Starting out stock, we see the 9900K bouncing around between 4.33GHz and 5.04GHz as MSI seems to have the base clock bumped up to 100.8MHz even at ‘stock’.
We’ll start out testing MSI’s Game Boost Function.
We see in the OC section that this does indeed give us a max of 5.1GHz with 2 cores active and scaling down to 4.8Ghz with all cores active.
Interestingly, MSI still holds on to that little extra on the base clock even under Game Boost.
This only gets us about 50 more points in Cinebench over stock.
Next, we’ll push all cores to 5.1Ghz. This puts us very close to our self-imposed limit of 90C max temps, so we’ll go no further.
And yes, we still have that little extra from the base clock giving us a final clock speed of 5.141.1MHz.
Doing this gives us a pretty significant jump in our Cinebench score, almost 10% to be exact.
