[Gheorghe1902]

I try this SSDT for imac 19.1 and imac pro 1.1 smbios with RX 5700 XT , Geekbench 5 score rise up from 43k to 73k Metal, and thats all, everything else are left the same, final cut export are the same ,no matter with ssdt or not, i dont understand why we should use this ssdt ? for geekbench score?

Hello guys!
I just followed the guide and I got this results:

BEFORE DSDT:
GEEKBENCH5 openCL: 65695
--------------- METAL: 59653

AFTER:

GEEKBENCH5 openCL: 53519
--------------- METAL: 69039

with geekbench 4 OpenCL: 204177 (couldn't run metal cuz i'm running free version, and didn't tested it with GB4 before doing the guide)

Am I running my 5700xt with full performance?
Comparing with the old XFX rx580 i notice a plug and play performance increase, Like on Unigine Heaven I was only able to get 20/25 fps running on extreme, With 5700xt I'm getting like 60/70 fps same settings. But after doing the DSDT patch from this guide, looks like nothing changed on geekbench.

Was I running full power since always haha ?


PS:I can't get VGA information on HWmonitor and everywhere else with dAGPM. Is there any way to get VGA information like temperature, fans speed etc?


Tks guys, best hackintosh forum ever <3

Is anyone using this on OpenCore with a Dual Boot setup. Ive been using this SSDT and Patch for a while with great performance improvements on my Gigabyte Radeon rx 5700XT 8GB OC. However, I recently made my system a dual boot Windows10 / macOS Catalina setup with OpenCore. I have discovered that with the SSDT-RX 5700 XT-Version 1.0.aml, my system immediately blue screens when I pick Windows10 from the OpenCore picker menu. MacOS is fine and works perfect. If I remove SSDT-RX 5700 XT-Version 1.0.aml and the relevant patch, then my system dual boots into MacOS and Windows from the OpenCore picker menu without any issues. It seems odd that this SSDT is causing this, even after having it amended to include the below. I was hoping there was a solution to this as it worked perfect when I wasn't dual booting my system.

Code:
if ( _OSI ("Darwin"))
{
// do Mac stuff
}

I thought this was going to be useless.. but I decided to give it a try.

I'm using latest macOS Big Sur public beta (20A5354i). I didn't find any difference with LuxMark, but here are the OpenCL and Metal benchmark using latest version of Geekbench 5(.2.3), before and after.
Impressive!

@mattystonnie isn't it possible to use the values from the SSDTs directly as DeviceProperties in OpenCore?

I have something the same directly for the 5700XT and it works like a charm.

But I wan't to learn how to use the SSDT Values as DeviceProperties directly in OC.
Do you have any suggestions?

Hy,
Is there SSDT for Ryzen 5 2400G Vega 11?

@mattystonnie Thanks for this! Is the Patch for find: 50454750 replace : 45475030 when is this necessary? As OpenCore with whatevergreen names this GFX0, seems like this is an EGPU patch?

I got a nice speed boost from this patch!

hi i'm new to this, i have an old pc from 2010 with an intel i5 750 generation lyfield. with an Msi p55-gd65 + motherboard with an 8gb ddr5 AMD shafire Rx 580 GPU, I have noticed that with the video it gives a low performance compared to Windows 10, I managed to enable the graphics acceleration, with bootflag *** shikivga = 32 - shiki-id = Mac-7BA5B2D9E42DDD94. I have noticed that the reproduction of DVDs with vlc is jerky and some emby services give crashes, in Windows 10 it is more fluid ... thanks a lot

Hi all,
I am curious whether this modification is for iMac Headless SMBIOS or iMacPro?
I am using iMac19,1 definition with RX580 Nitro+ in headless mode, anybody has any experience?

@soeryobadja,

The "Performance Enhancement" patches (either as SSDT's or as Injected Properties) only effect the Apple AMD drivers and work on systems that have a Headless IGPU or a dGPU only configuration such as iMacPro1,1. The patches mainly only effect benchmark figures and have little effect on real world Apps, however some users have reported FPS improvements with some games when using the patches.

Cheers
