i9 10900k All core 5.1
to overclock the 10900k to 5.1 with all cores, you've already noticed single-core boost is limited, but achieving full multi-core 5.1 performance may require further investigation or hardware changes.
It depends on your motherboard. I followed a tutorial on YouTube titled "overclocking with msi mag z490" and found many detailed guides on how to properly overclock my motherboard. I plan to spend about five minutes learning everything required. If you have the same motherboard, I can share the link to the video I watched.
The process of aligning most 10900k units to run all cores at 5.1GHz for AVX operations is quite complex. I possess a SP63 chip capable of handling 5.2GHz across all cores with an avx offset. Maintaining efficiency relies on water cooling and controlling power consumption. Reducing power so you can push all cores up to about 200 watts while staying stable, but not exceeding 300 watts for heavy tasks like Prime95 small FFTs, prevents overheating. Without this approach, temperatures may surpass 90°C, which is undesirable. Following my method keeps temperatures under 70°C during gaming and below the maximum of 80°C in general use. Avoiding temperatures above 80°C with normal loads (except Prime95 small FFTs) is essential. If executed properly, you can run Cinebench continuously at full frequency throughout the day without overheating.
Key guidelines:
- Steer clear of the top two LLC voltage ranges.
- Keep voltage below 1.4 volts on the core.
- Ensure temperatures remain under 70°C in games and under the overall 80°C limit elsewhere.
- Limit power draw to reasonable levels, such as 270 watts. In BIOS, you can set short power spikes to 4095W for one second and long durations to 270W. This offers better stability at 270W compared to 270W at 1.4V. Note that Prime95 large FFTs with AVX require around 60°C. Die sensing is consistently below 1.3 volts. If your core senses 1.33 volts in Prime95 small FFTs, you should lower the boost.
