In the meantime, you can disable the amd-pstate-epp driver using this procedure: Go to a command line and enter this command: 'echo "blacklist amd-pstate-epp" > /boot/config/modprobe.d/amd-pstate-epp.conf'. Reboot Unraid. You should see the ACPI CPU Freq driver that will allow turbo control.

Just wondering if this is something I should "undo" once support for AMD PSate is better supported. Thanks.

Yes, you will want to remove that entry to re-enable the the amd-pstate-epp driver. I will also have to make changes to Tips and Tweaks to handle changing the turbo mode.

February 24, 20251 yr With the driver "AMD Pstate" you can only set the Governor to "Power Save" and "Performance". "On demand" and "conservative" does not work.

February 25, 20251 yr @dlandon I double checked everything. But it does not work its always the amd-pstate-epp driver. Please check.

February 26, 20251 yr Author Do the following: Click on the "Boot Device" tab. Click on the "Flash" text. Click on "Syslinux Configuration". Add the text "amd_pstate=disable" to the "Unraid OS" box. Reboot Unraid.
February 26, 20251 yr Author The plugin has been updated to add the 'AMD Pstate' and 'AMD Pstate EPP' cpu governor drivers. I believe the 'AMD Pstate' driver will allow boost control, but the 'AMD Pstate EPP' driver will not. The EPP driver is an energy efficient driver and it looks like it controls the boost to conserve power. The CPU modes for each driver are: AMD Pstate - performance, powersave, and schedutil. performance → Runs at the highest frequency possible. powersave → Focuses on energy efficiency by using lower frequencies. schedutil → Uses Linux's CPU scheduler to adjust frequencies dynamically. AMD Pstate EPP - powersave, balanced_power, balanced_performance, and performance. powersave → Prioritizes power efficiency. balanced_power → Balances performance and power usage, with a slight bias toward efficiency. balanced_performance → Balances power and performance, but with a slight performance bias. performance → Prioritizes maximum CPU performance. I don't have a system with an AMD processor, so I have limited testing ability. Let me know of any issues that you see.

February 27, 20251 yr I think this is broken for Intel CPUs. I am on Unraid 7.0.1 and just updated the plug in today. I an running an i9 10900. Before todays update I could select "Performance" for Power Saving CPU Scaling Governor today, my only option is "Power save". Am I missing something? Also, my only options for Normal CPU Scaling Governor are still "performance" and "Power Save". I did reboot after the plug in update for good measure, but it is the same.

What driver shows for the CPU Governor?

These are the governors available for the 'Intel Pstate' driver: root@MediaServer:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors performance powersave Try that command on your server to confirm.

If you saw a change since updating Unraid, then the driver for your processor changed with the latest Linux kernel.

OK so just to confirm, even though in the tips section it is written "If you set the 'Power Save' CPU Governor, you may see your processors stuck at 800 MHz. It is recommended you use the 'Performance' Governor for best performance and power savings." - I simply no longer have that option? EDIT: Upon further inspection, it seems that no matter what I set the Normal CPU Scaling Governor to (performance or power save) the only change that has any effect on clock speeds is setting turboboost on or off. as seen with 'watch grep \"cpu MHz\" /proc/cpuinfo'.

They recommend Performance (you have that choice), for best overall performance and power savings. The 'Power Saving' mode is good for after hours when performance is not important. You can do this using Tips and Tweaks scheduling. I also recommend turning off Turbo after hours with Tips and Tweaks scheduling.

At "Normal CPU Scaling Governor" there is missing "Balanced Power". At "Power Saving CPU Scaling Governor" there is missing "Balanced Performance". And the descriptions maybe need to be updated.

March 6, 20251 yr Good afternoon, Tried to update to current release and it failed. Uninstalled and attempting to reinstall and am getting this:
March 6, 20251 yr DC your dns network settings. when CA plugin file in download its 90% a dns issue. Otherwise, is a misconfigures network setup for unraid and home networking. set dns to google 8.8.8.8 abnd try again.
