36ms CAS latency. Middle of the road now, but not bad. Best you can get is 30ms, which will cost about 16 bucks more for the less cosmetically enhanced ripjaws version.

36 is clock cycle not absolute time, the first word latency is 12ns. Which doesn't really mean much except to look pretty, Hynix vs Samsung does make a slight difference tho. However you can reliable get Hynix M die for under $150, these aren't slick either.

Even 12ns is high. Ram chip has been stuck around 7ns since SDRAM (not DDR). Last gen (DDR4) chip can get down 6.5ns. The current generation is still maturing. Nice on the bandwidth but terrible on the latency. Depending on the architecture of make use of the latency vs bandwidth. Nice to have both lol!

Like I said, first word latency doesn't do much other than looking pretty, cuz all the work or gaming load is not measuring the latency of finding the first data. DDR5 has been outperforming best of DDR4 comfortably with worse latencies, and you get bandwidth advantages. It's definitely still maturing, 8000ish would be where it should be. But even now it is already pretty solid in terms of cost and performance. I mean we are paying higher prices for DDR4 in 2021 and early 2022 than what we do now for DDR5. $130 DDR5 Hynix dies are better than $200 DDR4 B-dies fwiw

You can easily tighten the timings on this to close to 9ns latency and speed to 7800 with even a mediocre MC on your CPU. In real world use like gaming despite the latency, it outperforms DDR4. We are definitely already at the breaking point where it doesn't make sense to invest in DDR4 any longer with the availability of these SK Hynix M and A dies.
I am able to get CL34 at 7400 stable with the higher density 6400 kit (2x32gb) so these lower density 2x16gb kits should be able to push even harder. Intel 13th Gen anyways, Zen4's memory controller isn't as good and will on "average" only go as high as 6400 but 6000 is typical (CL30).

Ah, you are running Intel platform so DRAM latency has negligible impact on your performance. It is nice that you are able to overclock 6000 to 7400mhz with CL34 especially with a 64GB set. Did you have to bump up the voltage? If so, by how much to achieve 7400 with CL34?
In term of DDR5 ram maturing, there is still a lot of margin for improvement with latency: with 7400 speed, enthusiastic users should be able to get down to CL28 or CL26 with the good chips.

Intel says [intel.com] its latest CPU supports upto 5600 Mhz DDR5 RAM
AMD says [amd.com] its latest CPU supports upto 5200 Mhz DDR5 RAM
so will 6000 Mhz DDR5 RAM provide any performance improvement anywhere in the computer architecture?
