Radeon Compatibility Guide - ATI/AMD Graphics Cards

Is it beneficial to use framebuffer (Acre) for RX 560 in clover?

 

[UtterDisbelief]

Thanks for this guide. I followed your instructions. Hope that it works!

I hope so too. Report back when you can.

I didn't add any other framebuffers after the patch so I will be interested in your findings

I can't figure it out for the life of me ....if I boot it with inject ati and rdeinit and remove hdmi cable then I plug it back it s going to 1080p resolution without any possibilities to upscale to 4k at all .
If i boot up with inject ati and rdeinit it goes to no signal.
What s your system definition?

Add this kext to EFI folder, kexts->others. It will unlock bigger resolutions.

Then open terminal and repair with : sudo touch /System/Library/Extensions && sudo kextcache -u /

After reboot, boot with ati inject + radeondeinit and open terminal, use this code: ioreg -lw0 | grep CFG_FB_LIMIT ,send picture with the output.

Is anyone using iMac Pro 1,1 with a Vega card?
Is it helping with idle fan speeds etc?

It didn't do anything for me the iMac Pro Vega card has heat pipes and relies on 2 system fans which is probably why we have the fan issue. The iMac Pro also had the T2 Arm chip that controls temps ( and a few other things) as well so it could also be the reason for fan speeds.

I would think at some point by this spring they'll have this fan speed thing worked out since that's when they plan on having good eGPU support (and they'll probably eventually push people to buy the vega cards instead of the current RX 580s). I hope it is sorted out sooner than spring though. I'd like to buy a vega card. The only thing keeping me from getting one is the fan speed issue and the fact that they aren't available anywhere for a regular price. LOL

Okay, so I played around with it a bit. Here's what I get with Lilu and Whatevergreen kexts:



Here's what I get with Radeon De Int enabled in Clover (with no Lilu or Whatevergreen):

I am not sure which one of these is better. I haven't tried sleep yet, just booted up.

Update:
1) RadeonDeInt gives me 83fps in Cinebench. WhateverGreen&Lilu gives me 90fps.
2) System did not boot without RadeonDeInt, had to rebuild cache.

3) The method recommended by UtterDisbelief works perfect. I placed WhateverGreen&Lilu into Library/Extensions and patched via Clover. Thanks again!
4) I have framebuffer (Acre) selected in Clover. I would appreciate if somebody could tell me if this actually does anything.

High End Graphics Card Reach Insane Price Levels: NVIDIA’s GTX 1080 Ti Going For $1599 and AMD’s Vega 64 For $2099[/B]

Let's hope they become more available and the price drops. I got mine for $499 in August.

Did you boot with inject ati and radeondeninit? Yes, I modified only the patch, inject ati, radeondeinit.

Good work

Two things I notice:

1) there is a newer version of Whatevergreen - 1.1.4 available (you have 1.1.3 etc) Not sure if that would make any difference though.

2) you get better FPS than me so maybe the Acre FB is helping. I only use the FP patch I mentioned in my post etc.

As you say, it will be good to get other feedback re the FB.

This is good to know thanks.

I will get a Vega 64 Watercooled and connect the fan to the mobo so I can run it as PWM fan so it would be as loud.
