i9 10900 k in alienware area 51 r2 doesnt clock down

hye, so as the title says my i9 stays at 4.9 ghz.

i already undervolt it by 100 mhz.

i searched the web for it why and how to let it fluctuate again.

i do this becaus in idle its 70c +- so yeah... could be cooler if it woulndt stay ay 4.9 ghz.

any help apriciated.

What power profile are you using in Windows? 

Intel Core i7-8700K@4.7GHz, -0.095mV  ASUS ROG STRIX RTX 3080 Ti OC LC@2085MHz, 931mV + 20Gbps MEM OC  G.SKILL TridentZ RG4x8GB@3600MHz, 16-16-16-36, 1.35V

Check your BIOS settings

 

Undervolting won't reduce the clock speed,but it may cause stability issues.

Under volt lowers the voltage. Under clock lowers the MHz. Did you under clock your CPU?

 

I have a very similar 10850K. It runs so cool at idle that I have no need to slow it down. I let it run at 5000 MHz all of the time. What type of cooling does your Dell computer use?

If you want your CPU to slow down when idle, use the Windows Balanced power plan. Open up the Task Manager and go to the Details tab. If your CPU is running at 70°C when idle, it is usually because there is something running in the background. Intel CPUs are not designed to slow down if they have a task to perform.

 

How much CPU usage does the Details tab report? Do not look at the Processes tab or the Performance graphs.

 

If CPU usage is low then your heatsink is either inadequate or it is not properly installed.

Given that it is an alienware machine, the air cooling options are not great. I will also second the question about your power plan. I notice when i have Perfomance settings on, i will idle at 30-35C, but any CPU task that is medium to intensive task will take me over 60 really quickly for my 5950X as it is constantly at 5.0GHZ. Turning it to balanced  lowered the clock speed and made the cooling performance a bit more normalized

i let the machine test itself it said is was fine and so far no problems.

it has like 3% use so not much. i also not yet stress tested it.
