A little help with RAM speed

Hi, I have a question about my RAM configuration. I checked CPU-Z and saw that my RAM is set to 2140 MHz, not the 3000 MHz it should be. My friend mentioned adjusting the XMP profile in BIOS, so I changed it to profile #1. After that, the PC ran fine at 3000 MHz. But when I played a game like Horizon Zero Dawn, I noticed stuttering and significant FPS drops. After running a benchmark, the issue disappeared, though there were occasional stutters. I disabled the XMP profile in BIOS and re-running the test fixed the problem. So, why would increasing RAM speed matter? Could using a lower speed actually hurt performance in games?

My setup:
- CPU: Intel i7-8700
- GPU: Asus 1080 Ti
- RAM: Ballistix Elite 3000 DDR4 16 GB (Single Slot)
- Current setting: XMP disabled, 2140 MHz
- BIOS: Profile #1 enabled

I found the info on Amazon and checked the screenshots. Thanks!

Your processor is currently secured, with the highest performance it can handle being 2666 MHz.

The RAM speed might not match the CPU, but it shouldn't affect performance. Your storage will simply need more time to load or unload apps such as Blender.

ohhh i didnt knew that, and is there a way to set it to 2666 mhz?

Activate XMP and adjust your connection speed to 2666, which should resolve the issue.

Absolutely, no need to worry about them. You're all set!

If stability problems appear when XMP is active, consider adjusting your RAM speeds and timings manually.

It’s not overly complicated. Enabling XMP with profile 1 displayed recent changes, including CL and voltage data. If you want similar insight, consider enabling it again or adjusting RAM speed as well.

Turn on XMP, implement updates, then reboot. The computer is unlikely to function properly if you modify just the RAM speed, since increasing it further demands greater voltage.

I already did that, but it looks like it becomes unstable during gameplay. CPU-Z shows the DRAM frequency at 1500 MHz (maybe 3000 MHz?), and when XMP is enabled, it sets the RAM to 3000 MHz instead of the expected 2666 MHz.
