    Intel 12th generation Alder Lake / Hybrid CPU

    in Motherboards and CPUs

    Posted · Edited by Cajones
    Fixed Reviewed Hoopsters Post and followed the guide below. My noobness thought somehow that the iGPU would magically get passed through automatically with the latest update.

    Happy for yall's success so far. Unfortunately, I'm having difficulties, not sure what I've done wrong.  Currently, running Linuxserver Plex with container version set to latest and Plex configured to beta.  Plex shows I'm on Version 1.28.2.6106. I've installed Intel GPU TOP & GPU stats. Enabled transcoding in Plex and disabled HDR Tone Mapping.  All transcoding seems to be handled by the CPU right now instead of the iGPU. Literally see 0% gpu activity on gpu stats dashboard. Also CPU is getting pegged out. Any thoughts?

     

    Specs:

    12500, 32gb ram, ASUSTeK COMPUTER INC. PRIME B660-PLUS D4

    The 6.11 builds of Unraid will have the new kernel natively. By then (based on what little I know), I would expect for HW transcoding to be totally working at that point.

    Great news! I've been trucking along with software transcode for a few months now. Just upgraded to symmetrical 1g internet. Ready to start sharing my plex with friends and family.

    @flyize can you please test if Jellyfin is working on your system and not crashing it? Currently I think the ffmpeg version from Plex is the issue...

    I believe this too.  On the chinese forums they have stability with jellyfin.  Have had it since RC4.  And the only thing they did was replicate what was previously discussed in the forum and follow the brief guide I threw togeather on what i did.

    server is never doing nothing. I'm constantly running encoding jobs in the background on 6 cores, other stuff running on the other 6, often transcoding on the GPU on foreground with 4 plex users. Hope I don't jinx it but it doesn't crash.

    Mind providing instructions on what you did exactly? I know it's a pain, but I don't understand why no one can replicate even with similar hardware. 

     

    To me, I think plex is a large culprit as many people seem to have stability with jellyfin.  My server will crash regardless of transcoding as long as igpu is passed through to plex.

    Lack of E-cores and different iGPU... though personally I'd be surprised if it came down to the E-cores, and would actually be potentially much more problematic.

    My 12500 doesn't have e-cores but has the upgraded igpu. 

     

    What's weird is that other owners of the 12400 report lack of stability. I think flyize runs a 12400 if I'm not mistaken.

    Hey everyone,

     

    just following this thread and almost purchased a i5 12600k today to build a new plex/unraid/docker/vm server. 
     

    Im assuming the igpu issue is still present, is it close to being fixed or should I still use my i7 8700? 
     

    thanks!

     

    I don't think anyone can officially answer that question of when it would get fixed except limetech. My recommendation would be to hold what you have for a bit longer until support is improved.

    11th Gen Intel HW Transcoding status

    Missing a word

    I have a 12500, which shares same family of iGPU. I regret going alderlake right now as the linux kernel support is quite poor especially with respect to Passing through igpu. Doing so causes server instability in 6.10 rc4.  Maybe 11th gen is different; however, I'd recommend holding tight for now if hw transcoding is your motivators. Ones unraid updates to a supported linux kernel, then you might should reconsider. 

     

    Really haven't seen many benchmarks comparing to two iGPU families anyway with respect to transcoding. I'd be curious to know what the difference is.

    My update: as expected, minimal stability using 12500 with hardware transcoding. Server would randomly lock up. 

     

    Pulled the igpu out of plex for now.

     

    Major bummer, hopefully we get some added support in the near future. Really don't want to have a dedicated gpu, but might have to get one. 

     

    12500 is able keep up with a few streams, but not many.

    So I had my first crash this morning, just short of 48 hour uptime.  I was playing around with the 4k transcoding and HDR: the 4k transcode was not working at all (not sure if it was file or server, i suspect server). The HDR content is what I believe led to crash.   Something I noticed before the server locked up was that my iGPU was pegged at ~7 Watts but not actually "doing" anything and wouldn't stop drawing until the server locked up.

    Just curious, what is your uptime?

    I can't really give you an accurate answer to your question right now. I can say that I haven't had any server crashes and ran the server for 3 days without issue.  I took it down this morning to configure and install a new UPS.  If I get any crashes or anything I'll follow up. Right now it seems very stable and I don't plan on taking the server offline again.

    Hi first post here - not sure this is the best place but figure it might help someone else out as this thread is what saved me with my first Unraid build.  

     

    I just recently built my new Unraid media server with an 12th Gen Intel 12500 and was able to successfully get hardware transcoding (QuickSync) to work.  To provide a step by step guide for noobs likemyself who might be struggling - this is what I did:

     

    1. Enabled iGPU in bios (I have a Asus B660 Plus-D4 and the iGPU was actually disabled by default. 
    2. Install Unraid 6.10 rc4 or latest revision (important to be in 6.10 as 6.9 won't recognize your iGPU on your 12th gen cpu in my experience. Scratched my head on that one for a while before coming across this thread.)
    3. configured all of my media services per the Trash Guides (Ibracorp Atomic moves video). 
      1. I Used the Linuxserver version of the Plex Docker - I read multiple places that it plays nicer with QuickSync Transcoding but did not verify this through experimentation of my own.
    4. Install Intel GPU Top by ich777 
    5. Install and configure gpu statics by b3rs3rk (this adds a gpu usage to your dashboard so you can see if your iGPU is working and also gives you neat info on how bogged down your server is getting)
      1. I rebooted the server at this point, don't know if it's necessary
    6. open a console and input:     echo "blacklist i915" > /boot/config/modprobe.d/i915.conf
      1. reboot again
    7. Following the guide here as reference (a lot of this is copy pasted with a couple steps removed that i didn't use or need): https://forums.unraid.net/topic/77943-guide-plex-hardware-acceleration-using-intel-quick-sync/
      1. in console: cd /dev/dri
      2. in console: ls
      3. you should see something like the below

      4. image.png

      5. in a new terminal window type: chmod -R 777 /dev/dri

    8. Now go back to your dockers and in your Plex Docker setting add /dev/dri as a device - I followed the linked guide verbatum 

    9. Enable transcoding in plex, Again follow the guide (pretty much just click a couple check boxes on the transcode tab in your plex server settings).

    10. test your server to see if it works! Select a video to play, play it and make sure to change the quality:

      1. in plex app on computer: while playing video, click the settings icon > click on the quality> show more >choose one that is different than the original file quality 

      2. click down arrow in top left, then the squigly line in the top right and go to your activity dashboard.  If in the description of the transcode you see (hw) it means you are hardware transcoding

      3. Another way to check is to go to the dashboard on your Unraid server and look at the GPU stats that you previously installed

    11. At this point, I was done. I did not need to do any of the other steps listed in the guide to get the settings to persist.

    Hope this helps someone and doesn't confuse anyone. 

     

    I haven't tried converted any HDR or 4k stuff yet, but Generally my transcodes spike at first to like 25% gpu usage and then drops to nothing.  If someone knows a way to benchmark transcoding performance or anything like that, let me know and I can post the results later for people curious how the 12500 performs.
