[Success] AMD RX6000 Series working in macOS

[zabalex]

I think I know what the reason for my GPU problem is. From this page:
https://dortania.github.io/GPU-Buyers-Guide/modern-gpus/amd-gpu.html#navi-21-series

I don't know what Navi 21 series is, but based on the supported cards description from this description, I'm guessing that this is exactly the same card as mine. If so, I have a BigSur 11.2 version. Initial Support was added in 11.4.

Do I understand the description correctly? please, if anyone could clarify this for me, I would greatly appreciate it.

Thank you,

Yes, to get acceleration for your 6800XT, you should upgrade from Big Sur 11.2 to 11.4. This was a pretty big deal at the start of this thread when the Big Navi's were released and people were receiving them but they weren't supported in Big Sur. with each successive update or beta, people were reporting the appearance of drivers but no support. Until finally in 11.4, support was enabled.

Big Sur 11.2 to 11.4

Thank you Tedyun, my guess was correct then.
I have this question, how do I upgrade? Is there somewhere any good step-by-step instructions? The reason I ask is, I just tried upgrading, and spent almost an hour waiting for MacOS in install to 11.6.x, in the end it asked me to re-sign-in with my appleID, went fine. Just so when I clicked on About this Mac, I see my old system in here

I found the guide to upgrade, I guess one of my issues is that I was selecting the backup USB as a loader, do I need to do this?
Also, I'm worried about upgrading OpenCore and accompanying files, is that required?

I don't really know how to do it with 100% certainty to give you a step by step. I have some things I would try, but I've always kept up to date with the software updates. If worse comes to worse, I would make a Time Machine backup of my current system, then install a vanilla Big Sur and perform a restore with Migration Assistant.

OC 0.6.8 should work.

Upgraded successfully, had to remap all USBs.
With 11.6.5, GPU detected immediately without any issues:

Will anyone try 6650 XT or 6950 XT? They seem to be the overclocked 6600 XT and 6900 XT. 6750 XT is the overclocked 6700 XT that we don’t need to consider.

 

[Bustycat]

literally trying now, its showing my ram in megabytes though (6650xt)

Not good to see as AMD will gradually phase out some original xx00 XT GPUs.

?? RAM or VRAM ??
Thanks
Screen capture may be ?

Oh its fixed goot flags pikera for amd and
FF730000 For 6650xt


And BF730000 for 6950xt

This is spoofed though so utilising the hardware through the 6600xt/6950xt lens respectively, im getting around 8 ish% lower reults in geekbench vs windows, sounds about right vs what 6600xt would be!

what is the exact metal score in geek bench 5 ?

I actually did thorough spec analysis and basically anyone that already has a 6900XT that is the variant model, (basically all the super over clocked ones like ultimate red devil) either match even the best 6950 specs or only SLIGHTLY below them. basically AMD just released their own overclocks and gave them a new model number but effectively if you already have an overclocked 6900xt it's literally same card. Heck to even find a 6950 non reference ard that was actually overclocked higher than my 6900, it had to be a water cooled model.

Made me feel better not having latest and greatest...I'm sure these new variants will work with same spoofing we already use for the 6900xt variants.
