Overclocking the Core i9-10900K wasn’t really that much of a challenge if you know what your’e doing. We managed to bump up the speed to 5.3GHz on ALL 10 cores with a voltage increase of 1.3-1.4V.
In order to achieve our overclocked speeds of 5.3GHz, we had to increase the CPU Core voltage to 1.3V. CPU ratio was set to x53, while the CPU cache was set to x37. All other other settings were left untouched on AUTO.
