Rambus Has DDR5 Memory Working in Its Labs, Gears for 2019 Market Release

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:

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?

Manual tuning in the BIOS.

THIS COMPANY IS STILL AROUND???

They're like the Mob. You can't do anything without cutting them in on the action.
