XPS 9530 Turbo Boost not working

I have completed the Windows 10 clean install and ran all driver updates, 1st by utilizing Dell's Driver AutoDetect tool then by Windows Update process.

Everything seemed to be working until i notice the clock speed on my cpu, i have the i7-4702HQ model and my speed is being maxed at 2.18Ghz.  However, i've owned my laptop for over a year and i've been used to seeing this jump up as high as 3.1Ghz while then idling back down to about 2.8Ghz when doing working in Lightroom, Photoshop, Video converting.

However this isnt so, regardless of that task, my cpu is not "turbo boosting".  I've made sure that my Power Options were not set to prevent the CPU from utilizing 100% power, even on the Min setting.  

Is anyone else having the same issue?
