Starting out stock, we see the 9900K bouncing around between 4.3GHz and 5.0GHz as windows does its own internal tasks behind the scenes.
We like to try the automatic overclocking utilities first, and ASUS’s new AI Overclock has worked pretty well so far.
Base on our particular system and configuration, we see an all -core speed of 4.9Ghz and light loads running at 5.0GHz.
This gives us about 150 more points in Cinebench.
Next, we push the clocks to 5.0 GHz on all cores and get another sixty points or so. Temps are still decent as well.
Pushing forward to 5.1 GHz on all cores, we again get a jump in scores, up to 2241 points. Temps climbed a bit more here. We tried for 5.2 GHz but had to push the voltage up far enough we were hitting the 90C range and just wasn’t quite 100% stable. In the end, we settled on a very satisfactory 5.1 GHz all-core speed.
