Hi, completed my first build and discovered that my ASRock B550M Steel Legend only accommodates one Nvidia GPU. Asked an ASRock rep and he said that the only board that would work with two is the X370 Killer SLI. Good luck finding one. I have been searching for a replacement mini form factor board that’ll work with an AMD Ryzen 3700X and two RTX 2070 supers. Any suggestions would be appreciated.
