I currently have 16 ICX 6450's in a ring topology running version 7.X when I try to add a ICX 6450 24-P running version 8.0X it kills the network. What could be wrong? Do I have to upgrade all to the same version for it to work?

Have you tried downgrading the new switch to the same version running in production?

I don't know what you mean by a "ring" topology unless you meen a switching "loop" topology. Those are Ethernet type switches, and that is most likely the reason you are down.
If you DO wire them in a ring for some reason, you will need to ensure STP is enabled on those VLANs and PORTS and blocking somewhere in the ring ultimately making it a daisy "chain"
You will want to do a "show errdisable recovery" and a "show errdisable summary" as well as a "show span" to look at what's going on. I suspec tyou have a loop.
