Hi there,

I did a quick Windows live search on "cas latency" and got three very 
good sources of information right at the top of the list. The first was 
wikipedia's article which is very informative and and resides here: 
http://en.wikipedia.org/wiki/CAS_latency

Here is a technical article which examines various memory timings and 
explains them quite well: 
http://www.dewassoc.com/performance/memory/cas_latency.htm

Here's a short and sweet explanation of cas latency and recommentdations 
on what to buy depending on your computing environment:

Hope this helps! Ray Parrish
