What is true latancy (ns) compared to CL?

basically whats in the title, i know very little about memory and i want to learn more about its specification and how to interpret those.

True latency is a physical time. Say, 3 seconds, except in a much smaller scale. CL, on the other hand, is a number of clock cycles; if each cycle takes a second and I have CL 3, it means I have a true latency of 3s.

 

Basically, you need to convert CL into true latency if you want to compare latency between two kits with different frequency.

non-sequential (gaming) latency: 2000 x (CL divided by Speed in Mhz) = latency in ns

so would true latency be a better number to go by when comparing ram sticks? i generally heard that some applications prefer CL over mhz but i don't know how that translates into true latency.

Nonsequential is gaming latency, since people can do anything in a game and access different parts of memory

 

Sequential is non-gaming latency, for Premiere for example, as it uses the memory sequentially

 

Use the formula above for info on non-seq latency, whereas the seq latency is a whole different beast, look it up

wait so ram isn't randomized? or is that a whole different matter altogether? i thought the cpu randomized ram to prevent hacking specific memory regions or something so they can't easily find security keys and stuff like that. or am i completely confusing this and has sequential and non sequential more to do with how the program calls onto memory?
