Mhz vs CAS

[Anthony10]

Would someone please explain this correctly to me? I have never understood the real difference... whenever I'm comparing RAM I just assume one less CAS = ~250Mhz lol, this must stop now.

CAS is latency and MHz is the frequency.

A High MHz and a high CAS latency cancel each other out.

Take CAS, divide by MHz. That's the time it takes ram to do something. Lower number is better. @TheNinjaNextDor explains what each is.

CAS is latency and MHz is the frequency.

Most of the time a very high MHz and a high CAS latency cancel each other out.

Performance wise though like how do they compare in numbers? Is there a way to know what is faster than what (without testing obviously)

Thanks.

Just look at the MHz and CAS.

1600MHz CL9 RAM is much slower than 2400MHz CL9 RAM.

There is less of a difference here: 1600MHz CL9 RAM is less slow than 2400MHz CL10 RAM than in the example above etc.
