    NanoPI M4

    in Rockchip

    Posted

    Hi all.
    I got my M4 today.
    The Lubuntu from FriendlyElec had problems.
    I quickly gave up on it and installed Armbian. Haven't had any problems. Great job with that!

    I'm impressed by the board. The heatsink is awesome. Great it's in this formfactor.
    I've raised the board and put a small 5V fan underneath. It's steady at 60°C maxed out.

    Without the fan it throttles after a while. But not too bad.
    It's a good match to my octa-core SBC's in Blender. The T3+ and XU4 are a bit faster.


    But most important for me is Kdenlive. There it's by far the fastest of all my SBC's.  No idea why it handles it so well.
    M4 34m51s
    XU4 46m23s
    T3+ 1h15m
    Vim2 1h44m
    It always are strange results with that. Finally I've found a good render machine to take with me.

    Youtube playback is also good. 1080p in Chromium is without stuttering. 1/4 lost frames. No other SBC does it so well without hwaccel.


    I'll do a lot more research on it and then make a video. If anyone has more info or suggestions please let me know. Anyone playing linux games on it? (I know, probably wrong forum for that)

    @hjc Thank you for the great info. Did you test the voltage drop on the USB? I've seen dips of 0.4V with sudden bursts without a load on the usb. I wonder if it gets worse with a load.
    The psu they gave with it is very stable. 
    Thanks for the great work.
    Cheers

    eMMC vs Usb Flash on a Rock64

    in Rockchip

    Posted

    Rock64 uses the same eMMC module as the Odroid's. These are among the best eMMC's. Very fast. I don't think they easily break.
    They do cost a bit. And the lower capacity ones are a bit slower.
    I've got 3 of them. 32GB, 64GB and 128GB. Haven't had any problem.
    Thumb drives I've had much trouble with. Many die quickly. Run too hot.
    As @tkaiser said. You have to look out very well not to buy crap.
    But they are cheaper in lower capacity.

    Make backups if you choose to use flash-drives.

    Another informative link to a post of tkaiser. The C2 eMMC's are the ones for you.

    Annoying fan noise on XU4

    in Odroid XU4

    I was able to get it to 49 with new thermal paste

    Did that too. The original paste was a milky white substance. With normal paste it works a lot better. The same with the C2.

    Hmm, any other ideas?

    I`ve got the Q heatsink, plus a silent big 5V fan. I don`t have any noice problem like this.
    https://www.aliexpress.com/item/ALSEYE-5v-80mm-fan-3000RPM-2pin-PH2-0-connector-DC-cooling-fan-radiator-high-quality-exhaust/32785165145.html?spm=a2g0s.9042311.0.0.27424c4d8uKUR2
    I also clock my big cores to 1.8Ghz for long demanding tasks and get better results than at 2Ghz since it doesn`t overheat.

    I`ve once used only my XU4 for a week instead of my pc. What a pleasure not to have the buzzing of that thing.
    That fan is not controlable so it`s always on. You could make a script and power with gpio`s to stop it when not needed.

    Another RK3399: Khadas Edge

    in Off-topic

    Posted

    Not really a single board computer is it?
    I don't understand this design.  The core module has usb and hdmi ports. Other peripherals on the carrier board. Why?
    Don't see any pcie ,m.2 or sata.
    And indeed no heat sink holes.
    Who has come up with this design, and why?
    I can't see a benefit here.
    I'm wondering what this will cost.
    Cheers

    the 7-zip link here https://github.com/ThomasKaiser/sbc-bench#7-zip then you get an explanation what's going on at the bottom of that page:


    Just seen that your Rock64 results are with a 2GB. I'll do the same with my 4GB. Just interested if there's a difference with 7zip multicore. It's only 4-cores tho.
    Now doing Blender bench between Xenial default and nightly.  Again just out of curiosity. I red it's now clocked to 1.39Ghz.
    I'll give you the sbc-bench results later if they're interesting. I don't think they will be. It's already 100%...

    Eidit : Blender just crashed on 1.39Ghz after 30minutes. At 1.3Ghz no problem : 1h17m55s
    I'll try again. Maybe it's not stable enough.
    2nd try did it. So could be a fluke the crash.

    Xenial Rock64 4GB results : http://ix.io/1j7d
    Again very different than other distro's.

    I'm also wondering if zram would make a big difference with the 8-core 2gb devices?
    Cheers

    What do you think about the fact that 7-zip multicore never uses close to 100% of the cpu's? Would we need to take that in acount?

    Here the NanoPC-T3+

    NanoPC is around 75% and the XU4 is wel below 70%.
    Would we get "more useful" numbers if we did for example
    for xu4 : 8734/68 * 100 = 12 844
    for T3+: 10226/75 * 100 =  13 634.6666....
    Just a question.

    I use Blender because that uses 100% of all cores.

    When I do that it reboots the sbc.
    Then I can't do that again(no such file), so I did sbc-bench, but no difference. I don't know.

    I'll do the Odroid XU4 with Ubuntu 18.04 from Odroid now.

    LOL, jamesh's excuse for the RPi always showing only faked cpufreq readings is really funny

    Yeah. I don't like his answers. He tries to minimize it, and tries to change the subject from "not giving true clocks" to, "we did it for the good of the users". Well, then inform your users...
    It doesn't seem like they are willing to change anything. It's there choice.
    I contacted ETA-Prime and told him about it. He seemed very intersted. I hope he'll make a video, then there forum will explode with unhappy comments.
    I'll stay polite. I know I'dd have the whole RPi-fanboyclub after me if I wouldn't.
     

    I'm amazed you stayed out of it :lol:

    I'll start doing some more sbc-bench's.

    I'm surprised to see that the NanoPC-T3+ seems to do better than the XU4 in multicore. And almost everything else...
    It does outperform the XU4 in Blender too.


    Here the scores from zador.blood.stained XU4

    Since I had this image installed on eMMC and the board was ready to use I ran a benchmark and it produced +/- similar to already present in the table results.

    Also T3+ vs T4 is interesting. T3+ outperforms in all Multicore tasks.
    @tkaiser
    Could you do the bench with the T4 again with 2Ghz/1.5Ghz?


    Here the results for the Odroid C2 : http://ix.io/1iSh

    All expected results when it's not overclocked.

    Yep. Funnily this kernel reports /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies in descending order so after checking the cpufreq OPPs the lowest frequency is set. Please check out latest release, I hope this and that fixed it. 

    http://ix.io/1iRJ NanoPC-T3+
    The changes did the work, but indeed no space left. Just checked with gparted, it shows that the partition sda1 is 59GB.
    No idea if I'm doing this right.

    I can't do anything about that link on the RPi forum. It always shortens it. But if you click it it sends you to the right page.

    NanoPC-T3+ http://ix.io/1iRu
    Something is clearly wrong. It's stuck on 400Mhz. Before the bench's it tests all frequency's. Does it turn it back to original?
    It's with the Armbian you asked me to do.

    My first try gave this a couple times

    "line 419 : command not found"

    This was the result.

    I've finished my video. Here it is.


    I had to keep it simple. As always I forgot to mention a lot of information. I don't script to save time, but it also shows in the (non)quality of my work.
    Thanks for all the help and info.
    Now I can begin with the other sbc's. You'll hear from me.

    RPi Trading employees decided to cheat a little bit more.

    I'm currently downloading the rpi-stretch from 13/03/2018. Release date of the 3B+.
    I'll do the same on that. We'll be able to compare those.
    I'll keep posting my results.
    I found the bad 2.5A very interesting. Also my 2A PSU did very well. So I can show it isn't the amperage but the voltage that's important. Everyone always says, buy a 2.5A or 3A...
    Thanks for all the info. I'm learning every minute. Cheers.
    ps. Check above post for more results. I'll keep it all there to save room on this thread. RPi 3B now comming.

     

    @tkaiser

    Check the 3B no fan vs 3B+ no fan. The 3B outperforms the 3B+ until it overheats to +80°C.

    Ok. I'm on it. Now doing the Rasp 3B+ with the new script and no cooling. After that I'll do the same with a crappy psu.

    Indeed on some I use old distro's. I'll do it again with newer ones. I also have got Tinker Board, BPi M2-Zero, OPi +2, ... that I'll do too. It'll take me some time.  Cheers
