PCIE 1 TO 4 EXTENDER ISSUES

Hey folks,

I have one rig with Asrock BTC 6 pcie. I have two more gpu's to add to my rig. But when I plug the extender and add the two cards in there. Kills the whole system it's like if I fried the board or something, so I have to unplug all the risers(gpu's) from the mobo remove the little battery from the mobo to reset it and turn back on. WTF is this? My mobo does not accept this device? I have two PSU on my RIG, the second one is a 750w EVGA with 2 GPU only so adding the 3rd one can no be the problem. All my cards are GTX 1070, but the one I'm trying to add right now is a GTX 1060 6GB.

Here is the link of the device I'm using: https://www.amazon.com/Extender-Bitcoin-Litecoin-Ubit-Adapter-Ethereum/dp/B073W9KCFC/ref=sr_1_4?ie=UTF8&qid=1516797136&sr=8-4&keywords=PCIE+EXTENDER

Any help?

Thanks

    they don't work, my experience but maybe I am wrong.. You only have so many channels on your motherboard, when you plug this into "1" channel, it doesn't magically create new channels on your motherboard for the other 3 GPU's. They will work with 1 GPU connected to it only. Your motherboard gets confused when it sees multiple GPU's on a single channel..

    They work great. I build many 10 gpu miners on MSI z170a pro carbon mobo. But some chipsets and mobos have limitations about gpus number. Just find one with z170 or z270 chipset and you will be fine.

    Your problem is your motherboard chipset. Your motherboard has a max quantity of lanes.
    I can guarantee this is the problem.

    you have a chipset with a max of 6 pci-e lanes. (H110)

    you need like a Z270 chipset or newer to resolve your problems.

    The Asrock H110 BTC 13 card rig is configured differently from the manufacturer and they somehow get 13 from the chipset... but I also tried a 1-4 splitter and it did the exact same thing. 13 max.

    If you wanted more than 6 cards, you shouldn't have bought a board specifically designed to mine with 6.
    Next time, buy something like this:
    MSI Enthusiastic Gaming Intel Z270
    it would support your 4-1 splitter.

    Or just buy an asus B250 mining board with 19 slots... or the Asrock 13 card board.

    I'm trying to figure out how the Asrock H110 PRO BTC+ can hold 1 PCI-e 16x and 12 PCI-e 1X with this chipset. Any clues?

    It can't. It says max PCI-E lanes is 6. That means no more than 6 devices can use PCIE, so 6 graphics cards and done.


    *Max # of PCI Express Lanes 6

    yea I didn't understand that either. I have the 13 slot BTC+ Pro.

    best I can tell the 12 1x ports are the 6 lanes split.
    I assume in their bios they are doing some sort of trickery. nothing we could do after the fact to resolve OP's problem.


    The last port, the 16x is a PCI-E 3.0
    the max lanes is applicable to PCI-E 2.0 and not 3.0 so that's why it has 1 more than 6x2. (6X2+1)

    That being said, I tried a 4-1 splitter in the 16x port... nogo.
    bios wouldn't post... had to remove battery and hard reboot bios.

    These Asrock boards are FIRM 6 card boards and 13 card boards. No addons will work.

    Yep. Thanks for the help! I just got another mobo to make another rig.
