Overclocking Tests
Intel has made much of the extra frequency headroom enabled by the latest iteration of its 14nm process - more current, same power.
Cranking up the voltage 1.35V and raising the all-core multiplier until the system could no longer complete at least 10 minutes of the intensive Blender test, we settled on a final speed of 5.1GHz, or 600MHz faster than stock. This, we believe, is a conservative speed for this CPU, and it's exactly what the Core i9-9900K managed.
As you can see, temperatures remained very decent, especially as the system was air cooled. For those interested, under-load wattage jumped from 148W to 199W, or still less than a 'stock' 9900K.
You simply cannot beat having more cores and threads at your disposal, though.
