    Just installed 1.04b and DSM 6.22 (latest, it was automatically downloaded) on an Asrock J4105-ITX

    Worked at first try, thanks!

    The only doubt I have is that after enabling SSH, I checked

     /dev/dri ->Folder does not exist
     cat /usr/syno/etc/codec/activation.conf ->File does not exist.


    I have used the MAC and S/N of a real DS918 btw, but my NIC S/N does not match the one in the config.. maybe this could be the problem?

    you had a previous install on the drive and you didn't format the disk, the boot arguments in dmesg shows DS918 SN?

    So, if I understand well, Plex HW transcoding is working good when setting the bios like you did and kindly explained? 
    I can't get my Q1900-itx to boot headless, so I plugged in permanently an active hdmi to DP adapter and it doesn't cause reboot when transcoding like apollo lake. Did you managed to boot the J4205-itx headless or do you unplug the monitor cable after boot to get HW transcoding without instant crash?

    Both works for me, booting headless or unplug the monitor after you have everything set up. 


    I find it hard to recommend this board, generally I find it hard to get a consistent behavior out if it. currently I have gigabyte 1037u that is working 24/7 for 5 years no problem, this one I'm still testing.

    on J4205 hw transcoding still buffering in Videostation but In Plex seem to work ok . I'm currently checking why transfer rates are inconsistent sometimes.


    With all this said if you need hw transcoding or you try to get as close as possible to the real DS918, DS1019, DS619slim, apollo lake boards are your best bet. Maybe Gigabyte has a better implementation with GA-J3455N-D3H if you can find one.

    I have quit working with Loader 1.04b/DS918+ because of the really annoying performance and swiched back to 1.03b/DS3615xs. Now my geekbench results are 1921 / 3013 compared to poor 956 / 1396 before. Also copy speed to usb ist twice as fast. The last plus for DS918+, the NVMe Cache, didn't work, because my Samsung PM981 was not recognized by DSM (and also not on my Pentium G4400 test system). 


    @x01015918 i have spend some time with different bios settings and found no way to check if cpu boost is working at all. 

    ok.. I will test myself if performance improve on ds3615,

    I tested burst performance like this

    echo "0" > /sys/devices/system/cpu/cpufreq/boost
    dd if=/dev/zero bs=1M count=1024 | md5sum
    echo "1" > /sys/devices/system/cpu/cpufreq/boost
    dd if=/dev/zero bs=1M count=1024 | md5sum


  5. Hi,


    I was trying to test couple module parameters for i915 but they are not picked up if set in the grub.cfg as extra_args.

    I could do it this way but it's not persistent after reboot

    cd /lib/modules
    rmmod i915
    insmod i915.ko modeset=1

    Can anyone help me with a permanent solution?

    Транскогдинг не работает с оригинальным загрузчиком судя по всему из-за наличия на плате J4205-ITX конвертера MCDP2800.

    I will try and update the chip firmware this weekend.

  7. VideoStation experience is bad for me also, but I don't use it. I don't think it's a matter of drivers anymore but codecs. VS is using their proprietary version of ffmpeg and in the older versions could sideload parts of 3rd party ffmpeg functions but no longer. 



    I can transcode 2 4k HEVC simultaneously with plex but VS is buffering on 1 1080p

  8. maybe unrelated, I had issues with cold power up with this board and it got better by removing the bios jumper, asrock j4205-itx supports jumperfree so I see no damage in trying it also.

    I will try and make a detailed explanation with what works for me when I get back from work.

  9. I mentioned "video=eDP:d video=DP-1:d video=HDMI-A-1:d video=HDMI-A-2:d" is not working for me. just remove the cables



    There are three options, I need to set all to "UEFI only"?

    CSM yes all three to UEFI Only


    Don't disable  Intel SpeedStep, it will not burst to 2.6.


    try to keep RAM and Voltage to auto until you make a successful installation


    Suspend to RAM: AUTO; ACPI HPET Table: enable


    get also https://synocommunity.com/package/ffmpeg

    and run ....@appstore/ffmpeg/bin/ffmpeg -config
