Thanks for advice, I solved this by putting in old gpu and flashing stock bios, fortunately I saved bios before undervolt... sry for bad english

I am very glad you solved it but you should have said that it was done that way, since the easiest and.most common way of undervolting is by software like msi afterburner, wattman, etc.
If you messed up with vBIOS for undervolting then yes, only reflashing would have help.
