How can i make mmcm block over max.freq?

I'm using vivado v.2018.1 / Clocking wizard 6.0.

I want to make mmcm block, input clock 10MHz, one of output clock 640MHz.

but i got the this warning.

WARNING : clk_out1 output frequencies are out of range for the corresponding buffers. Timing violations may be present.

I ignored this and proceeded. As expected, the timing violation is present.

Any solution of that?
