Hi there,

I'm running a hackintosh Monterey 12.1 on Gigabyte Aorus Master z390, i9900k and RX 5700 XT.
Windows 11 is installed on a second internal SSD.
Booting is done by OpenCore 0.7.5.

So far everything is super-stable and all features I need are working fine.

Just for the gaming on the Windows side of things, I could imagine spending the money for a Radeon 6800XT while I can still sell the 5700XT for a reasonable price.

I understand with Monterey 12.1 the newer Radeon cards, like the 6800XT are fully supported?
Can I just swap the card and everything will be fine, or are there any special things (attributes of the card itself, or boot parameters like "pikera", etc.) to watch out for?

Any pointers would be much appreciated.

Cheers,

John

12.1 adds support for RX 6600 but does not take off anything.
Replacing a Navi GPU (5700 XT) by a supported Big Navi (6800 XT) GPU should be drop-in. Same boot-arg agdpmod=pikera still required.

Indeed it was a simple swap of the 5700xt and the 6800xt and no problems were encountered.
There was a little bit confusion about the resizable bar BIOS setting, but OpenCore has settings for this since 0.7.5.
All good now!

What brand did you end up buying? Also, any suggestions on where to purchase one without paying a massive markup?

I got this one:

MSI RX 6800 XT Gaming Z Trio 16G

It did cost a shocking amount of money, but the “old“ 5700XT is currently being sold on ebay and will re-finance about 50% of the purchase.
