Question Power Throttling Intel I7-9700k

[12harvestmoon]

I have a alienware aurora r8 with this inside:
intel i7-9700k
hyperx 32g 2900 ddr4 ram
alienware liquid cooler
rtx 2080 oc gpu
850w gold rated dell psu
The cpu keeps power throttling no matter what setting i have used. temps stay fairly normal and i have tried changing the psu with an exact match but it continues. it doesn't just do it under stress testing it does it no matter what after a while of being on. every time i have stressed tested through dell diagnostics and intel extreme utility it power throttles after about 1.3 minutes regardless of what settings i have tried. the bios doesn't offer many options for power management, only to manage speedstep(i have tried disabling it) and some basic OC functions. If i use the intel utility it maintains a more stable clock speed of 4.6 but still power throttles. Any ideas?

Exit Intel XTU and try running ThrottleStop instead.

ThrottleStop is a small application designed to monitor for and correct the three main types of CPU throttling that are being used on many lapto

Post pictures of the main window, the FIVR and TPL windows so I can see your default settings. Check the Log File box on the main screen and try to play a game for at least 15 minutes while logging data. The more data the better. When finished testing, exit ThrottleStop and you can copy and paste the log file data to www.pastebin.com

it power throttles after about 1.3 minutes

At default settings, that is what Intel CPUs are designed to do. Usually the Alienware line is not too bad when they are setup correctly. For many other Dell computers, the power limits are aggressively enforced and there is little you can do about it. Post some screenshots so I can show you what your options are.

this is what i got this time when i played wow for about 10 minutes, no power throttling yet. did not try to stress test yet. what other settings do you need? i can't figure out how to take a screenshot of bios or if that is possible.

I need to see a ThrottleStop log file. The HWMonitor data does not help.

ThrottleStop shows that the PL1 turbo power limit is set to the default value of 95 Watts. That is not enough power to run a 9700K at full speed. That is why it is power limit throttling.

To fix this problem, in the ThrottleStop TPL window, clear the Disable Controls box and increase the Long Power PL1 value from 95 to 210. That should be OK as long as your liquid cooler is decent.

If this creates too much heat, set PL1 to somewhere between 95 and 210. I set both of my turbo power limits to 300 so they do not get in the way of maximum performance.

My experience with the modern Dell/Alienware is that the case has really poor airflow. They also have big tendency to put a small AIO (think one fan) alongside that poor air flow.

What happens when you open the case fully and check temps under the load?
