Am I the only one who prefers a better performance index? Like, my 3000Mhz CL15 RAM (PI 200) probably does way better at gaming than this 4700Mhz CL39 (PI 120) stuff. Are gamers really this gullible? Does this stuff just make them feel THAT much l33t?
There are two indices that people care about, latency and throughput, and stating freq. and CAS is exactly that (although you have to recalculate latency from cycles to (n)seconds.

It's CL19 running at 4.7GHz making the latency 4,05ns. Your 3GHz chips have 5ns latency. The higher clock means better throughput, so no. This is faster. Also nowadays CPUs (and their mem controllers) are good at guessing what will be next, so the latency is not that big of a deal.
It's actually 3000 / 15 = 200 PI vs 4700 / 19 = 247.37 PI. So the 4700 RAM will be faster than your 3000. I currently have mine run at 4133 / 17 = 243.11 PI.

Frequency has far, far more impact on performance for games than latency.Just mess with your RAM clock speed and timings and run some benchmarks and you will see for yourself.

>Are gamers really this gullible?No, it's you that doesn't understand what this RAM does with Z370 chipsets.

What is the fastest memory that use the normal 1.2 voltage?Surfacround - Saturday, February 10, 2018 - link
tends to be around ddr4 2800...
