cl14, cl15, cl16, cl17, cl18, cl19 Difference?

[Avve1000]

Hello! 

Im out to buy the Trident z 3200mhz quad 4x8gb I noticed different pricing for different cl-xx, for example cl14 goes for 4969 kr ($553,81) and cl16 for 4085 kr ($455,29). But what is the difference? which one is the better pick? noticeable?

CAS Latency, smaller number is faster.

That number represents a latency, so lower is "better." DDR4-3200 at CL 14 is faster than DDR4-3200 at CL 16, but it may not be that simple if you're comparing kits at different frequencies.

Smaller is faster but not always better, its workload dependent.

 

What's better for gaming might not be better for editing for example.

Samsung B-Die, which is used in the right sets of G.Skill TridentZ, can handle quite a bit of voltage and scale nicely when pushed.  As an example of this, I can get two sticks of 3200 MHz to run over 4000 MHz dialing in a little extra voltage.  Or I can run it somewhere in between with much more aggressive timing such as c12 or whatever I need.

 

The following sets are Samsung B-Die ICs.  That's what you should be looking for if you're looking for quality binned memory that overclock well.  

 

G.Skill 3200 14-14-14
G.Skill 3600 16-16-16
G.Skill 3600 17-18-18
G.Skill 3733 17-17-17
G.Skill 3733 17-19-19
G.Skill 3866 18-22-22
G.Skill 4000 19-21-21
G.Skill 4133 19-25-25

 

B-Die can also be found in some of the G.Skill Ripjaws sets as well.

What about this memory kit? Do you think it would it be able to go over the 3200?

Short answer: I have no idea.

 

There's a way to look up the revision number on the side of Corsair sticks in order to tell what type of ICs they used for any particular set.  I don't use Corsair so I can't really help you there without researching, which either of us could do.

Thanks. I bought this memory mainly for the color (white model) to fit with my theme Squeezing the extra performance is just some bonus i'll try to do. I'll play with it once i assemble the pc and OC the cpu
