    Hello, please try to  troubleshoot it by fasten the cable and restore it to factory settings.

    If the problem still exists, please contact us at support-cs@bitmain.com again.

    Hello,

    I am facing the same problem with my new D7:

    time="2021-12-30 20:45:00" level=notice pid=5590 chain=0 msg="ChipSetting_get_addr_DASH detect 0 chips"
    time="2021-12-30 20:45:00" level=error pid=5590 chain=0 error="asic num error" msg="detected asic num less than design"
    time="2021-12-30 20:45:02" level=notice pid=5590 chain=1 msg="ChipSetting_get_addr_DASH detect 70 chips"
    time="2021-12-30 20:45:04" level=notice pid=5590 chain=2 msg="ChipSetting_get_addr_DASH detect 70 chips"

     

    The miner won't start even after a factory reset (I can access the dashboard but the message is "

    No data yet! Data is currently unavailable

    "

    Is there a solution?

    BR

    I've gone through troubleshooting with Bitmain and now having to ship it back to Hong Kong at my own expense for repair

    Same in here. they asked me to ship it for repair.
    it is unfortunate that we have to pay for fixing defected products

    My D7 didn't make a dime yet . it failed within hours from first use

    Same to 3 of my D7. Been trying to ask to fix for 4 months three times, spent 6k USDT even they are under warranty to repair by their request, yet not getting fixed...

    Sent mine back for repair, was sent a different unit which worked fine for 3 weeks, this new one is now doing the same thing again, and not hashing, saying missing chips.

    These things obviously have a huge design flaw, or have been made using substandard silicon

    Similar experience here. They repaired unit worked for about 3-4 weeks and then the same board that was repaired broke down again with the same chip number error.
    I already sent it back for repair.

    Invested 70k in these and regretting that daily.
    Bitmain are so ignorant and unprofessional especially when it comes to handling their defected products.

    The only thing i am so sure about is that this is the last time i buy something from Bitmain .
    Intel is joining the mining race so better going with reputable company next time

    sent 4th time, now they fixed this by unplug the power cable to the dead board to show it looks like "fixed".
    When I plug it back, now it shows:

    ChipSetting_get_addr_DASH detect 0 chips

    What a joke.
