Ebuyer have the 3000MHz kit (that you've listed from ccl) for about another £2, as an aside.
Given it's only a fiver's difference between the 3000MHz and the 3200MHz, and the lack of a 3000MHz divider on Ryzen (see: https://www.techpowerup.com/231518/a...ng-am4-updates), I think I'd go for the 3200MHz kit myself.
