In general, I've been attempting to push my 8600k with Prime95 as a stress test, but the frequency changes unpredictably based on Core Temp and HWinfo data. I've used this approach to assess stability according to the guide, but so far only reached the 30-minute tests. Initially, I tried auto voltage and measured how much power consumption increased as I raised the clock speeds to 4.9ghz, then switched to manual overclocking to reduce voltage usage at the same speed. However, the frequency never maintained the target for more than five minutes before fluctuating, with voltage also changing accordingly, even though both were kept constant. I've also experimented with lower speeds like 4.3ghz at near-stock voltages, but the results remain consistent. I included some screenshots of my settings. It's worth noting that this might be normal, though I'm not sure. Playing BO4 at 5ghz with 1.35v for about four hours without issues was also successful. Any advice would be greatly appreciated!

Ensure you have adequate cooling to prevent thermal throttling. You may want to adjust the following settings in your MSI BIOS:
1. Change Dynamic mode to Fixed Mode
2. Set AVX offset to 0
3. Navigate to DigitALL Power and choose Mode 4 (constant horizontal line)
4. Turn off C-state (access the Motherboard Settings tab instead of the OC tab in the BIOS, locate this option)
5. Most crucially, verify your Power Option after booting into the window.
Control Panel -> Hardware and Sound -> Power Options -> Choose High Performance and NOT power saving.
Alternatively, click on change plan settings, scroll down to Processor power management, and confirm both minimum and maximum processor states are at 100%.

Hi gabbytsai,
What are your specifications?
Mobo:
CPU:
RAM:
Graphics:
PSU:
Could you show the frequency graph so we can observe the fluctuations? You can use afterburner to monitor it.
Rodolphe.

Hey there gabbytsai
As rodolphe.viard mentioned... we would need all your specs.
And YES IF your CPU is getting too hot, it would be normal for the Clockspeeds to fluctuate...
Please do your stress tests again, while setting up a monitoring program, to check the temperature...
Then kindly share those...

Ensure you have adequate cooling to prevent thermal throttling, then consider these adjustments in your MSI BIOS:
1. Change Dynamic mode to Fixed Mode

4. Turn off C-state (access the Motherboard Settings tab instead of the OC tab in the BIOS, locate this option)

Following these steps should stabilize your clock speed.
