AMD Radeon Performance Enhanced SSDT

[xerox24]

I got these panics (using Adobe Lightroom) when I tried the RB kext with VGTab fan control kext (or without).

I have never had panics since I bought my 5700xt, I use weg and bootflag agpdmod = pikera, with ssdt panics, without ssdt no panics, is the framebuffer correct Adder ??? Could it be the cause of the panic?

Which model would you suggest?

Is there a preferred one?

Sapphire Nitro+ 5700 XT seems to be one of the best-reviewed cards. Mine works great in Mac and Windows.

I have occasional panics as well and I have had that same one but only once. The one I am getting with some regularity is:

userspace watchdog timeout: no successful checkins from com.apple.WindowServer in 120 seconds
service: com.apple.logd, total successful checkins since load (6130 seconds ago): 614, last successful checkin: 0 seconds ago
service: com.apple.WindowServer, total successful checkins since load (6100 seconds ago): 598, last successful checkin: 120 seconds agoBacktrace (CPU 2), Frame : Return Address

With that one the computer just freezes and then restarts.

@mattystonnie, what steps should I follow with my rx 470 to get those changes and have my card appear in the PCI section?

@mattystonnie
I really appreciate the fantastic work you've done here.
I run an iMac 17,1 in headless configuration with a Sapphire Vega 64 +Nitro
This is what I did:
1, installed your SSDT.RX Vega 64-Version 2.3.aml in EFI/CLOVER/ACPI/patched folder
2, installed dAGPM.kext in EFI/CLOVER/Kexts/Other folder
Then rebooted and did a Gb5 Metal test, but saw no improvement in performance over previous tests.
So I went back to Clover Configurator/ACPI and moved the SSDT to the top of SortedOrder in my config.plist (see picture)
Then retested and wow! I saw a 30% performance jump in Metal tests! Scores went up to almost 80k from an average of 60k
BruceX Test - 5K.fcpxml down to 10sec from about 20 sec

Thanks again!

Hey! Thankyou! This trick got me +- 5000 more metal points on Geekbench!
My score went to 79126 with a Sapphire Radeon RX 5700 XT Pulse

After some tweaks and overclocking (including this SSDT, v2.3), my GB4 score went up from ~170k to 210k on my (seriously) overclocked Vega 56 (watercooled, custom loop), but only a very slight improve on GB5, from ~59k to ~61k.

Nice!

PS: MacPro7,1 SMBIOS!

Idk something is weird. I tried it now with my vega 56. However, I got a lower number with the patch:
Without: https://browser.geekbench.com/v5/compute/869695
With: https://browser.geekbench.com/v5/compute/869766
With no 2: https://browser.geekbench.com/v5/compute/869785

Random question on this.
I saw this in the release notes for the latest WEG:

"Add support to injecting Force_Load_FalconSMUFW from OpenCore"

What does this mean for this effort? Anything? nothing?
Does it simplify the solution?

 

[slipanot]

what is your luxball score like.. I get over 28000 using the radeonfanfix.kext

Same..
