Hey I have a quick question: Background : My PC (intel i5 12600k with a MSI PROZ690 motherboard) serves as a TwinCAT automation PC. TwinCAT does some fancy stuff with isolating core from Windows so soft real-time requirements can be met easier. I was wondering if I can improve my real-time performance by setting my CPU clock speed at a constant and high value. The idea being that I would not have to wait for the CPU to increase its clock speed. Question : Is it possible to disable all the technologies that adjust the CPU clock based on current requirements? However, I would still like to keep any over temperature protections. If this is possible, I would greatly appreciate if someone could give me a rough guide on what to change (for example via the Intel Extreme Tuning Utility) Greetings Daniel

Check the bios settings, turn off speedstep, then it will use base clock and boost clock. Note: This can also be referred to as EIST (Enhance Intel Speedstep Technology).

Consider choosing a high-performance power profile in Windows. This ensures the CPU maintains boost clocks during optimal settings consistently.

It should match disabling EIST, probably?

That's possible, but I'm not sure.

Disable speedstep and EIST, consider disabling CSTATES. Use a static core frequency around 5GHz (50x multiplier) with a voltage core frequency between 1.25-1.3V. This will keep the CPU locked at 5GHz continuously, preventing core sleep and avoiding clock speed changes from EIST.

Hi, thanks for your message. I turned off the c-states and speed stepping, which made the CPU run steadily at 4.9 GHz. In TwinCAT this improved performance to nearly four times faster. Previously, task times were about 46 µs, now they're around 12 µs. Appreciate the assistance!
