Here's an FYI for anyone thinking of upgrading from Ryzen first and second gen to the third gen.

Unfortunately, many first and second motherboards on the market are going to be inadequate or incompatible with Ryzen third gen. The first gen boards have a unique issue to them, the motherboard makers put too smaller bios chips on their boards so there is literally not enough memory on the board to hold the entire third gen bios. Many first and second gen boards and some third gen boards (FFS ) also have inadequate VRMs to run the 3800X or higher.

So if you are upgrading or even building a new Ryzen system there are some potential pitfalls.

For anyone wondering it was MSI that said not all of it's third gen boards are designed for the high end 8, 12 and 16 core Rzyen 3000 parts, so maybe don't buy a MSI board.
