Since there are so many threads that pop up about RAM speed and CAS latency, this should help with giving a general idea of the relation of different speeds and latencies.
The throughput relation will usually correspond pretty closely to this chart from what
I have seen in my testing.
The latency numbers are in nanoseconds rounded to 3 digits of accuracy.
If you need to extrapolate more figures for speeds other than these, just take the CAS number and divide it by RAM speed divided by 1,000.
CAS / (RAM SPEED / 1,000)
