whats faster cas2 or cas3?
isnt cas directly related to latency?

Im building my first system , that is i have computers but all purchased as bare bones or store bought. please read the post " check this out whats the deal?" and see how much tech. info you know regarding same size modules of sd133 ram from the same company at totally different price points.
thank you for reading

Cas2 is better. Yes, CAS is related to latency, more specifically clock cycles.

You're welcome. Actually, that site was just in my signature line.

Here's some information from Crucial:
"CL2 parts process data a little quicker than CL3 parts in that you have to wait one less clock cycle for the initial data. However, after the first piece of data is processed, the rest of the data is processed at equal speeds. Latency only affects the initial burst of data. Once data starts flowing, there is no effect. Bear in mind, a clock cycle for a PC100 module is 10 nanoseconds so you probably won't notice a significant performance difference. Most systems will accept either latency part. However, there are some systems that require either CL2 or CL3 parts."

Hope this helps.

There is also a good explaination of CAS in an article at Sharky Extreme:
