Ram speeds/frequency vs latency

[Attitude12]

I got a couple of questions. I got a Ryzen 5 2600x, want to pair it up with some better ram.

Firstly, is there a big difference between a CL15 and a CL14 kit? Talking about G.Skill Ripjaws V 3200Mhz CL15 (F4-3200C15D-16GVR) and G.Skill Ripjaws V 3200Mhz CL14 (F4-3200C14D-16GVK).

The CL14 one is 25$ more expensive. Is it worth it? I mean, i know they're both B-die and imho it shouldn't matter that much.

I've read that speeds/frequency is for gaming and latency is for editing/rendering/etc. Is that true? I'm interested in gaming only. I only play some games, like 2-4 hours a day and watching movies in the rest of my spare time. So i don't use my pc as a workstation whatsoever.

 

And secondly, on my current B450-F Gaming mobo bios i can select ram speeds up to 4000, even tho' on the asus website it states it can run only up to 3200 (O.C).

If i get a 3400 ram kit, will that work at rated 3400 speeds??

No. Latency is measured in clock cycles and the difference between the two is 30 picoseconds. I think you'd be waiting a long time before the faster latency one manages to do something appreciable.

So, in a real scenario, they'd perform the same. You can't perceive any difference.

Yeah, pretty much.
