[9900k] Throttlestop resolving issue only by starting it

[Eozen]

Hi,

I had a throttle issue on my 9900k when running a OCCT stress test. It was happening right at the beginning, without any thermal or power throttling.
I downloaded Throttlestop to check the reason(s) but as soon as I start it, the cpu gets back to it's configured speed. I didn't touch a single option. Even if I close the program (not in systray), the issue stays resolved, as long as I don't restart Windows. I thougth of the power plan settings but they are on high performance.

Does anyone know what could Throttlestop do at start that resolves this issue ?

Edit - Options at startup :

Do you use Windows Defender? It has a feature (bug) that loads the CPU excessively which reduces performance. It also changes some of the system timers so monitoring programs like HWiNFO and OCCT will not be able to monitor the CPU correctly. Maybe you have that problem.

I wrote a separate program called Counter Control that lets you test for this problem.

Counter Control 1.2 Download

Counter Control is a small program that will monitor the fixed performance counters on Intel processors. Microsoft's Windows Defender anti-virus so

Try rebooting and run Counter Control without running ThrottleStop. Let Counter Control run in the background. It will log any unusual activity of the system timers. Attach a log file and a screenshot of Counter Control if you see anything unusual.

Another possible problem is that when you disable both SpeedStep and Speed Shift in the BIOS, the CPU might get stuck at a random frequency with no way for Windows to control the CPU after that happens. The solution for that would be to enable SpeedStep. I prefer Speed Shift Technology but having one or the other enabled is not a bad idea. As long as you are using the Windows High performance power plan, you can still run at full speed all of the time with either of these enabled.
