AsRock H110 Pro BTC+ with 12 Asus TUF3 RX 5700 XT anybody help me?

The CPU cannot handle all this quantity of GPU... put less GPU... some time that help… with 10 or 11 can work but not 12...

Why? It has 16 lines of PCI-E !

CPU PCI-E lines are irrelevant. All slots besides the main x16 go through the chipset.

the pci voltage is greater for some reason on 5700's.  I have seen them work fine on some boards past 8-9 and others no dice because the board doesn't not have enough power.  If your board has connectors to plug in more power to it do that, if it don't it's more than likely the board.  I can almost guarantee you if you plugged in other cards it would work all of them no issues.

Disable CSM in this way also takes the 13 gpu but as soon as there is a failure in my case it goes to CSM ENABLE and does not start again, it only happens with the 5700 with the 570 or 580 there is no problem

Hello. I just replace my old Biostar TB250-BTC Pro with Asrock H110 Pro BTC+ and I have a problem.
System won`t boot ... after display Asrock logo, I see only one " - " in upper left corner

OS tested : Ethos and HiveOS
Boot : from USB ( i also try to boot from SSD )
VGA : Onbord ( and with 1 or 12 gpus, same problem )
The MB is connected with 2 molex + 1 sata from the same PSU

I made test with same USB in other rig and works fine, also all GPU`s/risers works without problems ... so problem is from MB. One hour tested diffrent BIOS settings without success ...

Thanks and I`m waiting some advices

Remove gpus, go into bios, disable CSM.
On my board with AMD gpus, CSM always gets reenabled if the rig hangs/freezes
