OP, you are a non English-speaking, 3rd world, giant prolapsed anus.  And you've been tagged accordingly.   Stop bringing up these poorly written, poorly conceived scam accusations against people.  You obviously don't know what you're talking about.  If someone doesn't get tagged, suck it the fuck up.  Life isn't fair and police don't chase down every speeder on the highway.   We're all human beings here, except for yourself, who is what I described above.

Do you have other multi-gpu rigs running on h270/z270 boards? Or is it your first one? There's quite a few settings in the BIOS that need to be set for multiple GPUs to work, but seeing how you said you've never had this issue before I assume you know about the standard BIOS stuff, done that before and it's all set correctly? Things like above 4g decoding etc?
