racadm command help please for power setting

On an R720 I am trying to change the power setting through the drac via ssh.

I can get the setting but my syntax is wroong in tring to set the setting.

Here is my get:

/admin1-> racadm get BIOS.SysProfileSettings.ProcPwrPerf
[Key=BIOS.Setup.1-1#SysProfileSettings]
ProcPwrPerf=SysDbpm

And here is my set:

/admin1-> racadm set BIOS.SysProfileSettings.ProcPwrPerf MaxPerf
ERROR: RAC1025: The specified object is read-only and cannot be modified due to 
       an object dependency.
       Verify the object dependency using "racadm help <device 
       class>.<groupname>.<objectname>", and retry the opearation.

What is wrong with my syntax?
