but when i turn on my pc at the boot menu the clock of the ram is 1333Mhz ,whats the problem

Becasue the MB will set to the lower RAM frequency (1333MHz) for safty, you need set it to 1600Mhz in the bios.

tanx for answering
but i want to know there isn't any problem with increasing the ram clock?
the motherboard ram clock was set in auto mode and i didn't change it

There is no problem and you can change it to 1600MHz, because your MB can set to 220MHz (OC). When you set to 1600MHz, reboot the PC to see the PC works fine or not. The worst-case scenario is the PC can not boot.
