High-speed CPU tuning at 9900K frequency.
High-speed CPU tuning at 9900K frequency.
You're seeing stable performance around 5.0GHz across all cores at 1.225V, which is typical for the 9900K. This indicates the chip is handling the workload well. Without special cooling, you can generally reach similar frequencies with standard air cooling.
Exotic cooling mainly addresses temperature control, not voltage. Could you share your average operating temperatures under load and describe your cooling setup? The details about clock speed and voltage seem relevant.
