Trouble with new Radeon RX 560 Graphics Card

[db1234]

Hi,

I have Mojave 10.14 installed on the following system:

Gigabyte GA-Z68X-UD3H-B3

i7 2600k SandyBridge CPU

16GB memory

Patriot Torch LE 240SSD

I had the following graphics card:

AMD Radeon HD6870 (GV-R6870C-1GB)

But I wanted to upgrade it to a better performing card, so I just picked up:

Gigabyte AMD Radeon RX 560 4GB

(GV-RX560GAMING OC-4GD

I swapped out the old with the new, but now Mojave is only recognizing RX 560 with 3MB and will not detect my display(s) or the proper resolutions. SwitchResX doesn't offer any options either.

Would anyone know how to update my system correctly to my new GPU?

Thanks in advance!

[ref]db1234[/ref], RX560 is native, is a strange problem

CLOVER.zip

I know. I was trying to purchase a card that was a known working graphics card OOB. Is it maybe because I installed using dosdudes patched installation from an old card and now with the new card it shouldn't need all the patches?

So, the clover file you attached, just replace my other clover folder in the EFI volume and restart?

Not sure how to create a vanilla installer...can you recommend a tutorial vid or link?

Oh, do you mean just use the regular Olarila installer for Mojave? Start over as a new install?

where do I change to iMac13? Selecting 'o' on the installer just takes me to the SMBIOS with s/n, board id, etc...I would not know what to change on this screen. Or am I looking at the wrong area?

just change iMac13,2 and work

[db1234]

I changed product name and board version to 13,2 but now the installer just hangs at a grey screen once those changes are made.

Should I only change product name to 13,2 and leave board version at 12,2?

[ref]db1234[/ref], just change Product Name solve, if don't wrk, try with iMac14,2, but for good PM etc u need a correct smbios

It was a dual monitor issue. I unplugged one of them and the install is going as expected now. Sorry for the additional post/confusion.

It's currently installing. Thanks!

Awesome, everything installed. Now I am just trying to clean up the DSDT.aml.

I have used the RunMe app to generate the attached. Would you be able to assist with the errors and warnings to get a clean DSDT? Trying to make sure it is also set at 13,2 as you suggested above.

Thanks, MaLd0n!!

Thank you so VERY much! I applied the new DSDT, ran RepairPermissions script, and rebooted. The only issue seems to be system report showing this as 12,2 instead of the 13,2 that was used to install Mojave...

Sound works, Video works, DVD codecs work, and I no longer need to use SwitchResX with the new video card. Dual monitors working and showing proper memory. All in all it seems to be a successful install! With your help, which is greatly appreciated!
