Your MSI Mag Tomahawk B760 DDR5 has an OC for the CPU that isn't supported. You're stuck at 2.0 GHz and it's likely running slower than expected. Check your BIOS settings to see if there are any performance tweaks available.
It seems the processor supports CPU overclocking, while RAM overclocking isn't available. The chip appears to have VRMs for a 13900 and includes heatsinks, which should prevent overheating and throttling. You're using what tool to monitor clock speeds? HWiNFO64 is recommended, CPU-Z works well for checking active clocks, though some utilities may be less precise. Are you seeing the clock stuck at 2.0GHz regardless of workload or idle state?
That’s typical behavior. At idle, performance tends to drop as expected since power-saving features are active. When under heavy stress, it should rise to match the boost frequency. The figure Intel provides reflects single-core maximum turbo; because Cinebench runs all cores, you’ll likely notice a clock that’s about 300Mhz lower than the advertised peak. With variable workloads like gaming, speeds often fluctuate.
Certain motherboards turn off Intel Turbo Boost during BIOS setup. The base speed of a 13900F is 2.0 GHz, which matches your CPU's performance. https://ark.intel.com/content/www/us/en/...0-ghz.html When using Windows and the processor is active, it should operate significantly faster than 2.0 GHz. Raise the turbo power settings in BIOS to preserve peak performance.
