your ram sticks claim 3200mhz but your system reports 2133mhz
The display in Task Manager showing 2133MHz might be incorrect or outdated. The RAM and motherboard typically list 32-33MHz, not 2133MHz. Your Intel i9-9900K should run at around 4.68GHz, so the discrepancy suggests a possible display error or misconfiguration. Check your system settings or BIOS for accurate values.
Open your BIOS settings and turn on XMP. This sets the single-core performance boost. It won’t support 5GHz across all cores by default, so you’ll get 5GHz only if: a. your tasks need just one core (very rare) or b. you’ve already overclocked the system.
Yes, you can likely get it to 5.3GHz or higher with your NZXT 280mm CPU cooler. Just make sure the cooler is compatible and properly installed.
You might need to boost the voltage for a steady overclock, and your VRMs could struggle with extra heat without proper cooling. It seems a 5 GHz all-core upgrade is more sensible than a 5.3 GHz on one core.
There seems to be a theoretical upper limit for silicon in insulators around 5 GHz, especially at typical operating temperatures. I’m not sure what the exact value is or how it’s reached, but it might be around 5.3 GHz or higher. Some users have reported achieving 5.1 GHz with regular cooling, while others need more advanced techniques like exotic cooling methods.
