Power Slider

[Lion800]

Hello,

My BIOS does not support speedshift and it seems to default at 128 when I watch it in FIVR window no matter where I move the power slider in windows.

So if I enable Speedshift EPP in TS, will it matter where the power slider is? I’ve seen a YouTube video suggesting to keep it in the middle when using “balanced” and never move it to the right (“best performance”),but I’m guessing this suggestion was for people who have their BIOS enabling speedshift which is not my case (?)

Thank you in advance.

To answer your question, do some testing. The monitoring table in the FIVR window shows what Speed Shift EPP value the CPU is using. This data is being constantly updated.

When ThrottleStop shows SST in green and when Speed Shift - EPP is not checked on the main screen, move the Windows power slider in the system tray back and forth. Watch the FIVR monitoring table for any changes in the Speed Shift EPP value. If Windows is not in control of Speed Shift EPP, I would check the Speed Shift - EPP option in ThrottleStop and I would set EPP to 0 for maximum speed regardless of load. If I wanted the CPU to slow down when lightly loaded, I would set Speed Shift - EPP to 80. I avoid using 128 because this EPP value can interfere with maximum performance.

My desktop computer automatically sets EPP to 0 when I am using the Windows High Performance power plan. When I switch to the Windows Balanced power plan, EPP changes to 84 and when I switch to Power Saver, EPP is set to 153. These are the default values that my computer uses but this can vary depending on the manufacturer. I do not think most desktop computers have a power slider in the system tray.

Yes that's what i did and the number does not change. Thank you. So moving the power slider will have no effect once SST EPP is checked. I'm leaving it to the middle, good?

The power slider can control multiple things including screen brightness. You can set the slider however you like.

When the operating system is not Speed Shift aware because the BIOS does not enable Speed Shift, you can use ThrottleStop to control EPP separately from the Windows power slider. There is no right or wrong setting for the power slider.

Thank you very much.

Another question: when i lower my Turbo limits to 34 and i watch the load percentage in CoreTemp app etc, is the percentage number deducted from the default 41 (pre throttlstop) or is it based on 34?

CoreTemp

If you are using ThrottleStop, why do you need to use Core Temp? ThrottleStop does a great job of accurately reporting what the CPU is doing. The C0% and multiplier data is second to none. I do not use Core Temp so I am not sure whether the data it reports is good or bad or how accurate the data is.

I know the Task Manager - Processes tab is not accurate at all when changing the CPU multiplier. I would not use this data or the Task Manager graphs for anything important. Its CPU utilization data is not the same as CPU usage. Most users assume it is.

Because i did not know you can show many icons in the notification area. You comment now made me look further and realize it does. It was right there in the options
