Nvidia GeFroce GTX 970 OSX MACPRO 2008 Poor performance... ?!?

1 post in this topic

Recommended Posts

Hi Everyone , I just put my new GTX 970 in my macpro early 2008 today !


 


Everything is working (my 3 screens via DVI (2X) and display port (1X). 


 


I downloaded the latest webdriver and CUDA drivers.


 


BUT , When i run for exemple the cinebench test from MAXON I only have 35 FPS, which is


my previous score with my ATI Radeon 5870 1G memory... I saw a guy making the test on youtube he has 114 FPS !!!


 


I also tested premiere with CUDA but I didn't notice any gain in the workflows or on the effects CUDA is supposed to accelerate.


Same in adobe media Encoder , I did rendering with my old ATI : 25 Minutes and with the new gtx : 24:30 ???


 


Does someone have an idea about that or do I miss something ? I saw some people playing with <key>Kernel Flags</key> 


<string>nvda_drv=1</string> and things like this ??? but I didn't need that for the card to work...


 


Anyway, thank you very much to anyone with help because for now I'm very disappointed with my new GTX .


 


Robin

      Hi guys,
       
      So, this little tutorial is meant to help people fix a new issue with Mojave: opening jpg files (looks like it happens with larger files, not so much with smaller ones) using Quick Look (on spacebar key pressed) or Preview app, using the dedicated GPUs.
      The issue is that, when trying to open jpg files (for some reason, it doesn't occur with pngs), the pop-up window would remain in an endless loop. And from that point forward, any other app trying to open the same file will either become unresponsive (in the case of the Preview app) or just stay in endless loop (in case of Quick Look)
       
      As a workaround, in case the tutorial below doesn't work for you, you can use Grab (built-in app in MacOS) to open said files.
       
      This issue DOES NOT occur using the iGPU. So...if you're comfortable using the iGPU, just switch to that and you should be good to go. You don't need this tutorial.
       
      This tutorial is based on @Cyberdevs' research and testing on this topic (especially useful if you're using an RX series AMD video card), and my own very limited time testing this on my rig. I just thought it would be useful to create a new thread for it so that people can discuss this particular issue here.

       
      With that being said, I'll just move on to the actual tutorial.
       
      New (probably better) method.
       
      Switch your SMBIOS in Clover config in regards to the dedicated GPU you're using, instead of the CPU. Take a look here and choose the corresponding SMBIOS closest to your hardware.
      Yeah, that's it.
       
      In case you lose CPU PM with this method, there are multiple ways to fix that, and they do not make the object of this thread.  It worked perfectly fine for me though and I didn't need to change anything else.
       
      Alternatively, you can also try one of the MacPro SMBIOSes, such as MacPro5,1 or MacPro6,1. It was tested multiple times and it showed good results. 
      Keep in mind that choosing these will most likely not show you an iGPU in System Report, since those machines generally (probably all of them) use Xeon CPUs with no iGPUs either.
       
      A simple Lilu plugin
       
      Thanks to vulgo for the plugin and @Matgen84 for sharing and testing it, we now have yet another possible solution to this issue. It's a Lilu plugin (which means that it requires Lilu.kext in order to work) it's called NoVPAJpeg, and it can be downloaded from here.
      You use it as a regular kext, alongside Lilu. I prefer (and recommend) using it within the EFI folder, in Clover/kexts/Other. But if you want to use it in S/L/E, that should work just fine.
       
      More info can be found in this post here.
       
      In case you wanna try alternative medicine  ...
       
      The main thing we need to do is actually very simple: we need to enable the iGPU (integrated GPU) by default, in BIOS, while actually being connected to the dedicated GPU.
       
      For ATI GPUs (curtesy of @Cyberdevs' post here).
       
      The discreet GPU should be set as primary in BIOS and your displays should be connected to your discreet GPU
      The iGD/iGPU/iGFX must be enabled in BIOS/UEFI as the secondary GPU.
       
      I removed the DSDT Reconfigured the config.plist to and removed some flags which weren't needed because of the DSDT added the InjectATI + Ornioco Framebuffer (I removed the Orinoco framebuffer because of some weird glitches but it might be useful for other AMD GPUs if you inject the correct framebuffer according to your GPU. No need to inject anything for nVidia GPUs unless your GPU needs it) Added the InjectIntel + ig-platform-id for my intel HD530 (for intel HD 530 I use the 0x19120001 ig-platform-id)  
      Steps 5 to 7 might not be necessary I just did them anyway, if anyone succeeded to get quicklook working without those steps let me know so I can exclude those steps.

           Also confirmed to work with AMD R9 270X on a SandyBridge rig (without an iGPU) using WhateverGreen + Lilu kexts, which also helped to solve the transparency issue along with the Quick Look problem, it also resolved the buggy Screen Capture (Command+Shift+5) issue as well. 
       
          Also, do:
      nvram cleanup kextcache & prelinked kernel rebuild reboot  More info on that here.
       
       
      For NVIDIA GPUs
       
      This is what I needed for my NVIDIA rig and the MSI motherboard in the signature. Your milage may vary, depending on your hardware. But, the idea should be the same regardless.
       
         For MSi motherboads (check out my motherboard details in the signature)
       
      Set your BIOS to use PEG (dedicated GPU) so you can boot.
      Since you're reading this, chances are that you're already connected to the dedicated GPU and the BIOS is set to PEG. So just go into BIOS and see if you're using the iGPU or the dedicated (PEG) graphics device by default.
      If you're already using this, skip to Step 3 (the part AFTER Reboot). Reboot (I think you don't necessarily need to boot into the OS...but you do need to reboot at least until Clover UI) Reboot back into BIOS and set it from PEG to IGD (integrated graphics) WITHOUT removing the cable. Save Reboot again.  
         The result should be that the OS is tricked into thinking you're booting with the IGPU when in fact you're using the dedicated GPU.
       
         For Gigabyte motherboards
       
         Set:
      Peripherals -> Initial Display Output -> iGFX Chipset -> Internal Graphics -> Enabled
           DVMT Pre-Allocation -> default 64M.
           DVMT Total Gfx Mem -> default 256M Save Reboot  
         You should do this with the cable connected to the dedicated GPU.
       
      You will also need to patch the iGPU from Clover config.
      1. Graphics -> Inject Intel (UNCHECK Inject Nvidia or ATI if it's checked).
      2. ig-platform-id (in my case for Intel HD 4600 Desktop) it was: 0x0d220003
       
      And use IntelGraphicsFixup.kext (now included into WhateverGreen.kext) in Clover/kexts/Other. In my particular case, without the kext, I would get freezes in Safari.
       
      Another way to activate the iGPU while having the dGPU set as primary is by going into BIOS/SAG/Graphics Configuration/iGPU and setting Multi-Monitor to [Enabled], all the rest remains on [Auto], and set Inject/Intel to [True] in Clover config.*.
       
      Thanks to @gjw for the tip.
       
      *Motherboard dependent. But the multi-monitor option might be the same regardless of manufacturer.
       
       
      This might be a bug with Mojave and it could be fixed by Apple in the future. but in the meantime, feel free to use this if it helps you fix the issue.
       
      For HP motherboards (including laptops), so far no solution, unless the BIOS somehow allows to switch from dGPU to iGPU and vice-versa.
       
      Cheers!

      Salve, vorrei fare un Hackintosh come da titolo, solo che avendo poco budget volevo chiedere se la mia attuale postazione fosse buona e ci fossero componenti compatibili per mac:
      i5 4590
      h97 pro4
      amd r9 280x
      ram 2x4 1600
      alu 620w
       
      Se non erro però la gru non dovrebbe esserlo dato che è amd. Grazie in anticipo

      Buongiorno a tutti,
      E la prima volta che scrivo su questo forum, spero di non sbagliare nulla!
      Scrivo qua sperando che qualcuno di voi possa darmi una grossa mano, perchè ho letto di tutto, visto qualsiasi video possibile, ma non riesco proprio ad uscirne fuori.
      Ci avevo già provato 3 anni fa, ma ero riuscito solo su un notebook Sony, sul fisso non ero riuscito a fare nulla. Dicevano che c'erano problemi con i driver della serie Skylake, così ho voluto riprovare ora a distanza di anni.
      Premetto che non sono un informatico, non ho conoscenze particolari. Sono semplicemente un ragazzo che si informa, legge tutorial ed esegue, quindi chissà che la soluzione non sia in realtà una banale sciocchezza.
       
      Dunque, il problema consiste nel fatto che, in circa 8 ore di prove, non sia ancora riuscito ad andare oltre il caricamento del logo, dopo aver selezionato la chiavetta da clover.
      Sto cercando di installare High Sierra, ho provato con una chiavetta con un programma che non ho capito bene perchè, ma non posso scriverlo qui, e una con Clover Configurator (che tra l'altro, nella schermata boot mi da un'interfaccia diversa da quella che ho visto nel tutorial, o anche solo 3 anni prima), ma il problema è sempre lo stesso: dopo circa metà caricamento, o mi esce il simbolo di divieto, o si riavvia il computer, riportandomi nel boot di clover.
      Ho provato un po' di flags, come -v, -x, -s, -f, nv_disable=1 (tra l'altro, per evitare problemi al principio, ho impostato la scheda video di intel come primaria), cpus=1, dart=0, Slide=0, insomma, qualsiasi cosa leggessi in giro che avesse portato esiti positivi, la provavo
      Ho provato su porte sub 3.0, 2.0 e le 2.0 dietro al pc.
      Penso sia irrilevante, ma nel caso, sto usando una chiavetta da 32 gb.

      Nella firma dovrebbero esserci tutte le specifiche del mio PC, non so se debba postare altro. Nel caso scusatemi, ditemi pure cosa manca che la aggiorno.
      Spero davvero che qualcuno di voi possa aiutarmi. Ho un MacBook Air (High Sierra l'ho scaricato da qui) e ho scoperto quanto sia più affidabile usare Final Cut rispetto a quel bug chiamato Premiére Pro che ho usato per anni, e vorrei poterlo usare anche sul fisso, senza dover acquistare un iMac. Ho letto in giro che con Mojave non è supportata l'accelerazione grafica, per questo vorrei installare High Sierra.

      Grazie mille a chiunque vorrà aiutarmi!

      I'm in the middle of my first hackintosh (High Sierra) on my ZenBook Pro UX501VW-US71 laptop using the Vanilla Install. I've tried using different config.plst files and I've gotten the furthest with RehabMan's own (linked here). It hangs at error message IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0.   Can anyone help me figure out what changes to make to the config.plst file for my specific laptop (which is where I assume the problem lies)   System Specs: Intel Skylake Core i7­-6700HQ 2.6 GHz Quad­core
      Intel® HD Graphics 530 Nvidia GTX 960M 2G 15.6" Touch IPS 4K Ultra­-HD display, 3840 x 2160 resolution   Kexts: AppleALC.kext FakeSMC.kext Lilu.kext USBInjectAll.kext WhateverGreen.kext
