Here’s a rephrased version of your message with varied wording:

I recently assembled a budget-friendly system. I selected an i3 13100, paired it with an ASRock B760M PRO RS/D4 motherboard, and installed TeamGroup T-FORCE DELTA RGB 32GB (2x16GB) DDR4 3600MHz RAM, along with a 750W power supply. Although you might think the PSU is excessive, I already owned a used 6800 XT, so I’m considering reusing it for future upgrades to a higher-end build. XMP was enabled, and the BIOS was updated to version 3.11. The 13100’s advertised boost frequency is 4.5GHz, with a maximum turbo power of 89W. When I tested Prime95, the 4-core clocks never exceeded 4.3GHz. Temperatures stayed within acceptable limits during load (70-80°C), and hwinfo didn’t show any cores being throttled. The CPU’s power draw remained close to its base level—around 60W even with a max turbo of 110W, though the PL1 was increased to 70W without noticeable impact. I tried pushing PL1 up to 70W, but it didn’t help. My guess is that the voltage settings are being restricted by some configuration. I’m curious about other factors. I’ve copied all the CPU details from hwinfo below. I realize now that even minor performance drops bother me, so I might return the 13100 for a higher model like 13400 or 13500... I’m still learning more. Thanks! I also noticed that even a small efficiency loss is noticeable, so I’d prefer a better CPU if possible. Your information on the CPU was shared below. PS I’ve learned that any performance drop is concerning, and I might return the 13100 for a higher-end model. Please let me know. I’ve noted all the CPU specs from hwinfo here.

The actual performance comes from a single-core boost of 4.5GHz. The multi-core improvement you see in P95 is typically only 100-200 MHz less than the single-core speed. Running a single-core test like Cinebench will reflect this single-core rate.

The log indicates a 45 multiplier setting for one or two active cores, dropping to a maximum of 43 with three or four cores engaged. Ensure the core C settings are activated in the BIOS to allow this performance boost under light load.

I noticed it in hwinfo and the BIOS, but I misunderstood it as the individual core multiplier.
