Yes. The 667 will run at 533. You should only pair memory with memory of the same speed, cas, timings and voltage.

Thanks for your prompt reply. As I have already purchased the 667 DDR2 RAM and using it along with 533 one. I would need to buy another 667 or 533 so that both the RAM's are having the same speed.

Would it be wise to invest in buying a new one or can I run the current configuration with only the 667 RAM working as a 533 one. (which I can live with). I am only concerned about any damage this setup might cause. Please advice.

don't know about damage but its better to have both rams with same specs. sell your 533 one and get the same 667 one.
