Is my ram bottlenecking my i9-13900k with z690-P d4 (alien.top)

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.

3200cl16 is on the slow side. Whether it is bottlenecking or not, its easy to figure out. Just look at gpu utilisation (faster ram is only going to improve gpu util, not magically generate performance out of nowhere). Tbh you will mostly see improvements in minimum fps/1% lows. Also depends whether you wanna invest time tuning the ram or not. Easiest boost you can get (even on your current kit) is trying to run higher trefi value. Just make sure you stress test it thoroughly because you dont want your OS getting corrupted. For ddr4 i would look at either a dual rank 3600cl16 kit or a 4000cl16 kit depending on budget. Just make sure ram is running in gear 1 mode because at gear 2 you are likely to perform worse or on par with 3200cl16.

Yeah I agree with the minimum fps and maximum frametimes. 33.3% higher (I assume average) fps because of 12.5% faster RAM sounds implausible.
