I currently have 3200 MHZ CL16
Would I see 10-20% fps increase if I upgrade to 4000MHZ CL18?
I know my ram is definitely bottlenecking because on an extremely cpu and ram intensive game I get 90 fps on 3200 mhz but when I push it to 3600 MHZ I get 120 fps
I’m just wondering with the shitter timings of a CL18 would I see a significant difference between 4000mhz cl18 and 3600mhz c16 the way I do when I over clock my 3200 to 3600
If that makes sense.
3200MHz CL16 is exactly the line where you should be fine. I assume you have 2x8GB, right? Which game did you notice an improvment when pushing to 3600MHz? You may also gain/lose a few percent if you put them in the correct/wrong slots - look in your mainboard manual if you are unsure.
No 64GB

Escape from Tarkov
Ah ok, so definitely enough and all slots filled :)
Any benchmark I have seen for the i9-13900k showed good improvements up to 3200MHz (CL16) but only little beyond that. The fastest DDR5 RAM in games is usually <10% faster than mediocre DDR4 RAM.
Regarding Tarkov I saw in detail tests with other CPUs where RAM speed did not really matter - well beyond 3200, there is a Reddit post from someone increasing it from 2133 which helped him a lot (in line with what I saw and wrote before).
