    One more point, on one batch produced of the Clone DM900UHD, they put a 100 Mbps Ethernet chip instead of the original 1 Gbps chip... it seems that who bought the one with 100 Mbps can send back motherboard for replacement of the chip to 1 Gbps, as it is on the Original DM900UHD.

    TS

    P.S.: Concerning the Multistream you see the difference on the Chip reference, that hs a D (Si2169D, as well as what is printed on the blue board, MOD2017/06).

    Thanks TS..now that is very important info.!
    Yes...there certainly are all these different types of Tuners, now it seems also Mother Boards so
    i still need to do some reading, before I make up my mind, about Box and Tuner type.
    Cheers

    You can find all tunners for dm900/920 here - http://dreambox.de/board/index.php?thread/22597-dm920-ab-september/&postID=183258#post183258
    Aliexpress (china) has only two modells; Triple 2x DVB-S2X / 1x DVB-C/T2 Si21692C (not know multistream channels, but know S2x - channels like TF1 from 33 E) and Dual DVB-S2 Twin-Sat-Tuner Si21662B (not know multistream and S2x). Sellers from aliexpress has pictures with last twin tunner who know multistream, but he is just a liar. Most seeler from chiana tell yes to all your questions (yessman).
    I use dm 900 with small cooler - 5V; I have cca 48 grd C.
    I run ethtool on dm900 and supported 10/100/1000 mbps speed. But I think I need driver to connect on 1000 mbps speed.

    root@dm900:~# ethtool eth0
    Settings for eth0:

    @AJP007

    I think that most of the questions you had asked to me are anwered but about the..
    Q: Network speed,
    A: As toysoft already had given, mine has the Gbps chip.
    Q: Silicon Tuner Triple or Twin,
    A: I use the Twin tuner.
    Q: Multi Streams,
    A: I've not tested that.
    Q: Supports true Blindscan,
    A: No clue.
    Q: Cpu temp Clone versus Org,
    A: The precise temp I've not measured, but this I could measure it on Monday.
    In any case since the heat sink from the original is much better, I expect that it will be lower.

    @bibic
    Thanks for the link and the very useful information..Great. ,-))
    Very true about the Dealers saying YES to all our Q's.....that's why i am having such a hard time getting things done and buying my Box with them..some Dealers don't even answer at all...very frustrating.!!!
    Been waiting for my answers to which if any Silicon or Standard Tuners are in the Boxes since Thursday morning...!!!
    Also if they will deliver the Boxes with Silicon Tuners and at what additional cost.!!!!!
    Super List with ALL available DM Tuners..;-)))))

    @Johnny B.
    Yes I think i have all the information now to make up my mind, thanks to you three here.
    Really apprec all your info's and recommendations ..Super..Thank You all very much.!
    I think the Original Box and Twin Silicon Tuner is winning this debacle, so i will take my time now to make a final decision.

    Do any of you Guys know if the Original can take both types of images from Original source and the ones for the SIM2.30...I ask this because their are MORE supported Sim2.30 images and back-ups as their are for the Original.
    I think this is probably the ONLY reason the Sim 2.30 is better.!

    Cheers and Merci Guys

    Does anyone know if the clone bootloader is identical to the original bootloader? I want to rewrite the bootloader, but I did not find it separately for clones. The Chinese sellers are very secretive. They want to test us. I have no problems, but I just want to try. What happend if make "update-rescue -v"?
    Thanks.

    No the bootloaders are different, and your box will be stuck if you load the wrong bootloader to the box. You will have to send it back and DMM or the Clone Manufacturer will have to JTAG it or replace the Flash chip.

    If the bootloader is not different, then I do not see why it would not work. The differences are just the sim, right? And for jtag is used Cypress Board.

    Did you read what I wrote ;o) ? Bootloader IS different, and is linked to the Sim software.

    You cannot do a backup of the bootloader that you can reflash as a bootloader.

    You can only do a dump of the Full Flash and reflash it, but there will be the issue of the Bad Sectors as well... so it could also fail.

    Back to dm800se. Today I installed original oozoone image. Before reboot I replaced drivers from /lib/modules/3.14-1.17-dm900, then reboot. All ok. But after this I wanted to try merlin image. But I make reboot receiver before replaced drivers. Not I have just red led. No IP. Nothing.
    What is pins for connected Cypress Board? The story begins.

    I assume you are still talking about the dm900uhd and want to see if you can make a connection with the cypress board.
    This is of course unknown, so also you need the bbs drivers for these type cpu to make a connection.
    But, as for the scl/sda connections it could be the CN301, pin 2 r303 and pin3 r304.
    in any case, the normal vdc measurements of the scl/sda should be 3.3v.
    If those two has a different measurement then they are for something else.
    Nevertheless, as long you not have the cpu drivers, it has no use to try to make a jtag (I2c) connection.

    I start now (after 2 hours ) with usb cable on serial port. I'll try to send drivers one by one with RealTerm. No network. I dont know why network card not started.

    Your output data is mainly in the aliens language which could be due the wrong settings or driver for the usb.
    It could also be the bps speed.

    Yeah, that looks scary but basically when you upload the correct bootloader it should afterwards be posable to flash the box with the usb.
