Overclocking

Now that we have completed all our stock testing lets see if you can get 5.0GHz on all the cores as advertised. Below are the stock settings for my 9900K and Team Group Vulcan memory.

I personally haven’t overclocked this 9900K chip yet, so it will be some trial and error to see what voltages are required at what clock. The first thing I tried was the included EasyTune software which has AutoTune that will automatically overclock your system. Once I ran AutoTune, it did some diagnostics, rebooted my machine, once I got into Windows, I immediately hit a BSOD. It looks like my 9900K didn’t like AutoTune to much so I’ll go ahead and manually set my own clocks and voltages.

I did manage to hit a stable clock of 5.0GHz on all cores with a vCore of 1.355v and overclocked my memory from 3200MHz to 3600MHz. I did try and go for 5.1GHz but could not get it stable with keeping acceptable temperatures below 90c.

Now that we have a stable system let’s run some more benchmarks and see how much more performance, we were able to achieve.

In AIDA64 we see an increase between 6-12% in write/read/copy performance with a slightly higher latency of 47.8ns.

In Cinebench, we score an impressive 2179 which is 104 points above our stock score.

In Time Spy, our score was only slightly higher but we did achieve a 397-point increase in CPU score.

In Super PI we were able to beat our previous score by 5 seconds.
