Yes, reducing RAM clock speeds can help achieve tighter CAS timings.

You're able to do that if your CPU (probably a Ryzen) can't process them quicker.
Thanks for reaching out! It's great you're exploring your limits and understanding what you're capable of.
Because higher speeds are generally preferred, running at 4000MHz+ memory requires adjusting the memory controller and fabric frequencies. This reduces those high frequencies, which lowers performance. If your UCLK and FCLK exceed 1800MHz, you should allow the memory to operate above 3600MHz (twice the other two).
