Help in Understanding RAM Speeds

post #1 of 6
Thread Starter 
Of the two listed below, which is faster and why?

6-8-6-24 1.5v

7-8-7-20 1.65v

Both are 1600MHz memory.

I'm not concerned at the moment about which has more overclocking potential (I assume the lower voltage), but rather which is faster at stock speed. I want to understand how memory tmings work and how all these timings factory into performance. I'm told CAS is most important, but from my understanding (or at least how I understand it) the tRAS should also play an important role. Can a 4 cycle tRAS difference make up for 1 cycle CAS difference?

Is there a ram performance calculator somewhere?

they are equal.

the top one since it has a lower timing which will make it faster.

Ahhh but didu see the last timing?

Honestly I don't know much about the whole memory debate. I found this thread to be a good read though (if a bit old):

So 6-8-6-50 would be faster than 7-8-7-20?

Nothing else matters but the CAS?
