[For intel cpus, is the CPU overclock more effective than RAM overclocks?]

I have a i7 9700k that is currently running 5 Ghz. I have a Patriot Viper Steel 4133 kit (32 GB) that I havent overclocked at all. Its still running at stock speed. When I use the XMP profile, it just messes up the boot and my computer goes into an endless cycle of starting and restarting.

I was wondering, for Intel CPUs, is the CPU clock more important than RAM overcl VidMate ock (in terms of performance)?  Mobdro

If not, how does one decide what timings and speed combos to use?

I have a 5900x cpu with a 6800xt. My motherboard is a ASRock 570 phantom gaming 4. I recently upgraded my ram to patriot viper steel 4000mhz ... No matter what speeds I put in the bios the settings will not stick.. my PC will boot but the settings do not change in the bios. Can anyone out there help thanks.  https://9apps.ooo/
