Using CPU-Z to Stress Test.. but wait.

[r_dettling]

So when I start a stress test my Realtek HD Audio Manager opens up. Then I get a notification that an audio jack has been unplugged, after it says plugged in. I able to close the audio manager during the stress test. I do not know why it opens. Any advice?

That's a pretty bizarre anomaly...

If not a glitch that can be fixed with a fresh driver or OS install, it's doubtful RealTek, the makers of CPU-z, or M$ will ever place much of a priority on it, I'd suspect....depending on who is at the end of the finger pointing...

Well here's a fix ... since CPU-Z --> Bench --> Stress CPU is only about 78% workload, just don't use it ... unless you're comfortable with the false sense of security that your Core temperatures in CPU-Z are really good. 😀

Not all loads are created equal. Intel tests their processors at a steady 100% TDP to validate Thermal Specifications. Prime95 version 26.6 Small FFT's is ideal for CPU thermal testing, because it's a steady 100% workload with steady Core temperatures that typically runs processors within +/- a few % of TDP. No other utility so closely replicates Intel's test conditions. This is the utility Real Temp uses for testing Core temperature sensors.

Utilities that don't overload or underload your processor will give you a valid thermal baseline. Here’s a comparison of utilities grouped as thermal and stability tests according to approximate % of TDP, averaged across six processor Generations at stock settings:

Note where CPU-Z is on the lower end of the scale.

All tests will show 100% CPU Utilization in Windows Task Manager, which seldom coincides with %TDP workload. Higher TDP tests produce higher Core temperatures. Although actual Power dissipation (Watts) varies with Core Speed, Core voltage, cooling and workload, Prime95 v26.6 Small FFT’s always provides a steady 100% workload, whether you’re running stock or overlocked.

Do not use any versions later than 26.6.
