Constructed a PC using a 5700x3d b550 tomahawk and 3600cl14 RAM. Only posted regarding the RAM slots A1 and A2. Tested each slot individually, but no B channel boots occurred. Updated the BIOS without issues, and confirmed no bent pins were present. After assembling, disassembled the unit and returned the motherboard to obtain a replacement. Noted a discussion about the 5700x3d having a faulty memory controller. I also own a 5700x non-3d model that functioned in an earlier system with that RAM.
It seems like this could refer to a problematic memory controller channel.
