  1. Test stand: ASRock J4105-ITX, Crucial DDR4 so-DIMM RAM with 2400MHz CL17-CT4G4SFS824A 4GB, flash drive, 2.5 250GB hard drive. Prepared the flash drive as described here, installed the memory, connected the HDD and turned on the power. It worked without the BIOS reconfiguration. Power consumption 10 watts, the folder /dev/dri is in place, installed the Video station, the codecs was activated. With transcoding 4K here is what I got: On four streams of transcoding consumption increased to 30 watts, the CPU radiator is noticeably hot, so who plans to use xpen in this mode-think about a good blowing the radiator. Installed VMM, ubuntu and virtual DSM worked fine, but it is better to add up to 8 GB of memory.
  2. Hi, I removed the faulty i915 drivers from extra, you can download and test it here. hw transcoding is working but performance is low on both videostation and plex but I don't think is related to the loader. on ASRock j4205-ITX you have to unplug any monitor before using hw transcoding otherwise the system will reboot, this one might be due to /dev/dri permissions or the DP to hdmi coverter on this board. reboot/shutdown is working properly again. I recommend doing a clean install, formatting the hard drive before testing. You can test disabling video outputs in the grub, for me it didn't install properly. video=eDP:d video=DP-1:d video=HDMI-A-1:d video=HDMI-A-2:d root@DS918:~# ls /dev/dri card0 controlD64 renderD128 root@DS918:~# cat /sys/kernel/debug/dri/0/i915_frequency_info PM IER=0x00000070 IMR=0xffffff8f ISR=0x00000000 IIR=0x00000000, MASK=0x00003fae pm_intr_keep: 0x80000000 GT_PERF_STATUS: 0x006030cb Render p-state ratio: 48 Render p-state VID: 203 Render p-state limit: 0 RPSTAT1: 0x12000030 RPMODECTL: 0x00000d92 RPINCLIMIT: 0x000027d8 RPDECLIMIT: 0x00005a00 RPNSWREQ: 800MHz CAGF: 600MHz RP CUR UP EI: 3192 (2660us) RP CUR UP: 477 (397us) RP PREV UP: 0 (0us) Up threshold: 85% RP CUR DOWN EI: 5109 (4257us) RP CUR DOWN: 482 (401us) RP PREV DOWN: 0 (0us) Down threshold: 60% Lowest (RPN) frequency: 100MHz Nominal (RP1) frequency: 250MHz Max non-overclocked (RP0) frequency: 800MHz Max overclocked frequency: 800MHz Current freq: 800 MHz Actual freq: 600 MHz Idle freq: 100 MHz Min freq: 100 MHz Boost freq: 800 MHz Max freq: 800 MHz efficient (RPe) frequency: 250 MHz Current CD clock frequency: 624000 kHz Max CD clock frequency: 624000 kHz Max pixel clock frequency: 624000 kHz [ 127.551937] ACPI: Power Button [PWRB] [ 127.601681] Linux agpgart interface v0.103 [ 127.674041] [drm] Initialized drm 1.1.0 20060810 [ 127.809306] [drm] Memory usable by graphics device = 4096M [ 127.882071] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

  3. So I had DSM 6.1 running in a 3617 loader v1.02 on a Dell T300 baremetal tower. I used the video station package to host my library. Transcoding worked with video station as in I could select playback quality "low" in the video player on either DS Video apps or the web interface and DSM would transcode on the fly and stream me a low quality version of the film or tv show. I can't say for certain but I am pretty sure this was software transcoding since I didn't have a GPU in the machine and I wasn't running the 916 loader. Now.... I have recently switched to a virtual environment with ESXi and have successfully gotten DSM 6.2 running on a 3615 1.03 loader VM. Video station works, but the above transcoding situation does NOT. When I click a different quality besides original, it stops the video, and has a loading wheel that never finishes. If I change back to original, the video plays again. For the life of me, I cannot figure out why.... I am running ESXi on an R720xd with E5-2630v2 CPU which I'm pretty sure is newer than the T300's CPU... Anyone have any ideas where I can begin to debug or fix this issue? I am not even looking for true hardware transcoding, just transcoding to work like it did on the older T300....

    Plex Server

    can anyone tell me the downsides of having a separate mini PC (i.e. intel nuc) to front as the plex server instead of using the DSM? my current setup is an asrock J1900DC-ITX in a fractal design node with 5 HDs (4 using onboard SATA, 1 using a iocreate SATA pci card). my DSM is ds3617xs on 6.2. the DSM is currently my plex server. if i buy a NUC J3455 (or J5005), install windows 10 home, install the latest plex server and add movies/TV media from the DSM, i can expect hw transcoding (enabled for plex pass holders) to work, right? thanks for any help. dh22r
  5. i like to have your review for my analysis for best CPU for 4K transcoding. My targets: as much as possible codecs via hardware transcoding, less costs (<80€) , best for future 4K usage During my analysis i checked latest Synology models (here: DS918+) using hardware transcoding (see overview table here: link) Also i added currently used by XPENOLOGY (here: DS916, DS3615, DS3617) And latest my choise; Pentium G4600 Overview DS918+ Intel Celeron J3455 (Appollo lake) DS916 Intel Pentium N3710 (Braswell) DS3615 Intel Core i3-4130 (Haswell) DS3617 Intel Xeon D-1527 (Broadwell) My CPU Intel Pentium G4600 (Kaby Lake) after full compare,91830,77480,91195,97453 i could sort out - Pentium N3710 ($161) and Xeon ($259) and i3-4130($117) as too expensive Update:,97453 Then i had a look to future of 4K transcoding here and here and here and made comparism (did not found available CPU with AV1 Codec ) especially the table with codecs shows me that for me Pentium G4600 is best - 70€ (link, sorry in german) - many codec in hardware and h265 10 bit support - also T-Version with 35watts is available please share your analysis and give me hints if i forgot impotant things for future
