Ok well your CPU officially supports DDR4 2400/2133MHz and anything above that are considered an OC.
That's a very decent processor and at that price they should work.
This usually involves Bios intervention to manually enter SPD information and XMP profiles to get them to work. If you are confident in Bios then go for the Higher OC RAM however there is no guarantee they will work. Make sure you can exchange them if they don't as it will depend on the CPUs IMC strength if they scale or not.
Also you can OC your CPU which can help with Higher frequency DIMMs.
