Question ASUS AMD Athlon X4 950 not working with B450 motherboard?

[donutcoffee]

I purchased some Athlon X4 CPUs with the intention of using them with B450 motherboards. The motherboard in question is the ASUS B450-I Gaming motherboard. According to this compatitbilty chart: https://i.redd.it/ug2ahg9soo031.jpg, this should work. However, when I plug the Athlon into my motherboard, it just gets stuck in the BIOS screen. Is this CPU and motherboard not compatible or something?
