RAM, is it possible to install memory with a higher frequency than the motherboard allows?

Question

RAM

My computer supports ddr2 667, if I install 800 MHz, then nothing bad will happen? You can, but in fact in the BIOS somehow manually lower the frequency. By the way, if so, please explain how to do it. Thanks in advance :))))))
