PowerSaver C0%

What CPU model do you have? This was a somewhat useful feature for Core 2 Duo processors from about 15 years ago. If your CPU supports the C10 C state, you do not need to be using the old and obsolete PowerSaver feature.

The Package Demotion and Undemotion stuff slightly changes how much load it will take for a CPU core to transition between one C state and another. I think having all of the Undemotion options checked helps improve the C state percentages which in theory might help battery run time when you are running on battery power. With most modern CPUs, these adjustments, whether they are checked or not checked, seems to make very little difference.

Some users claim mouse lag or lag in games that might be related to these settings. You will have to experiment to see if you notice anything good or bad.

Hello and thanks for replying, I use an i7-9750H

9750H

The 9750H should have Speed Shift Technology enabled. The PowerSaver function in ThrottleStop does not apply to modern CPUs.

I have a desktop CPU I5-4690K and it doesn't have Speed Shift.
Does this mean PowerSaver C0% applies to this CPU ?
It shows default 35. Should I set it to 0 or leave it at 35 ?
Also, in throttlestop.ini has HaswellOverclock=15. What is this for?
