Noobie question about RAM

319 Views 2 Replies 3 Participants Last post by  br3nd064
I'm building a new system and I'm looking at RAM and trying to figure out what to get. Anyways on with my question...

What are the difference between these to sets of ram

Speed: DDR3 1333 (PC3 10666)
Cas Latency: 7
Timing: 7-7-7-20

and say
Speed: DDR3 2000 (PC3 16000)
Cas Latency: 9
Timing: 9-9-9-24

And what does speed, cas, and timing mean?

Sorry for the noobie question.

Speed is how fast it can process stuff and latency is how long per cycle it has to wait to process things thing thats about right here check this thread out will explain better:

In general the faster RAM is the higher the latency will be. The first number or the CAS latency is the biggest factor of its performance as far as timings go. I always say go for higher speed and if you cant use it all with your overclock lower the speed and try to tighten timings.

There are two main things to consider when buying ram: bandwidth and timings. 1333mhz @ 7-7-7 timings aren't that great because you'll be limited when you try to overclock your cpu. Most people balance it at 1600mhz @ 8-8-8 or 9-9-9 timings because of the higher bandwidth.
