Choosing the Right RAM

[Jasonlim]

hi guys, i am new here, and i am really into building my frist rig.

I am a totally know nothing about hardwares, and i am trying to learn more about it.

i have been through certain websites and video guides but still having some of the question not answer.

so here's the thing, how to choose the right ram ?

what does CAS means and what does it affect?

does speed and CAS matters?

CAS is a type of latency and speed is the number of cycles completed. You'll be fine with the typical 1866 speed kits you can find. Higher speeds enable a higher bandwidth, which is great for content creators, but for the average person, it makes no difference.(Same goes with CAS latency)

Higher MHz allows ram to send data faster through the slot and CAS means how many clocks takes for the ram to respond to a command. This means that Games and heavy workload (aplications moving larger chounks of data) will benefit from higher frequency and light aplications (internet browsing, word) will benefit from lower CAS.

Normal is 1600MHz and CAS 9 (DDR3)

thx alot that helped ^.^

the ram i choose was, g.skill trident x, is that good enough or is too much?

[Miguel Sensacion]

If your an average /casual user, the RAM with lower Cas will usually cost more, Value Ram can serve you well if you don't require high performance

i do game, so is the one i choose have good value and performance needed?

[Compgeek]

2400MHz can be overkill. Higher MHz help but not thet much. That is 1.65V ram and i'd keep it on 1.5V.

Something like 1866MHz CL9 ripjaws would be a better choice.

Games don't benefit much from higher speeds. The difference between 1600 and 3000 effective megahertz is maybe 0.5FPS in most games. You can check out Linus' video on that - he did some testing.

I know. I just wanted to point out that heavy loads benefit more than light. The change is not a lot at all but it's bigger than in light loads. IGPs (Integrated graphics processors) benefit the most out of this. I think 1866MHz CL9 is the sweet spot. Highest reasonable clock without compromising on CAS and with barely any price premium.
