[SOLVED] Question about RAM frequency in relation to extreme performance.

[Za1zeR]

I'm currently building a high-end PC. Will wait to the Intel 13900KS release, and try to grab a 4090 card. To make sure there is no bottlenecks, I also brought the best RAM I could find (I thought) DDR5 with a frequency on 6600hz. But I have read a lot of talk about that overclocked high frequency RAM's doesn't necessarily affect performances that greatly. My question is how much will the most overclocked RAM like 6600 hz affect performances compared to lesser performance RAM like 5600hz in a high-end build. is there any difference, and if - what, and will it be notable?

Fastest frequency RAM isn't always the best. And it often isn't either.

Here's a vid that Linus made regarding DDR4, but same holds true to DDR5 as well:

DDR5 is mostly untested. In DDR4 the sweet spot is between 3200mhz to 3600mhz beyond which Diminishing Value of Return kicks in. Also, Intel is not as sensitive to RAM as AMD. The principle should be something similar.

So, there should be some performance difference but it might be negligible.
