  1. Hi, if anyone is interested to fix the boot with vd-t enabled, you can use the following kernel parameters iommu=soft iommu=pt intel_iommu=on
  2. you had a previous install on the drive and you didn't format the disk, the boot arguments in dmesg shows DS918 SN?
  3. SMB read/write speeds improved from 30-70 MB/s to 90-110 MB/s
  4. J4205-ITX DS918+ Jun's Mod V1.04b dd bs=1M count=1k if=/dev/zero of=/dev/null | md5sum d41d8cd98f00b204e9800998ecf8427e - 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 0.164326 s, 6.5 GB/s
  5. hi, don't assume all issue are related, could be just a faulty plex install or upgrade, I prefer in between testing iterations to format the drive just to get a consistent behavior.
  6. 1.80, with specter and meltdown on, should I expect big difference in performance if I disable meltdown?
  7. hi, 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.
  8. 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
  9. I have 1.04b, for is showing the correct temp once is over 40
  10. that is the point changing /sys/module/i915/parameters is not working by grub args, and the insmod i915.ko modeset=1 works only until reboot. this one also is not working root@DS918:/lib/modules# echo "1" > /sys/module/i915/parameters/modeset -ash: /sys/module/i915/parameters/modeset: Permission denied
  11. 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?
  12. if you keep digging on the forums a lot of people complain about the board and most have different heretic behavior, like this guy have even weirder issues on windows, somehow it explains why we notice different behavior with the same boot image or extra
  13. I will try and update the chip firmware this weekend. https://rewster.uk/2017/02/12/asrock-j4205-itx-issues-that-intelasrock-need-to-fix/
  14. try also and update i915 firmware, in my extra I added the latest ones. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915
  15. mine is not rebooting, just buffering every 3-5 sec, I do always keep the display unplugged (that is causing me reboots but also in plex) my point is that if the drivers is loading fine in dmesg, hw trancoding is working in one of the apps the only different thing is the version of the codes VS is using.
  16. 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. https://github.com/SynoCommunity/spksrc/issues/2952#issuecomment-337214013 I can transcode 2 4k HEVC simultaneously with plex but VS is buffering on 1 1080p
  17. Is it properly detecting your cpu? you have boost disabled in bios, not sure how amd calls it.
  18. what is the output for dmidecode -t processor | grep Speed echo "1" | sudo tee /sys/devices/system/cpu/cpufreq/boost ?
  19. 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.
  20. 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 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
