also you can use this in your Device Properties section in your config plistobviusly using also Whatevergreen kext and a correct ACPI path for your GPU

i use Hackcheck app or similar to find my path

It doesnt corrupt anything in your systemTo download it ditectly you should have a hello post or two post in italian forum

You have to copy my screenshot and only to change left path with yoursIf you like post tour config and copy paste here paste here your acpi pathbelow how to with a plist editor:

yes it seems fineif you use pikera as bootarg you can skip this in DPi use it in DPremember to use whatevergreen kext

(Zitat von DevFelixJava)Explain what happens?If it doesnt work maybe your PCI address is wrong

i use hack check, but if you like you can also try to use a SSDT like thisYou have to check in IOREG your path and change them accordlyEDITWith DP it should work so i think some errors i cant see by now (sorry)

you have to open and edit with maciasl appand find yours here:

(Zitat von DevFelixJava) https://github.com/acidanthera/MaciASLi use thisEDIT2 DevFelixJava i see you are on AMD as meWhich AMD Kernel patches do you use for FIX pat? algrey or Shanees's ones?Second one is faster in benchmarking gpu

I do not follow dortania guide for this (i use and like their product like OCLP but not their guide for AMD)Default patch used is algrey oneit is much slower than Shanees onei would suggest to try it and if you do not have additional problem i would use Shanee patchI would also check better Device properties and use it togheter whatevergreen kext (disable NootRX kext)you have to use ioregistry explore app and search for GFx0, you will find your path and you have to change in my SSDT here

(Zitat von DevFelixJava) Post your config plist without smbios data and serial (if you like)Dp works well for all our 6950xt so we have to do also for yourattached hackcheck (if you like to try and put acpi path from there

mmmh it is the one i use i cant say if it needs some permissionhowever i see you are using Algrey fix pat patchto improve performance in OpenCL/GL you can disable it and use the Shanees onefor now if you cant do good resuòt with DP or with SSDT you can try also with NootRX kext and see the differencesin Opencl your system should have a result greater than 100000 as you see in my picture abovei have tried to modify your config.plistuse also the kext attached (backup yours first)in this config i u…

(Zitat von DevFelixJava) the only problem could be your <GPU acpi addressothers parameters are the same for all people who use to spoof their GPUEDITi see you have acceleration using NootRX kext but only low performancetry to recreate that condition and only to disable to that config algrey fix pat and enable Shaneee fix patyou would see a great improvment in performance

(Zitat von DevFelixJava)if you like to do latest try, post your actual EFI and execute this app (or one you have like this)https://github.com/vulgo/IOReg…xplorer/releases/tag/v2.1post the results (save as a file (it is your system OSX registry)i would try (if you want) to do a SSDT for you

first trydo a GeekBench GPU test and save the results (metal/Opengl/CL)then use this config.plist (overwriting your after backupping it) an do the same and please post the resultI am preparing your ssdt to not use NootRX kext and see if we had acceleration as all we have

i did what i am saying from my initial post here disabled a patch used the other I woluld like to say you should understand why ACPI method does not workif you can send an IOREG log without using NootRX (i know no acceleration there)i see some bridges i do not underst (i am not an ACPI expert so it is my fault)

DevFelixJava it seems not disabled hereif you can use MacPro7.1 SMBIOS and redo an ioreg log both with NootRX and without it (without it only a monitor on shold be present and obviusly no GPU acceleration)

(Zitat von DevFelixJava)i do not know if NOOTRX needs to use ImacPro 1.1 SmbiosFor your CPU is more appropriate to use MacPro 7.1 Smbiosi would try to use in this way if possibleHappy you solved initial problem but i think is it possible to improve your system configuration

SchmockLord your XTXH has a device id not supported by osx AMD gpu driverSo you have to spoof it to a supported one by this driver6950 xt is not supported in any osxSo we have to spoof to a supported device id from a supported 6900 xt (different but similar to a 6950 xt)Luckily it worksI can use also NootRX but i prefer to spoof and use whatevergreen kext DevFelixJava user has a pci acpi path in his ioreg i cant understand for my limited acpi knoledge and also his pciroot address seems doesnt w…
