Aurora R8, cannot overclock CPU in BIOS or software?

Question

I recently wanted to overclock my cpu since im really getting into games that are cpu based and many people say that overclocking gives huge performance boost to the cpu.I have an Alienware Aurora R8 desktop with an i7-9700k and a 2080 on it. For some reason i cant overclock my cpu from the bios neither can i from the alienware software.When i try to oc from the bios i disable the intel speedshift and the other one and then i restart my pc a couple of times but in task manager  after i have restarted the cpu is still running at 3.6ghz when i have overclocked it to be around 4.9.I have tried to use the alienware command center with both the recommended oc profiles and one that i created.I afterwards restart my pc a few times but still in task manager it says 3.6.I have ever tried putting my system underload but nothing happens.With the i7 9700k im getting some really huge spikes,cpu usage going from 3% to 15% back down and then to 20% and back down. If there is a possible way to fix it pls contact me

How to confirm the over clocking speed?
It is important to understand that the processor will never maintain its top speed all the time on all cores as it will increase the speed depending on the work load.

You can take a single core to max speed to test if the processor reaches its maximum speed by doing the following:

Download prime95 by Clicking Here
Extract the contents of the compressed file
Open prime95
Click Just Stress Testing
Open Windows Task Manager
1. Right Click on the Windows Task Bar
2. Click Task Manager
Right click on PRIME95 Application
Click Go to details
Right Click prime95.exe
Click Set affinity
Uncheck
Check CPU 0 Only
Go back to prime95
Select In-place large FFTs
Click Ok
Go back to the Task Manager
Click the Perfomance tab

The CPU should now show its maximum operating frequency

Important: Even after performing the steps above the top processor speed may not be sustained, keep looking at the information and you may see spikes to the top speed

To Stop the Stress Test go to the system tray, right click on the prime95 icon and click Exit

He disabled Speedshift and EIST(SpeedStep) clocks would be locked to whatever the OC was. However on Alienware boards I believe you need one enabled for OCs to work at all
