Change ram

Use 2 sticks of 8gb ram 2400mhz… You should use processors like pentium or at max i3… I5 and I7 had many issues with h110 pro btc+…
Btw which gpus are you using and what’s your settings ?

[Grea]

Pentium G4600
8GB Mem
Dual 850 AXi Corsairs (formerly triple 1000w)
(7) RX470/570. (Reduced rig from 12 for stability)

Assuming you had applied the MoBo tweaks to operate more than 9+ cards, there is a funny issue with the board. If you reboot the board without a monitor plugged into the main PCI slot GPU, the CMOS will be enable again, therefore disabling the work with more than 9 GPUs and you will get the black screen and no reboot. To solve this (and not having a monitor plugged), I added a dummy HDMI 4K to the GPU in the main slot and I can now hard reset without issues. I suggest you try to work with 9 GPUs and see if the reboot will work fine. If it does, it is likely the CMOS reset (it should remain disabled and a monitor or dummy monitor plugged)

i have always plug in monitor to main card in pci 16, restar and clear still dont help.

[WenZombies]

How about starting with 9 GPUs or less?
