All I know is that it's Cas Latency or something. I don't know what that means? Is it important? What if I use the wrong CL? My mobo docs say CL 2.5 for ram but the already installed ram says CL 3.

it has to do with the memory's timings. Lower = faster.

Praetor went into great detail in this thread.

CAS latency. Lower is better. it's the number of clock cycles it takes to complete a request. If you have 400mhz memory running at 2 cycles CAS, then a request is complete in 2/400 million seconds = 5ns. If you have 500mhz memory running at 3 cycles CAS, then it takes 6ns to complete a request, noticeably longer.

Thanks, so using ram with different CL values won't hurt anything right?

no it won't hurt, may just be slower.
