Yes - I built a pair of machines - one mini ITX B350 motherboard with a 2400G CPU/GPU & the second an X370 board with a Ryzen 2600 that used a GPU I already owned.[1] The first came with an updated BIOS & the 2400G worked out of the box. The second came with it's original BIOS. Both were ordered from Amazon. If you order from a smaller outfit they’ll hopefully be able to tell you whether the motherboard box has the sticker on it that says that its BIOS has been updated to cope with Ryzen CPUs. [1] Still hoping for the great crypto-currency crash in the sky to bring down GPU prices. In the meantime the 2400G is adequate for console grade gaming on the TV.
