about to wrap up my new build purchases.

12900ks i9
MSI z790 PRO (A)
Corsair vengeance 5600 mhz DDR5 64gb (2x32)
1000w Corsair rme PSU
corsair500d airflow
MSI Suprim 3090ti

​

Question, the ddr 5 is at 5600 mt/s where as intel states the 12900ks is only capable of support UP to 4800 mt/s

will this ram work and just be handicapped and bottle necked because of cpu or do i need a new set of ram
