Hello,
Keeping your BIOS up to date is the best thing I can recommend. However, looking at the tool, it looks like it is kernel module dependent. While doing a bit of looking, I did see a CentOS thread where a BIOS setting was relevant, though. It was pertaining to whether or not the hardware would let the OS make changes to processor performance. You might consider checking to see if the system performance profile is set to allow OS control, or if it is hardware controlled. You'd want to look at the CPU Power Management for Maximum Performance, or potentially OS controlled.
Let me know if this helps.

Yes Dylan, thank you very much.
The problem was (most probably) that I was trying to modify settings via iDRAC.
The net result was
PR31: Job completed with errors.
Maybe that the listboxes do permit nonsensed settings.
Going in virtual console and booting in BIOS via F2 solved the problem!
Thank you for pointing me straight to the solution
