Support for DDR4 3200(O.C.)/2933(O.C.)/2667*/2400/2133 MHz memory modules
* Support for higher than DDR4 2667 MHz may vary by CPU.
The 1700x does support higher speed memory, but you may have to OC the CPU a little to get above 2633Mhz with your memory (currently). A later BIOS rev
may address this.
Looks like your memory can handle it though.
