      GPU risers are not detected – only if GPU’s are plugged into them is anything detected.

        I was intrigued by this questions as I just built this exact system following Rolf’s post. I ordered a couple of M.2 PCIE adaptors to give it a shot. Unfortunately, while you can connect a GPU to the M.2 slot using the adaptor and during EthOS GPU Detection all 7 cards during. Unfortunately, I got a kernel panic just before EthOS Desktop actually loaded.

        I wonder if this is something ASRock and/or EthOS can fix with a firmware/ software update. Or if this is a permanent hardware limitation of the board. But M2 slots support PCIe so it should work. The board even shows one of the M2 slots at PCIe 5 under EthOS (when used in conjunction with 5 other PCIe slots). Normally with 6 RX580 connected to the PCIe slots on the board, they show up in EthOS as 1-4 and 6, 7.

        I will post this on IRC to see if anyone has any ideas/ experience with this.

          Sorry, rushed in editing…. * during EthOS GPU Detection all 7 cards are recognized and show up on the initial boot screen. But the system kernel panics and hangs just before loading the EthOS Desktop.

            Thanks for giving that a try and letting us know how it worked! I guess it’s better to get one of those boards with 13 PCI-E slots for mining with more than 6 GPU’s.

    Hi Rolf
    Is there any tricks to get the asrock k4 b250 to detect GPUs via USB risers? Have fitted 2 GPUs via USB risers and tried every slot with no detection. Tried multiple gen settings in bios also. Unable to plug into gpu with monitor either, only onboard.

    GPUs work directly to the board with no risers but that’s it.

    Running Windows 10.

    Have verified the risers are not faulty on a friends rig (diff m/b)

    Cheers for any help

    Hello, I have got some issues migrating from 4 to 5 GPU’s but this article helps me to solve them. Thank you very much 🙂

    Currently I have the same issue migrating with 5 to 6 GPU’s.
    The settings are exactly as it is shown on the provided pics. TLUD = 3.5GB
    When I try to boot EthOS – 6GPUs are displayed on the second screen but on the third screen I am getting huge dump of backtrace and a Kernel panic error. Can anyone advice me what to do?

    I am having a similar problem to Chris above.

    These settings allowed me to get from 4 to 5 gpus, but no matter what i do it never recognises the 6th gpu. I can plug any card in, doesnt matter which ones, but as soon as i add a 6th it doesnt recognise.

    Power/risers all work, but cant get it to boot a 6th. So guessing it has to be a bios issue?
