This is a used X570 Taichi that I had bought to use in a previous build, but due to some issues with RAM I opted to use a different board.

Here's what has been tested and is known to be working:

-LAN: both the Ethernet and Wifi have been tested to be fully functional.

-PCIe slots, including the M.2 slots

-Rear I/O, including the USB-C port

-Onboard RGB lighting and all RGB/ARGB headers

Here is the known issue:

Dual channel configuration DOES NOT work with this board! During testing to isolate the issue, single channel mode, specifically in A1/A2 slots, was the only RAM configuration that allowed a successful POST. Due to this issue, it is only possible to use a maximum of 2 RAM modules.

Because it only works in single channel mode, this is listed for As-Is/For Parts, despite all other core aspects of the board being fully functional.
