The lower the number the faster the ram.:D Here (http://www.lostcircuits.com/advice/bios2/6.shtml) is a really good article for your question.

CAS stands for column access strobe. Mostly you get CAS3 unless you ask for it special. CAS is (I believe) the number of clock cycles it takes to access a memory address. Running at only 2 cycles instead of 3 means running at CAS2 is potentially 33% faster than at CAS3.

You set the CAS to 2 or 3 on your motherboard, based on the ram you want to use. Better study up on the concepts involved a little before you start changing things.
