In my experience squeaking of carbon SMP is caused by the faux-metal silver paint on the rails. If you remove the saddle you will probably find the paint cracked to bits, I could remove it with my nail or a small knife. Getting rid of that, around the clamped area has removed the creaking with my SMP's.
