    Sure you have enough power on your psu?

    Thanks for quick reply.
    I'm using 2 PSU , 1st antec 450w for two cards and on mobo.
    2nd coolmaster 500w for 2 rx470 cards

    I can't find 750w or 1000w smps in my area so I'm using two power supplies.

    I think it provides decent powers to cards

    I had the same problem with my RX480 and it was the bios mod. Try to remove it and launch your rig with clean GPUs and see if they run stable.

    when claymore hang it freeze because driver is not reliable for ,at least , 1gpu
    use -r1 and get a reboot.bat file into claymore folder
    or test -wd 0 to ignore gpu lost, but it won't mining if hangs since you'll reboot

    something thats been happening to me after about that amount of time in win 10 with 16.10.3 drivers is the stupid AMD adaptive sleep service
    idk if it installs by itself from the 16.9.2 but u should check ur services tab for it
    that in itself kills the driver while mining is happening creating a freeze cuz of the offsets i have set
