So what? Memory timing increase proportionally with the speed. CAS latency and true latency are 2 completelly different things.
Please read this article to understand in more details:
http://www.crucial.com/usa/en/memory-performance-speed-latency
https://en.wikipedia.org/wiki/CAS_latency#Memory_timing_examples



As you can see, the Speed and Clock Cycle time are the ones that matter, not CAS timings. The bigger the frequency, the lesser Clock Cycle time is.
true latency (ns) = clock cycle time (ns) x number of clock cycles (CL)
The latest DDR4-4000Mhz have a true latency of 8.911ns. ;)
My DDR3-2400CL9 is 7.5ns. I had some old DDR2 PIs that were 6.7ns (1200CL4). I think overall latency is getting worse. At least density and power draw is getting better though.

So how did you get those figures? Thru an app in windows?
