Like previous generations, the Intel Core i7-8700K is unlocked and also has flexible attributes in terms of the BCLK and ratio/multiplier. This makes the job of overclocking much easier.

While we were able to shift the 8700K up to our current milestone of 5GHz, we required a substantial 1.41v to achieve this and under the current BIOS (7B61v10) we had difficulty getting the CPU to settle at 5GHz under load. Setting fixed or dynamic modes resulted the frequency bouncing between 3GHz and 5GHz. We have spoken to MSI about this, and were advised to modify certain settings which did not alleviate the problem.
