We overclocked the Core Ultra 5 245K up to 5633 MHz.

That’s possible because of Arrow Lake’s granular ratio tool.

Which enables CPU ratio configuration in steps of 16 MHz.

Not all cores can run that high a frequency, however.

So, we control the frequency using Turbo Ratio Limit configuration.

Then we also overclock the Ring, NGU, D2D, and memory.

Ultimately, the performance increases by +56% when we overclocked the Core Ultra 5 245K up to 5633 MHz.
