out of the box, you don't need any convoluted TB chip reprogramming to get an Apollo working. Haven't tried all their models(there are just too many) and versions, but I don't see why one would work...

I COMPLETELY forgot about this.

Oh, to add. I remember going painfully over the GPE.TINI patch to fix the boot time issue with using this native solution.

Now, in Big Sur, you can't use this solution without that patch.

I know the 20202020 nature is ugly but its what OC will take and causes not ACPI errors. Clover doesn't require the = lengths.

My hero. I left a detail above for you in an edit. Full sleep, wake behavior now too.
