To answer the question you edited out - I put 128 for TypeDetail, I think 7 is wrong, because it's "Bit 7" not just '7'. You probably did that already, but just in casethanks!
@TheBloke Did you have any luck getting a 6800XT in the UK? No such luck for me in the States...
No. Most sites didn't even put them on sale as they have received zero stock. The only Buy Button I saw was for a Sapphire Nitro 6800XT at an eye-watering £875 (£275 more than the MSRP for the reference 6800XT) - and even they said no stock until end of December.
I think I'm just going to open and use my 6800. I would have liked the 6800XT, but the reviews indicate it only has about 12-15% extra performance. If it costs 12-15% extra that's fine, but I'm not paying 35+% more for it.
Especially as there might be a chance for overclocking the 6800, and/or flashing the XT BIOS to it. There's work being done on that already, eg on Igors Lab. I don't know whether that would also work in macOS, but it might be possible.
Of course right now we can't even properly use the 6800 cards in macOS. Might have to wait a few more weeks, or even longer, before official acceleration comes. There's some thought that editing an Info.plist or using a Fake ID might enable the card to work with one of the existing kexts, but I don't think anyone has succeeded yet.
