Hello! I have the problem that Mother does not want to boot with 4 gpus. I activated the 4g, and updated the bios. But nothing, if I connect 3 they work, I tried them all separately and they work as well.

My specifications;
H270 Plus
G4560
4GB Ram DDR4
Psu evga Supernova 1000w
4x rx 570

I saw 2 topics on reddit but I tried everything they said . Im using smos, the rig dont have hdd or sdd with Windows, may that be?  Thanks for the help and sorry my english!!
