Is my AMD Athlon x4 750K compatible with my DDR3 - 1600?

I have the AMD Athlon x4 750K which (according to here Look in the specs section) only supports DDR3 - 1866. I have only Kingston Blu RAM which is DDR3 - 1600. Is there any problem if I use this RAM with the 750K. Also I'm planning on upgrading it later to the A10-6790K. Will that CPU be compatible too?
