3900X with X570 Master V1.1 . 6800XT Nitro + SE. 16 GB 4400 DDR4

Was a bit of a drama getting it to update , in the end built a new 0.6.8 debug stripped right back and got there.

OpenCL is very slow , but the metal is impressive

That’s strange as I thought the nitro used the same layout as the reference card so the dp port should work fine.
I have tested a hand full of 6800 and 6800xt models and makes and they all worked via dp with weg disabled.
I didn’t try a nitro as we dont have one on the shelve over here.

Strange , but all is working , faster on CL and a little slower on Metal according to geekbench

Swap the last two patches. Disable Algrey’s PAT patch and enable mine. It’ll increase GPU performance but HDMI/DP audio will suffer.

It must be the apple drivers as using windows I get 173566 under CL . But using that patch on Big sur I get as high as 191000 on Metal.
So its really good . Will have to see when I add water cooling to the Nitro +

Under Windows, I got 180,000 in OpenCL, and under Bigsur, I also got 190,000 in Metal, but only 110,000 in OpenCL

Used a different config. The graphics have started. But now there is another problem. The installer loads data on the ssd and when booting from ssd the kernel does not start when choosing to boot from this ssd, as I understand it ... I do not understand why.
