Thank you, it seems I may have to upgrade to sequoia as that is the version recommended here: “[WX4130] confirmed card works solidly on Sequoia using OCLP!
All other working AMD cards seems to require soldering mods etc depending on Card model / version and iMac model. wx4130 bypasses these more difficult combinations for now.
EG1.2 ( link ) version ( link ) is better than one directed by post #1 Non EG1.2 vBIOS had random hangs on Sonoma (tested with 2 cards on 2 12,2) Avoid EG2 version unless you plan to flash the logic board ROM.”
It says I may have to flash the logic board rom, how would I do this and is it necessary?
I also have the wx4150, not the wx4130. But it would still mean my card would work with sequoia if the wx4130 works because they are similar, no?
