If my motherboard supports up to 4266mhz RAM frequency, should I max it out?

Recently I found out that my 16GB of Corsair Dominator Platinum 3200mHz DDR4 has been running at 2133mhz the entire time I've had it. I was setting it to 3200mHz yesterday, as it should be, and in the dropdown I had the option to select all the way up to 4266mHz. Should I max it out?
