    Ram CAS latency values help please!

    I am looking to upgrade my memory in the near future and have noticed that different types of memory have different latencies and CAS values.

    I want to know if it is better to get ram with higher or lower values and what the values mean etc. Eg. Is 4 4 4 12 faster or slower than 5 5 5 15???

    Also, I have a P4 630 3ghz 2mb cache, 800fsb. Is this processor compatible with 667mhz DDr2 5300 RAM???

    Many Thanks!!!
