I'm not sure why, but when I updated from unraid 7.0.4 to 7.1.2, the Balanced mode became greyed out (not selectable), and the low power and high performance options don't change anything.

Can we have these brought back to their former glory? My server would only pull 165W on the previous low power mode, now it won't go below 205W (both times are with all my disks off).

Thank you

Which CPU?

Ryzen 5950X. I did see a post regarding the 9700X Power Mode as well. So I simply need to add the following code to my syslinux.cfg file in order to utilize the older CPU drivers, which will then in turn bring back the expected behavior before I experienced in Unraid 7.0.3?

kernel /bzimage

append initrd=/bzroot amd_pstate=disable

Yep, that should do it, but the new driver is supposedly better.

High Jorge. I added that code like you said, and it didn't do anything for me. I will have the Balanced Mode greyed out. Did I do it incorrectly? I went to Flash drive -> syslinux (folder) -> syslinux.cfg

Once I added that code and rebooted, it was the same. Any ideas?

Thank you.

That wasn't added correctly, change the view to menu "Menu View" and add it to the default boot option, the one in green, after bzroot, like the mitigation option was added here:

Oh! Ok I understand. I did that and I now have all 3 Power Mode options available. But I do see what you mean about the newer driver being better. My Ryzen 5950X is able to boost past its base clock (3.4 Ghz) with the newer driver to 4.7 Ghz, whereas with this option (or prior to Unraid 7.1) it would top out at its base clock again.

The new driver has some options that may not be exposed in the GUI:
