Motherboard is a Asrock x370 Taichi, bios 4.70(late April release), Ryzen 1700x(OC), gskill OC to 3200 via built in profile, Toshiba RD400 NVME as boot drive, Vega64. The other 2 were a AsMedia controller and a AMD controller that was found. Of the three originally listed as "Standard SATA AHCI Controller", this was the last. I have extensively pointed the driver lookup to the AMD chipset folder I downloaded both from Asrock and AMD.

There is no "43B5" listed on the driver searches, there are 43B4 and 43B6(Fcc hardware search).

After searching google, it shows as an AMD id, but nothing as far as what exactly it is.
